Just wanna make sure I’m doing this right I have 2 subwoofers 300 watts each side so total 600 watts and I’m doing 2 ohms so would I do 300 x 2 or 600 x 2
u will if u put it up 100% must head units clean sound stop around 70-75% if u don hear distortion then ur fine if u do back down just a lil bit till its clear and that good for ur speakers and subz. and yea u could put up some bass on the head unit but the same goes for if u hear distortion.the max volume number, multiply it by .75, this will get you 75% of your max volume. For example, if your max volume is 60, then 0.75 x 60 = 45 hope that helps
my amp says it has 1050watts rms at 4 ohms my 12s are wired at 2ohms should i check my rms coming out of the amp to see what im acually getting then use a converter to find what volt my gain should be set at?
well thanks you see what is my prepossess for making the video i may have missed a part that i found out after i made the video that if your Rms watts of your amp is rated by the voltage of the car like12.5v then you leave the car off like the first turn of the key to tune it. if the Rms is rated at 14.4v then you turn your car on in idle to tune it
so you have to disconnect your front and rear speakers to be able to use the test tone and not damage your front and rear speakers? as my front and rears are on the HU's amp
disconnect the speakers and tune the amp for the amount of Rms your looking for its just so you dont go over and put your amp into protect mode then hook everything back this is just a simple way for you not to keep buying amps there are better ways out there.
no problem bro. when i can i reply. and thats cool your getting one. another idea if you like it i have another car now a honda civic hatchback and i hooked it up to my alternator and added a switch in the inside so if i like i can turn it of and for me it well tell me whenever my alternator is blown cuz i will have a constant reading of 12.whatever volts and dropping and also show how much volts is drawn from it.
Here's how I do it EXAMPLE: 300watts rms X 4 ohms = 1200watts square root of 1200 is 34.64 so you set you amp gain to 34.64 volts that should be the power handling of that sub. So what you do is get a RCA to 3.5mm jack adapter download a tone generator app and plug directly to your amp, I use 50hz tone volume all the way up then take a multimeter set to AC volts and adjust gain to that voltage btw make sure your speakers unpluged. BTW disregard peak power and always use RMS ratings it's more accurate.
yep that's the best way i learned a lot more after making that video years ago but did have the time to make a new video... hope people see your comment and do that better then i showed.
@@ElvinBryant Trial and error that's how I learned people expect you to have all the answers instead of clowning on you they should help out you if they know better.
Ok, thats great so i can tune my speakers to say 60rms and add a little bit more bass on top, so it's less chance to over load them. Will that be an option? I don' mind runnig them a little less power as they produce enough sound already.
Did you say you turn the low pass filter all the way up on amp? I tried the same tuning procedure with my low pass filter set around 80hz on amp, the highest reading I could get were 8v. Will that effect the output not having it turned all the way up?
Can I apply this square root formula to any amp?? Even if it's different numbers in the manual? I'll definitely give it a try next week and see the difference. Thanks Elvin!
Hey Elvin! A bit more help please, lol. Right, I tuned my amp as you showed in the video, calculated, everything is fine, but just one question.. Will it blow my speakers if I turn 100% on the stereo? And if I turn more bass on the amp and stereo will they go? I tuned them to 70rms each speaker. THANKS!
Little off there. That formula is correct, however you used the wrong input. The RMS watts you need to consider is that of your speakers, not what your amp is rated at. Your amp always needs to be bigger than your speakers. If you set your gains according to the amp's specs you could very easily blow your speakers. 'A' for effort though.
@ekim andersom if you want to clip your system and ruin your subs then sure, but if you want to have a functional system, get an amp that is of higher RMS rating than your speakers. You can always turn the volume down but if you keep trying to turn it up you will clip. If I have a 500 watt RMS amplifier, and a 1000w RMS sub, I will never ever be able to get the full potential out of the sub. It will probably sound like garbage. However if I put a 2000 watt amplifier on a 1000 watt sub and set the gains properly, I will get the full potential out of the sub and have plenty of Headroom for the amplifier which will give it a longer life-span. Being as though I live with electrical engineers, and am currently going down that path, I think I know what I'm talking about. That's like trying to fill a gallon jug with a shot glass. It's easier the other way around. Bigger amp, smaller sub, is ALWAYS the best way to go.
hi friend, im a bit confused on how to figure out the right voltage for my amp. i have a 400watts in 4ohm all the way 650watts rms in 2ohm soundstream picasso nano monoblock amp. driving a one piece 12" 4ohm dual voice coil kicker cvr woofer. i paralleled my dvc woofer so it become 2ohm. my question is, can you help me figure out the right calculation or the right volts i need to tune my amp? sorry for my english. thank you.
so your trying to run the amp on 2 Ohms which will be 650 RMS right ok then make sure the car is running when you do this i figured that out after i did this vid but on the MM your going to look for 36.06 Ac volts if you want to change your ohms here is an app that could help you its called (Ohm's Law) Start with the RMS (Watts) of the Amp then the (Ohms) then on the top the app will give you your (AC volts) hope i could help.
Elvin Bryant yes,im running on 2ohms. thank you and now i understand everything you explained. your advise will really help me a lot. crystal clear. thanks again friend. :)
ok one last question after i tune it without the eq can i use it afterward and can i set the setting on my stereo the way i like?thks for the replied..
I had an old kenwood head unit just like that with the cd changer,gave it to my friend and he never used it to this day i have no idea what he did with it, that unit put out alot of power and it tunes speakers and all,don't know why i ever got rid of it,oh i know ! wanted a dvd player multi media with less power,lol.
I'm a little confused, the math you did was 200x2. Meaning the 200 is rms watts, and the 2 means how many channels or ohms? I have 1800 watts going to a dual voice coil 2 ohms each so in parralel the line is 1 ohm, does that mean the equasion would be 1800 x 1 channel ohm whatever.... giving me a square root of 42.43. So the volt meter should read 42 volts? I have two of these setups so essentially I'm running 3600w total but I'm guessing I tune each amp separately using your method? Any advice would be great thanks

thanks bro and i didnt use a fuse cuz you cant short it out but if you want to you can. and i ran the wiring to the ignition wire on the radio harness and the ground anywhere on the car or find a ground wire and tap into it.
That's good scrutiny but it's pretty well known you can play about 20% over the rms rating of your speakers and not damage them. Better to over power than underpower. Honestly, I just appreciate the fact that this video was so in depth
@@A4rings110 dude that was eight months ago I don’t even remember what I was talking about. I do remember hearing that 20% over rms is normally safe for nice subs
+Elvin Bryant and before you run your mouth buy some name brand shit..and learn how to hook up your power wire..who the fuck puts a ring terminal on the amp..lmao glad you like it cause that's some cheap shit.and before you talk shit about oh you probably don't have a system..rockford fosgate punch 6.5 components in the front and back doors..rockford 600.4 for those a bd1500 and 2 p3 15s so shut up..

I have a 900 watt peak amp and two 4 ohm sums in the same box brought down to 2 ohm each what should my ohm ready say when I do this? Would do 900 x 2 or 400 x 2?
I had to gain my bass booster a lil along with my gain all the way up to get the 28.2 not sure if I did everything right just don't know if I should be using the 900 watt X2 or the 400 watt x 2
Ok so I should have read the comments and did not have the car running this time I did and had the base booster all the way down and had to turn the gain down just a lil to get it to 28.2 still not sure if I should be using the 900 X2 or 400 x 2
not saying you're trying to be the best, just stating that i've followed this procedure in the past and it completely fried the voice coils on a set of 6x9s because at the time i didn't know any better than to believe the specs on the boxes would be accurate, also one of his earliest videos on setting gains was with an o-scope, unfortunately they're costly and i'm hunting for a shop with staff who do know how to do it, last place i looked at were useless, quality service is hard to come by
Little late lol but you should check volts at battery terminals, and then check volts on the ground and power on amp to see if volts are being loss. If your losing .5 volts or more then you need to either find a better spot for ground or get a smaller gauge power wire(smaller gauge=thicker wire).
Thanks I have learned a lot sense this vid... I truly appreciate your tips and for not being stupid like some others on here not realizing how long i made this video lol
@@slitherman7883 no it just confirms loss of performance, it confirms theirs a weak point in your system, check volts at battery, then check volts at power input on amp (keep negative prong on battery and put positive prong on power wire at the amp) and vice versus for the ground connection at amp (positive prong on battery terminal negative prong on ground connection at the amp)
@@davidstillwell8091 yes but if you have a weak spot and are not getting the right voltage to make enough power wont it clip sooner when setting the gain
@@slitherman7883no clipping if ur gain and other amp settings are set correctly, only effects the power to the amp not the power to the subs. Ur volts to subs when setting gain that you should check using a volts meter will stay consistent whether you have a strong or weak connection. Your amp is just being over worked is all effected. I have 2 Rockford fosgate p2 D2s with a one channel 900 rms Hifonix amp 2 ohm load so each sub gets 450rms… 900rms at 2ohm load is 42.4 volts at whatever max Volume I set stereo at, I never turn stereo up above 28 in my case... also did a test with a 4 gauge and an 8 gauge power wire, volts to speaker Stayed the same 42 whether I had 4 or 8 gauge power wire. But my volt drop was .09 with the 4 gauge .7 with the 8 gauge when checking from battery volts and power to amp volts but volts to subs never changed….. if you want to give me a run down of your set up what subs and amp you have and whether you have a sealed or ported/vented box I can double check what your current volts are..
how do you know your head unit distorts at 24? only accurate way to be sure would be with an oscilloscope to find where it clips, if you went to those lengths why not use the same tool measuring where the amp will begin to distort since the ratings on the box are not always trustworthy. one other side note, i don't know whether that capacitor keeps the voltage at 12 but when you start your engine i can guarantee you'll be getting more power through the amp than what you measure in this video
Ive done this before and the only problem I had is my gains seemed to be set to low with this method. I just watched avideo of this guy who used a tweeter with a 200v 2.2uf non polorised capasitor wired in series with the amp load. When a amp clips it puts out a very high frequency that the tweeter setup will alow you to hear. I have not tried this yet but as soon as I find that capasitor I will.
you want to hook the amp straight to head unit and then run whatever hurts 80 or 50 you prefer and try to get 64.80 with your head unit @ 75% of ur volume an Ac volts On ur VM if you have a Equal or anything when you get that 64.80 then connect EQ and then put it to whatever you feel comfortable.
hi all, just a question... does that multimeter measure Rms voltage ? i guess not so your 20V is peak ...multiply by 0.707 to get RMS voltage and put that figure in the calc to see how much power you have . most car amps are rated on 14.4Volt so start your car.personally i would just listen to the sub or other speakers to check when they are clipping , cheers
OreyoGaming yes that's right sorry back then I was not the best but I'm glad you saw what I was meaning.. make sure the car is running, and all settings are at 0 and when you set it at 63 plug everything back then you can tune it more just don't touch the gain again...
my amp didnt have a subsonic filter but if up do turn that bown as well on o when you are tuning make sure the car is running. i learned that after i did this vid
Hi all. My amp manual says RMS Power@14.4V, into 2Ohm = 800w so this square root doesn't mach the car amp manual. If I calculate with the square root i need 40.00V which is three times greater than stated in the manual. Does this formula apply to every amp or is it something I don't understand? Should I fallow my amp instructions? Please help! :(
Add both subs tru rms. Then make sure the rms from the amp match or a lil bit more the tune the amp to the 2 ohm amount so 800 rms should give u 40 volts. That's wat ur amp gain should be tuned to hope that helps is anything else let me know
Need help. I have a DB drive speed series 900.1 @2ohms and two 12" kicker cvr 400w rms 800w max @2ohms. Now i set the gain at 40v using the ohm law. Everything cool until i raised the bass boost and frecuency. Now it went up to 43v. What now?
If you want to get THE most from your car stereo system you need to use an O-scope to determine the maximum useable volume setting for your HU. To do this your test tone needs to be recorded at 0dB. My Pioneer HU has a volume range from 0 to 40. It's maximum useable setting is 38. At 39 the signal begins to clip. To get the most from my amps I like to set their gain using a sine wave recorded at -10dB. This will give you the best trade-off between signal to noise ratio and maximum undistorted output volume. Using the "set your HU at 3/4 volume setting" method will NEVER get you results as good as knowing exactly where the HU's maximum useable volume setting is.
Hey dude, I noticed you commented on another related video saying this. I'm just wondering why you would use a tone at -10dB vs. a 0dB tone. Is it because bass in most songs rarely exceed -10dB or what? And still, in that case, the kick can still reach 0dB. What's the methodology behind the -10dB?
hey what if i put in my diseired watts rms like 400 cuze my amp puts out 720 watts rms x2 and want to have set the gains low cuze i dont need to blow my subs "yet" jk but wouldnt it work better if i just put my diserd rms instead in science my subs wont 400 watts rms each wouyldnt that work for me please meassage me back i need some help?
yes that will wotk thats what im doing to my system now cuz my new amp is 720 rms and my subs are 400 i just listen to the sub and tune it so i dont hear any distortion so again yes it will work.
by making sure nothing is playing then max your volume divide that number by 0.7 which is 70%.. most head unit distorts at 70% or 80%. and if look at the voltage that way then have ur car running with 14 volts tune it the same way and see if that make a difference let me know
+Elvin Bryant no problem two terms that you can read up on to familiarize yourself with what causes distortion are clipping and clamping. I haven't looked for anything online and my solid state classes are old school from 86-89 so I could be a bit out of date. a good unit back then would have a set of class B push pulls for the finals. On each channel at the output there would be 2 identically match power transistors, the top half of the audio signal is actually amplified by one of the transistors (push) because it uses voltage to control its output. It pushes the voltage on the upper half the signwave higher do to the way it is configured in the circuit called biasing and the other uses current to control it's output pulling the bottom of the signal through. they are very efficient as each one only has to amplify half the signal cutting the number of duty cycles by 50% this may. even a bit above or you may have knowledge in this I don't know your level of experience and I'm not a real good teacher I'm just trying to share a little. Oh clipping happens on the upper portion of the signal and clamping is distortion of the lower half. An audio signal as you probably know, on an O scope looks like a jagged up and down line going across the screen. clipping would look like the top of the signal would be cut off at the same height across all the peaks. Clamping would be the same thing to the bottom peaks of the signal. On a scope you see this very clear. I'm guessing I haven't even see the inside of a unit in decades maybe they have operational amplifiers OP Amps that can handle the audio now days in which case they deal in digital square wave signals but that audio signal being sent to your power amplifier or triaxials I'm pretty sure is analog. PS Sorry for the book.
+Elvin Bryant It is still a good video and great for you to reach out to others. I have a son who keeps after me about helping him make a youtube channel but I have never looked into it nor have I read the first paragraph on how to. He is always coming up with these little projects then he says I wish I could youtube that lol he's a pretty cool and very talkative kid, maybe this weekend I can find some time to read up on it. Anyway it's been a pleasure and I'm just a post away :)
You can use loudness after setting the gain, but only at low volumes like it is meant to be used. If you use it at high volumes you're gonna have distortion or clipping which defeats the purpose of doing all this.
Rather than go through the trouble of using the fader and/or disconnecting the front amp, why not just set your high pass filter above 50Hz to protect the 6x9in speakers up front? I would guess you should probably have the system crossed over above 50Hz anyway.
@@ElvinBryant i have 500.1 rockford amp gain 1/3 or less.. freq at 80 hz punch eq turnd all the way down . only thing i can think of is this factor premium audio head unit that comes in the 07 civic si is crap
i throw the music to only the back speakers which is the 6*9'z and then go back there and unplug them both so now the only thing that should be playing is the subz hope that helps
That's a good idea man. I seen your toggle switch in this video and I wondered if that's what it was for. Nice set up. I'm gonna run a toggle switch to. I like lots of extra gadgets.

I have it line out from the head to a Kenwood eq then splitt 3ways f/r/s to a crossover to two different amps is that the right way or should I just sub from the head to get a quality low with no distortion? Thxs in advance for any advice
Ceelo totheworld OK as you thought just use from the head unit straight to each amp not the crossover. but if you want to do it the best way possible get the SMD equipment it will calibrate both amps on point and make them both equal with your frequency your trying to reach
bass booster is if u tune the bass on your head unit in the negatives then you boost the bass and listen for distortion, the low pass filter you look at the numbers on the amp and try to eye it to the Hz you trying to push. in other words just turn the low pass filter knob to the Hz you require, there are things on the market to help with those fine tuning now.
You set your gain with a test tone and then you're gonna hook everything up and readjust your EQ, including the HZ frequency you used in the tone. Isn't that gonna throw off the rms voltage of 19.9 that you had and clip/distort the signal. Personally I would have set everything from 100 HZ and below(on your EQ) to flat or default instead of unplugging it. I also believe that your fade has to be centered when you're doing this. Anyways, good video, and like you I recently tuned my amp this way with the truck off. I need to go back and redo it with the truck on, lol.
thanks for the info bro yea i had to go back after the vid to do it with the car on lol, but with my new car im now going to buy the really things to tune the amp and EQ correctly
That's great man! I'm looking forward to seeing that on video. Yeah i'm going to retune my amp tomorrow and experiment with reversing the phase. Can't stop messing wih the damn system lol
Actually I have one or two of my system, but I'm not very good at making videos and the damn Iphone won't pick up the bass from my sub. It sounds very smooth and blends in nicely with the music, unlike others here that like to overpower the speakers.The video just doesn't do it justice and I don't have a real camera to take video.
You did it wrong... Its the RMS output of the amp x the speaker ohm load you are using squared. So it would be say 200 x 2 if the ohm of speaker you input is 2 ohm
the thing is, you CANNOT tune it 100% correctly without an oscope. The "chart" you speak of is more of a guideline than what he amp actually does, therefore it is inaccurate before you even start measuring anything. All amplifier boards are different and each one has a certain max ACV it can output before clipping, the chart doesnt account for these variances, meaning it is inaccurate
it's been proven multiple times that if you set gains with the car on but not running then once the car is running the output voltages will increase, only way to avoid that is having a filter that restricts it to a 12v system but most amps are designed to run their best at 14v, but either way its distortion that cooks speakers, i'm wishing i had an o-scope to actually set mine up properly, i didn't overload the speakers but they still cooked because this test doesn't account for clipping
Turn your low pass filter to 80. Having it at 50 is ridiculous. 6th order bandpass enclosures have the smaller side tune higher than 50 hertz... that would be horrible for sound quality. I'm sure on the inside of the amplifier it has a second-order low-pass filter, therefore if it starts to roll off at 50 it's probably going to stop at around 80. And nothing else will come out of the subs. That means that those door speakers need to play 50 hurts very well to keep the bandwidth of the usable frequencies. What I'm saying is you're having to make your door speakers push 50 hertz to make up for the lost bass. Door speakers shouldn't play any lower than 80. That means between 50 and 80 you have missing frequencies. And the ones you do have are very low on the dB spectrum. Turn your low pass filter up to around 80. That's where it should be. That's where almost every one of them is.
If you're doing the math based on the specs on that sheet then you're gonna be way off regardless coz there is Nooo way on God's green earth does that Pyramid piece of shyt put out what it's rated. I guarandamntee if u put an O Scope to it you're clipping!
Congratulations, you played yourself... Can't have self-contradictory statements there bud... It's either over or under, not both. And you don't get clipping from "under" powering it, so doing it by the numbers is fine if your argument is that it's "not" going to push RMS rating.
How the hell its 200x2 or 2000x2 , how is that possible? I mean it makes no sense that the same amp is rated at 200 or 2000w just a small difference. And why didn't you do the 2000x2 to get the full power if it's capable to 2000rms right or is it just 200 rms and 2000 who knows what
Journey girl that sings all kind of wrong and I don't know Jack anyting about stereos explain why your setting things where you are setting them are all subwoofer supposed to be low pass filter that 50 hertz??
the RMS 14.4v into 2ohms= 800w on the manual means that the amp will give u 800w rms when the car is running @ 14.4v. ur car gives out that when u start it but when its off u'll get 12.4v or so the formula will work with the 800w by 1 im amusing........ the 40 is what ur looking for on the M.Meter when u turn ur gains up.
oh ok i c. well this is the way i do it for now and it haven't failed me yet i dont want to spend that much money on O-Scopes and shops. im not trying to go into sound a competition or anything like that lol and i buy certify amps that is trust worthy for there RMS rates.. sorry to hear that this method didnt work for u. check out the link in my description.
Treble.... The word you were looking for is......treble lol.
I know what it is.... remembering other things I had to say had me a bit overwhelmed.... the things people get a joy over smh.
Thanks; I didn't have my car on and had my sub volume on flat. Think I got it very well tuned now.
ok glade you got it now yea i should have don it in the vid sorry
Boss youre ground needs to be same size or bigger than ur power wire you must be getting really bad connection to that amp .
🍕Austin🍕 I figured that out sometime later but thanks.
Thank you!! Been looking everywhere for this video!!
What if your aunt isn’t directly hooked up to your head unit it has a line out converter in the middle does that change this at all?
Just wanna make sure I’m doing this right I have 2 subwoofers 300 watts each side so total 600 watts and I’m doing 2 ohms so would I do 300 x 2 or 600 x 2
OMG, he has an equalizer now? Oh and I love the 24 gauge speaker wire. Probably aluminum wire at that LOL.
u will if u put it up 100% must head units clean sound stop around 70-75% if u don hear distortion then ur fine if u do back down just a lil bit till its clear and that good for ur speakers and subz. and yea u could put up some bass on the head unit but the same goes for if u hear distortion.the max volume number, multiply it by .75, this will get you 75% of your max volume. For example, if your max volume is 60, then 0.75 x 60 = 45 hope that helps
because it is a common Hz that most ppl use it is not to low and not to high, Do u have a suggestion that i should of use?
my amp says it has 1050watts rms at 4 ohms my 12s are wired at 2ohms should i check my rms coming out of the amp to see what im acually getting then use a converter to find what volt my gain should be set at?
I like the in-dash volt meter. Did you have to use a fuse with it? Where did you run the power wire? Thanx
well thanks you see what is my prepossess for making the video i may have missed a part that i found out after i made the video that if your Rms watts of your amp is rated by the voltage of the car like12.5v then you leave the car off like the first turn of the key to tune it. if the Rms is rated at 14.4v then you turn your car on in idle to tune it
How do you get it so the test tone dont play in the car speakers? I played it and it sounded like it was going to blow them up lmfao. 60Hz tone
so you have to disconnect your front and rear speakers to be able to use the test tone and not damage your front and rear speakers? as my front and rears are on the HU's amp
disconnect the speakers and tune the amp for the amount of Rms your looking for its just so you dont go over and put your amp into protect mode then hook everything back this is just a simple way for you not to keep buying amps there are better ways out there.
no problem bro. when i can i reply. and thats cool your getting one. another idea if you like it i have another car now a honda civic hatchback and i hooked it up to my alternator and added a switch in the inside so if i like i can turn it of and for me it well tell me whenever my alternator is blown cuz i will have a constant reading of 12.whatever volts and dropping and also show how much volts is drawn from it.
Here's how I do it EXAMPLE: 300watts rms X 4 ohms = 1200watts square root of 1200 is 34.64 so you set you amp gain to 34.64 volts that should be the power handling of that sub. So what you do is get a RCA to 3.5mm jack adapter download a tone generator app and plug directly to your amp, I use 50hz tone volume all the way up then take a multimeter set to AC volts and adjust gain to that voltage btw make sure your speakers unpluged. BTW disregard peak power and always use RMS ratings it's more accurate.

Ok, thats great so i can tune my speakers to say 60rms and add a little bit more bass on top, so it's less chance to over load them. Will that be an option? I don' mind runnig them a little less power as they produce enough sound already.
Did you say you turn the low pass filter all the way up on amp?
I tried the same tuning procedure with my low pass filter set around 80hz on amp, the highest reading I could get were 8v. Will that effect the output not having it turned all the way up?
make sure the car is running and yea turn it all the way up and after you get the DMM reading then you put it down to the Hrz you want?
Hi I have a addictive audio 1260 elite amp and 2 mtx 10s thunder 8500s 500watts or rms 600 peak each how would I see my settings?
How much ohms are you wiring the two speakers? If its 4ohms and you amp RMS is 500 look for 44.72 on the DMM if its wired at 2ohms the look for 31.62
Its at 1ohm
Oscar Rivera then look for 22.36
Oscar Rivera do you know how to find the peak volume number on your stereo before it distorts?
No lol I can put it up all the way and it still sounds the same to me I have a bose system 7 speakers I think 6 tweeters
Can I apply this square root formula to any amp?? Even if it's different numbers in the manual? I'll definitely give it a try next week and see the difference. Thanks Elvin!
i honestly thought i was running 10 watt to my amp, i did the math wrong haha. Thanks for showing the math.
Hey Elvin! A bit more help please, lol. Right, I tuned my amp as you showed in the video, calculated, everything is fine, but just one question.. Will it blow my speakers if I turn 100% on the stereo? And if I turn more bass on the amp and stereo will they go? I tuned them to 70rms each speaker. THANKS!
Little off there. That formula is correct, however you used the wrong input. The RMS watts you need to consider is that of your speakers, not what your amp is rated at. Your amp always needs to be bigger than your speakers. If you set your gains according to the amp's specs you could very easily blow your speakers. 'A' for effort though.
Thank you for clearing that up apparently other humans beings don't know how to give good criticism.
No problem. Gotta start somewhere.
@ekim andersom if you want to clip your system and ruin your subs then sure, but if you want to have a functional system, get an amp that is of higher RMS rating than your speakers. You can always turn the volume down but if you keep trying to turn it up you will clip. If I have a 500 watt RMS amplifier, and a 1000w RMS sub, I will never ever be able to get the full potential out of the sub. It will probably sound like garbage. However if I put a 2000 watt amplifier on a 1000 watt sub and set the gains properly, I will get the full potential out of the sub and have plenty of Headroom for the amplifier which will give it a longer life-span. Being as though I live with electrical engineers, and am currently going down that path, I think I know what I'm talking about. That's like trying to fill a gallon jug with a shot glass. It's easier the other way around. Bigger amp, smaller sub, is ALWAYS the best way to go.
ekim andersom you usually want an amp capable of pushing your sub to its full potential.
hi friend, im a bit confused on how to figure out the right voltage for my amp. i have a 400watts in 4ohm all the way 650watts rms in 2ohm soundstream picasso nano monoblock amp. driving a one piece 12" 4ohm dual voice coil kicker cvr woofer. i paralleled my dvc woofer so it become 2ohm. my question is, can you help me figure out the right calculation or the right volts i need to tune my amp? sorry for my english. thank you.
so your trying to run the amp on 2 Ohms which will be 650 RMS right ok then make sure the car is running when you do this i figured that out after i did this vid but on the MM your going to look for 36.06 Ac volts if you want to change your ohms here is an app that could help you its called (Ohm's Law) Start with the RMS (Watts) of the Amp then the (Ohms) then on the top the app will give you your (AC volts) hope i could help.
Elvin Bryant yes,im running on 2ohms. thank you and now i understand everything you explained. your advise will really help me a lot. crystal clear. thanks again friend. :)
Jonathan Castro anytime friend
ok one last question after i tune it without the eq can i use it afterward and can i set the setting on my stereo the way i like?thks for the replied..
I had an old kenwood head unit just like that with the cd changer,gave it to my friend and he never used it to this day i have no idea what he did with it, that unit put out alot of power and it tunes speakers and all,don't know why i ever got rid of it,oh i know ! wanted a dvd player multi media with less power,lol.
I'm a little confused, the math you did was 200x2. Meaning the 200 is rms watts, and the 2 means how many channels or ohms? I have 1800 watts going to a dual voice coil 2 ohms each so in parralel the line is 1 ohm, does that mean the equasion would be 1800 x 1 channel ohm whatever.... giving me a square root of 42.43. So the volt meter should read 42 volts? I have two of these setups so essentially I'm running 3600w total but I'm guessing I tune each amp separately using your method? Any advice would be great thanks

thanks bro and i didnt use a fuse cuz you cant short it out but if you want to you can. and i ran the wiring to the ignition wire on the radio harness and the ground anywhere on the car or find a ground wire and tap into it.
after im done with the tuning can i put my subwoofer +15 settings back on or do i need to put it on when im tuning the amp?
you can but you have to listen for distortion if any just back of the bass booster or whatever you are using
now what about when you start your engine and you get a 14.4v flow?
when your engines off your only getting 12v
That's good scrutiny but it's pretty well known you can play about 20% over the rms rating of your speakers and not damage them. Better to over power than underpower. Honestly, I just appreciate the fact that this video was so in depth
@@nathan-fh8hp lol who told you it's better to overpower than underpower?
@@A4rings110 dude that was eight months ago I don’t even remember what I was talking about. I do remember hearing that 20% over rms is normally safe for nice subs

Hey bro what setting did u use on ur multi meter??????????
Ac 200 put make sure your car is running
I have a 900 watt peak amp and two 4 ohm sums in the same box brought down to 2 ohm each what should my ohm ready say when I do this? Would do 900 x 2 or 400 x 2?
If you are using 900 watts x 2 then it's 42.43 if you are looking for 400 watts x 2 then it's 28.28 on you multimeters.
I had to gain my bass booster a lil along with my gain all the way up to get the 28.2 not sure if I did everything right just don't know if I should be using the 900 watt X2 or the 400 watt x 2
Ok so I should have read the comments and did not have the car running this time I did and had the base booster all the way down and had to turn the gain down just a lil to get it to 28.2 still not sure if I should be using the 900 X2 or 400 x 2
hey man i have a 350rms sub can i connect it to a 800rms amp???????? will the sub get bad???
yo elvin the yellow instrument you are using what is it the one you set to repeat
My iPod which is hooked up to the head unit
cool,so your resitance is 2 ohm's thats at 14 vdc rite .the car on
a. jahja 4 ohms and with the car on
not saying you're trying to be the best, just stating that i've followed this procedure in the past and it completely fried the voice coils on a set of 6x9s because at the time i didn't know any better than to believe the specs on the boxes would be accurate, also one of his earliest videos on setting gains was with an o-scope, unfortunately they're costly and i'm hunting for a shop with staff who do know how to do it, last place i looked at were useless, quality service is hard to come by
Maaann ... great vid.. and did u build that box? I like that work on the trim.. again ... great vid!
thanks bro well i found the box on the side of the road i just paint the front trim blue
Is it the total rms power of the amp x resistance? or just the rms of the channel im using?
For the channel that or channels that is used
Little late lol but you should check volts at battery terminals, and then check volts on the ground and power on amp to see if volts are being loss. If your losing .5 volts or more then you need to either find a better spot for ground or get a smaller gauge power wire(smaller gauge=thicker wire).
Thanks I have learned a lot sense this vid... I truly appreciate your tips and for not being stupid like some others on here not realizing how long i made this video lol
does this cause clipping or a sub to get hot if so
@@slitherman7883 no it just confirms loss of performance, it confirms theirs a weak point in your system, check volts at battery, then check volts at power input on amp (keep negative prong on battery and put positive prong on power wire at the amp) and vice versus for the ground connection at amp (positive prong on battery terminal negative prong on ground connection at the amp)
@@davidstillwell8091 yes but if you have a weak spot and are not getting the right voltage to make enough power wont it clip sooner when setting the gain
@@slitherman7883no clipping if ur gain and other amp settings are set correctly, only effects the power to the amp not the power to the subs. Ur volts to subs when setting gain that you should check using a volts meter will stay consistent whether you have a strong or weak connection. Your amp is just being over worked is all effected. I have 2 Rockford fosgate p2 D2s with a one channel 900 rms Hifonix amp 2 ohm load so each sub gets 450rms… 900rms at 2ohm load is 42.4 volts at whatever max Volume I set stereo at, I never turn stereo up above 28 in my case... also did a test with a 4 gauge and an 8 gauge power wire, volts to speaker Stayed the same 42 whether I had 4 or 8 gauge power wire. But my volt drop was .09 with the 4 gauge .7 with the 8 gauge when checking from battery volts and power to amp volts but volts to subs never changed….. if you want to give me a run down of your set up what subs and amp you have and whether you have a sealed or ported/vented box I can double check what your current volts are..
how do you know your head unit distorts at 24? only accurate way to be sure would be with an oscilloscope to find where it clips, if you went to those lengths why not use the same tool measuring where the amp will begin to distort since the ratings on the box are not always trustworthy. one other side note, i don't know whether that capacitor keeps the voltage at 12 but when you start your engine i can guarantee you'll be getting more power through the amp than what you measure in this video
Ive done this before and the only problem I had is my gains seemed to be set to low with this method. I just watched avideo of this guy who used a tweeter with a 200v 2.2uf non polorised capasitor wired in series with the amp load. When a amp clips it puts out a very high frequency that the tweeter setup will alow you to hear. I have not tried this yet but as soon as I find that capasitor I will.

what about subsonic filter on the amp?? whats it need to be set to in order to make this happen??
Hey bro what if i got a preamp hook up to it? Dmm will not read with preamp hookup but when i ran it str8 without the preamp then it read u know y?
you want to hook the amp straight to head unit and then run whatever hurts 80 or 50 you prefer and try to get 64.80 with your head unit @ 75% of ur volume an Ac volts On ur VM if you have a Equal or anything when you get that 64.80 then connect EQ and then put it to whatever you feel comfortable.
hi all,
just a question... does that multimeter measure Rms voltage ? i guess not so your 20V is peak ...multiply by 0.707 to get RMS voltage and put that figure in the calc to see how much power you have . most car amps are rated on 14.4Volt so start your car.personally i would just listen to the sub or other speakers to check when they are clipping , cheers
Why do u have your low pass filter all the way up???
so if its 1000w*4 Ohms=4000, square root is 63.24, i put gain up to where meter says 63 and its good there?
OreyoGaming yes that's right sorry back then I was not the best but I'm glad you saw what I was meaning.. make sure the car is running, and all settings are at 0 and when you set it at 63 plug everything back then you can tune it more just don't touch the gain again...
my amp didnt have a subsonic filter but if up do turn that bown as well on o when you are tuning make sure the car is running. i learned that after i did this vid
what prerecorded frequency to use for mid-range and high end frequency
123Hz To 1000Hz
Hi all. My amp manual says RMS Power@14.4V, into 2Ohm = 800w so this square root doesn't mach the car amp manual. If I calculate with the square root i need 40.00V which is three times greater than stated in the manual. Does this formula apply to every amp or is it something I don't understand? Should I fallow my amp instructions? Please help! :(
Add both subs tru rms. Then make sure the rms from the amp match or a lil bit more the tune the amp to the 2 ohm amount so 800 rms should give u 40 volts. That's wat ur amp gain should be tuned to hope that helps is anything else let me know
Square root of 800 is 28.***Volts, not 40. Where's the 40 keep coming from?
Maybe we are both confused about something but multiple 2 x800 and you get 1600 then the square root of that is 40.
the right hrz that your amp can handle and so that the amp don't overheat and go into protect mode
Where did you get your digital voltage reader on your dash?

Need help.
I have a DB drive speed series 900.1 @2ohms and two 12" kicker cvr 400w rms 800w max @2ohms. Now i set the gain at 40v using the ohm law. Everything cool until i raised the bass boost and frecuency. Now it went up to 43v. What now?
You don't need the bass bosster
So I tune the Gain only?
Yes sir
+Elvin Bryant alright, thank you
Set the Gain to 24.49v using a Voltmeter
If you want to get THE most from your car stereo system you need to use an O-scope to determine the maximum useable volume setting for your HU. To do this your test tone needs to be recorded at 0dB. My Pioneer HU has a volume range from 0 to 40. It's maximum useable setting is 38. At 39 the signal begins to clip. To get the most from my amps I like to set their gain using a sine wave recorded at -10dB. This will give you the best trade-off between signal to noise ratio and maximum undistorted output volume. Using the "set your HU at 3/4 volume setting" method will NEVER get you results as good as knowing exactly where the HU's maximum useable volume setting is.
Hey dude, I noticed you commented on another related video saying this. I'm just wondering why you would use a tone at -10dB vs. a 0dB tone. Is it because bass in most songs rarely exceed -10dB or what? And still, in that case, the kick can still reach 0dB. What's the methodology behind the -10dB?
Who carries around a sine wave? :P
Anyone who wants to set gains correctly lol
hey what if i put in my diseired watts rms like 400 cuze my amp puts out 720 watts rms x2 and want to have set the gains low cuze i dont need to blow my subs "yet" jk but wouldnt it work better if i just put my diserd rms instead in science my subs wont 400 watts rms each wouyldnt that work for me please meassage me back i need some help?
yes that will wotk thats what im doing to my system now cuz my new amp is 720 rms and my subs are 400 i just listen to the sub and tune it so i dont hear any distortion so again yes it will work.
Elvin Bryant thanks man for the help
by making sure nothing is playing then max your volume divide that number by 0.7 which is 70%.. most head unit distorts at 70% or 80%. and if look at the voltage that way then have ur car running with 14 volts tune it the same way and see if that make a difference let me know
is there any way you can check your headunit when it distortes with a multimeter if so can you make a vedio how thanks
+Rudy Reyes Depends if it is distorting because of saturation current or over voltage. An O scope works nice to look at the signal.
+Jim Hamilton thanks Jim
+Elvin Bryant no problem two terms that you can read up on to familiarize yourself with what causes distortion are clipping and clamping. I haven't looked for anything online and my solid state classes are old school from 86-89 so I could be a bit out of date. a good unit back then would have a set of class B push pulls for the finals. On each channel at the output there would be 2 identically match power transistors, the top half of the audio signal is actually amplified by one of the transistors (push) because it uses voltage to control its output. It pushes the voltage on the upper half the signwave higher do to the way it is configured in the circuit called biasing and the other uses current to control it's output pulling the bottom of the signal through. they are very efficient as each one only has to amplify half the signal cutting the number of duty cycles by 50% this may. even a bit above or you may have knowledge in this I don't know your level of experience and I'm not a real good teacher I'm just trying to share a little. Oh clipping happens on the upper portion of the signal and clamping is distortion of the lower half. An audio signal as you probably know, on an O scope looks like a jagged up and down line going across the screen. clipping would look like the top of the signal would be cut off at the same height across all the peaks. Clamping would be the same thing to the bottom peaks of the signal. On a scope you see this very clear. I'm guessing I haven't even see the inside of a unit in decades maybe they have operational amplifiers OP Amps that can handle the audio now days in which case they deal in digital square wave signals but that audio signal being sent to your power amplifier or triaxials I'm pretty sure is analog.
PS Sorry for the book.
+Jim Hamilton oh thanks I know how to do it now this video is 4 years old, in this video was my first try on how to lol by little research
+Elvin Bryant It is still a good video and great for you to reach out to others.

After setting Gain can i put back the LOUDNESS setting On
You're stupid..... He just said his gain up to 20.0. If you put loudness on after that he will get 24 or 23. that's axactly the thing we don't want...
You can use loudness after setting the gain, but only at low volumes like it is meant to be used. If you use it at high volumes you're gonna have distortion or clipping which defeats the purpose of doing all this.
Rather than go through the trouble of using the fader and/or disconnecting the front amp, why not just set your high pass filter above 50Hz to protect the 6x9in speakers up front? I would guess you should probably have the system crossed over above 50Hz anyway.
nice idea, if you want yea you can do the but for me just as a safety i faded it and disconnected with im not using.
Arent you supposed to do calculations based on the speakers RMS?
Vincent Sanchez yes that's what I did
Wat test tone do you use for mids and high
I'm mostly cared about the sub amp going into protect mode mids and highs was not really my concern as much.

Do u use the sub out from the head unit?
yea i did
I have it line out from the head to a Kenwood eq then splitt 3ways f/r/s to a crossover to two different amps is that the right way or should I just sub from the head to get a quality low with no distortion? Thxs in advance for any advice
Ceelo totheworld OK as you thought just use from the head unit straight to each amp not the crossover. but if you want to do it the best way possible get the SMD equipment it will calibrate both amps on point and make them both equal with your frequency your trying to reach
OK great thxs for the advice
I don't know anything about amplifiers but my amp does not say gain
all it has is bass boost, x over freq, x-over, sens HELP PLEASE
I'm not a pro either but all amps must have a gain level
sens is sensitivity also known as gain
Sweet now how about bass boost and low pass filter how can I do that.
bass booster is if u tune the bass on your head unit in the negatives then you boost the bass and listen for distortion, the low pass filter you look at the numbers on the amp and try to eye it to the Hz you trying to push. in other words just turn the low pass filter knob to the Hz you require, there are things on the market to help with those fine tuning now.
if you put gain level woth a multimeter over example yours 20V, your subwoofers will play on distortion and they will blow
yea i think thats will help u put on a lil more bass i cant stress this enough just lesson for distortion
You set your gain with a test tone and then you're gonna hook everything up and readjust your EQ, including the HZ frequency you used in the tone. Isn't that gonna throw off the rms voltage of 19.9 that you had and clip/distort the signal. Personally I would have set everything from 100 HZ and below(on your EQ) to flat or default instead of unplugging it. I also believe that your fade has to be centered when you're doing this. Anyways, good video, and like you I recently tuned my amp this way with the truck off. I need to go back and redo it with the truck on, lol.
thanks for the info bro yea i had to go back after the vid to do it with the car on lol, but with my new car im now going to buy the really things to tune the amp and EQ correctly
That's great man! I'm looking forward to seeing that on video. Yeah i'm going to retune my amp tomorrow and experiment with reversing the phase. Can't stop messing wih the damn system lol
u2bed91 oh OK sure u should put up a vid
Actually I have one or two of my system, but I'm not very good at making videos and the damn Iphone won't pick up the bass from my sub. It sounds very smooth and blends in nicely with the music, unlike others here that like to overpower the speakers.The video just doesn't do it justice and I don't have a real camera to take video.
No the sub will be just great. Only make sure u tune the amp right for ur speakers
Thank you i needed to know where to put the bass. neutral sounds good
How do you know it distorts at 24?
By listening
Hey I need some help if you could it would be greatly appreciated!
People are so pathetic. They dislike because you didn’t say the word treble. I can’t believe these people.
how do i tell what ohms im running at?
Put a multimeter to your speakes wires positive / negative and check with resistance setting on multimeter
You did it wrong... Its the RMS output of the amp x the speaker ohm load you are using squared. So it would be say 200 x 2 if the ohm of speaker you input is 2 ohm
They should match. So no he's not wrong.
I missed the bit where you have your load connected?? You know, a 2 ohm or 4 ohm load!!
the thing is, you CANNOT tune it 100% correctly without an oscope. The "chart" you speak of is more of a guideline than what he amp actually does, therefore it is inaccurate before you even start measuring anything. All amplifier boards are different and each one has a certain max ACV it can output before clipping, the chart doesnt account for these variances, meaning it is inaccurate
it's been proven multiple times that if you set gains with the car on but not running then once the car is running the output voltages will increase, only way to avoid that is having a filter that restricts it to a 12v system but most amps are designed to run their best at 14v, but either way its distortion that cooks speakers, i'm wishing i had an o-scope to actually set mine up properly, i didn't overload the speakers but they still cooked because this test doesn't account for clipping
yea u can just make sure u know what ohms ur using and tru RMS ur amp has and no probz bro
Turn your low pass filter to 80. Having it at 50 is ridiculous. 6th order bandpass enclosures have the smaller side tune higher than 50 hertz... that would be horrible for sound quality. I'm sure on the inside of the amplifier it has a second-order low-pass filter, therefore if it starts to roll off at 50 it's probably going to stop at around 80. And nothing else will come out of the subs. That means that those door speakers need to play 50 hurts very well to keep the bandwidth of the usable frequencies. What I'm saying is you're having to make your door speakers push 50 hertz to make up for the lost bass. Door speakers shouldn't play any lower than 80. That means between 50 and 80 you have missing frequencies. And the ones you do have are very low on the dB spectrum. Turn your low pass filter up to around 80. That's where it should be. That's where almost every one of them is.
If you're doing the math based on the specs on that sheet then you're gonna be way off regardless coz there is Nooo way on God's green earth does that Pyramid piece of shyt put out what it's rated. I guarandamntee if u put an O Scope to it you're clipping!
Congratulations, you played yourself...
Can't have self-contradictory statements there bud... It's either over or under, not both. And you don't get clipping from "under" powering it, so doing it by the numbers is fine if your argument is that it's "not" going to push RMS rating.
How the hell its 200x2 or 2000x2 , how is that possible? I mean it makes no sense that the same amp is rated at 200 or 2000w just a small difference. And why didn't you do the 2000x2 to get the full power if it's capable to 2000rms right or is it just 200 rms and 2000 who knows what
No the sub will be just great. Only make sure u tune the amp right
Cool! Thanx for the reply man. I ordered one from eBay today. It's coming from shenzhen so I should get it in about a month...lol.
Journey girl that sings all kind of wrong and I don't know Jack anyting about stereos explain why your setting things where you are setting them are all subwoofer supposed to be low pass filter that 50 hertz??
This is very hard to follow & the logic is not explained.
What exactly are we tuning for?
whats HPF? how do i tune that?
the HPF-(High Pass Filter) just tunes the speakers that are still hooked up to the head unit speaker wiring and you tune by ear
That power on your sheet was at 14.4 volts. You tuned the amp on 12.4 volts. Your capacitor gave it away.....
yea i for got to tune the car on the car must be on to do this correctly
It's because the vehicle is off. The alternator is not putting out 14.4 because it's not running
the RMS 14.4v into 2ohms= 800w on the manual means that the amp will give u 800w rms when the car is running @ 14.4v. ur car gives out that when u start it but when its off u'll get 12.4v or so the formula will work with the 800w by 1 im amusing........ the 40 is what ur looking for on the M.Meter when u turn ur gains up.
oh ok i c. well this is the way i do it for now and it haven't failed me yet i dont want to spend that much money on O-Scopes and shops. im not trying to go into sound a competition or anything like that lol and i buy certify amps that is trust worthy for there RMS rates.. sorry to hear that this method didnt work for u. check out the link in my description.
