Nice video! You did a great job explaining our LC7i, and your detail on setting the gains was well done, too. Thanks for helping other car audio enthusiasts with your videos!
@@PeterFeltersnatch852 I have 2 different kicker loc's... and I want to use my Kicker Front Row DSP... and 3 amps... 1 bass... 1 mid... 1 tweeters... all kicker... even wires... battery mounts... you name it ... kicker... except cooling... that is 4 fans running off SMD control temperature gage..
I really liked this explanation. It’s probably the best I’ve ever seen. No useless info No stuttering No second guessing the info you already gave No nerdy squeaky voice Good pace Good authenticity in your knowledge. I think, if everybody made videos like this, instead of trying to appear smart and putting on a ridiculous “high energy” persona, the world would be a better educated place. I’m going to sub and hopefully you will make some additional car stereo videos. Suggested video: Setting with oscilloscope. ;)
I'm an electronics engineer with a small background in analog amplifiers and a life long passion for music and mobile audio. I've been installing audio equipment and setting gains by ear for 25 years. While that has worked pretty well I was blown away by your simple explanation and I'm humbled. Thank you!
That’s what I thought also. I checked multiple sources and it’s the same process. Problem I ran across was that the volume to the sub was WAY off!!! I set the highs and Mids with my ear and it’s perfect. Doesn’t matter what I do the sun is just low. I simply went back to the old school ear method and the sun came alive
Setting the gains like in this video is fine as long as you leave the eq flat and tone levels at minimum. If you set your gains with everything flat and as soon as you start making eq adjustments or bass adjustments now you'll be clipping. Ask me how I know.
@@mattburgess2 you just contradicted yourself. the second half of your statement is correct, as to why you want to set EQ before gain. Everything is set before gain.
one question just to make sure: Amplified voltage at a bass frequency, is the square root calculation made by using RMS or max voltage of the sub? you said in the video "max rms".
You explained everything perfectly and easily understandable.. I haven't come across another tutorial that strictly sticks to the task of what most people came here for. 👍
Wow, this video is very well done. I like that you took the time to pull the seat for the visual aid instead of just using a screen share of your computer. And even though I watched the whole thing, I always appreciate time stamps. The links are a really nice touch!
Bro, thanks for teaching us a detailed and simple way to make this work. I’m new to installing car audio but I’m very smart and fast at learning. Thank you for this.
GREAT video…thanks for posting! 🤙 Everything you said was easy to understand and made a lot of sense. Being new to car audio, I’m just learning this stuff and really appreciate videos like this. Cheers man 🍻
This is by far the best video i have seen on how to set gain. Not only do you cover everything, but you've made it so easy to understand... So happy i came accross this video before I tuned my amp.... If i had gone with the knowledge of other videos i would have been missing a few tricks and certainly not maximised the potential of my setup.. Thank you very much, you've earnt a subscriber !
I do not see how this video has any"thumbs down". This was very detailed and informative. My question is this, if you have a head unit that has "subwoofer level", I was told it affects the input voltage to the amplifier from the head unit. Is this true? And how would you set the amps gain without the line convertor.
Best information ever! -5db makes the most sense. I've been struggling to get the output I wanted at lower levels! I'll give this a try this weekend. Thanks!
I’ve watched a LOT of videos on this. Yours was the most clearly explained - with good tips and tricks, especially the raw-wire RCA to voltmeter method. Thank you for posting. Subscribed here, and will be sharing your video to whoever might want it. Have a great day!
Agreed. I have been trying to understand how this all works and I feel more RUclips creators are more concerned with keeping their secrets a secret or showing off their shop tools that do not make sense for me to buy as a hobbyist. This video was the absolute best quality and most understandable presentation I have seen yet.
One of the best step by step system tune videos on youtube thank you so much! I will subscribe. P.S. I'm 99% sure on RF amps the bass nob dose not control the gain maybe on the Prime but on the Punch and T. The bass nob it is a set 45hz DB volume adj. it IS the punch EQ! also on RF as soon as you plug in the remote bass nob it bypasses the punch EQ on the amp because you are now controlling it remotely. If it has changed that's news to me.. I have two T1500 and a bunch of punch amps new and old.
This helped me tune my system in and definitely made me feel more confident that I’m not going to blow any of my speakers or amps! This is my first time having a set up like this! Thank you 🙏 I used Kicker U for wiring and tone generation!
This video is the BEST teaching of how to set gains, that I have found on RUclips. I've spent days/weeks looking at examples of how to set gains correctly with my LC7i and this video is by far the best! Thank you so much for the clear direction and explanation. One question - what did you use to keep the leads from the RCA cable to your multimeter? I'm going to install my LC7i this weekend and will use your method.
So I have a Question. If i Have 2 4ohm dual voice coil subs that handle 600 wats rms, and i am doing a 1 ohm load. I get the calcualtion and all, jus wondering if my amp is 1200 watts rms at 1 ohm load, when i do the calculation, do I do the square root of 1200 X 1 or the Square root of 600 X 1.
Excellent video! Very detailed but concise, I’ve always flubbed around with these settings. I’m going to tear into my system this weekend and fine tune everything. Thanks for putting this together!
I had my amps under the seat on my wrx still too, but there is also a heater duct under there spraying warm air so have moved them into the boot. If you want a decent, but well priced head unit with dsp, secaine make one that fits into these cars. Good video though and some well explained points,thanks
This video ABSOLUTELY answered my question to you on your other video where you apply the LC2i (i.e., asked about the sequence of setting Gains). Main takeaway for me was to assemble the proper equipment and information in order to follow the sequence and perform this procedure correctly. Know/have: 1) a Multimeter 2) Know both your Low Level (i.e., RCA) and High (i.e., speaker high-level) input ranges for your devices in play ... here the LC2i, Alpine amp and other Amp (don't recall the name) so you can apply the multimeter with the test tones 3) Know the RMS for your amps and ohm load so you can apply Ohms Law to calculate Gains 3) Speaker frequency ranges so you can set HPF (if relevant) Thanks and Great Channel
Question. What if I'm using a Epicenter in between the Lc7i and Monoblock? Do I send the recommended voltage for only the Epicenter? And would that lower my signal output overall to sub amp instead of sending recommended output voltage to directly to the Monoblock.
Just take note if you set your EQ flat and set your target voltage it will change if you turn the bass EQ up any at same volume and will have to adjust again.
I totally agree! I don't understand why 99% of literature and videos tell a person to zero/flatten their treble and bass settings on their head-unit only to have their set target voltage on their amps go too high because they later turned their treble and bass settings back up on their head-unit afterward??? ...then a person has to go back and lower the gain/voltage on their amps because it went way too high at that same 3/4+ volume.
Best video out there. I’ve done installs over the years for family and friends and your content is spot on. Very helpful and straight to the point. Thank you for saving me time and money.
A trick I used when tuning my competition stereo back in the day was to put my fingers in my ears or use hearing protection earmuffs. You can make out distortion a lot easier if you do this.
Man I was thinking the same thing.Is that alpine amp really screwed into the top of that prime 500? Thats about where all the mosfets are mounted inside around the outside edge🤣
Very nice wire management. Excellent explanation. I have not been using the -5db test and setting up at full volume to see an end result of low RMS output, incorrect tuning. Thanks for the video. Will try this method as it is more real world tuning at listening volume of 75% and the source db levels. Appreciated.
I usually set my gains with a 0dB sine tone as I listen to a lot of non-mainstream trap/EDM. Is there something I can use to figure out what the maximum dB is of songs that I listen to, or can you recommend a dB sine tone I should use for my requirements? I know in your video you mentioned -5dB but I'm not sure if this might be too much or too little but I'm really looking to maximize my gains. Thanks so much!
freakin awesome most helpful and explanatory video. thank you! however i am stuck at one major step. So i bought a multimeter just last night since i am worried that my amp or sub getting damage because of the current gain setting. i went ahead and straigh up tried setting the gains
but after hooking up the multimeter to the speaker outputs of the amp to set the gain...there is a 0.00 readind and does not change from there? everything its good as far as the other steps. test tone. hu volume...but no multimeter reading after hooking it up to the amp? help me.out brother. thanks...
I have a lc7i pro mono gain set with multimeter bass sound good but plays really low as in volume when I turn gain up a bit hits really hard but then I get a knocking bass not the low deep bass amp is power fosgate 1bdcp 500x1 ran at 1ohm sub is one T1 d212 2ohm dvc I got a 4 channel amp highs are good just can’t seem to get low deep bass
Love how easy U made that but I have a kicker comp cxa 800.1 amp and it has two additional knobs!! Do I repeat the process of the gain knob or is their a different method???
Quick side question - You mentioned in first calibration to put everything to flat .. if however one likes a bigger bass curve or brighter highs, shouldn’t we set the system “the way [we] like it” beforehand, so that if you DID boost frequencies, they wouldn’t overload or distort the LOC or other devices? Or is the 75 percent suggestion enough of a swing to compensate for any overdriving? Thank ya 🙏
hi i need help my amp says LOW PASS FILTER 50-250 is this a good or bad amp? and can it hit below 50hz? this is a 4000 watt planet audio? some amps says 20hz or 30hz LPF ... please explain detailed, i guess what im really asking is can this amp hit 30hz or 35hz ?
I also use this line out converter, but with a rockford fosgate 4-channel amp. I have an issue with alternator whine, but it's only present when i touch the gain on the amp. Right now i have the gain on the amp set to 0, but if i touch it at all, i'll get a very prominent alternator whine through the speakers and i have no idea how to get rid of it.
Hope you respond! I need help. JD1000.1 pushing 15" Kicker CVX, with LC2i 1000 x 2 = 2000. sqrt2000 = ~44.7 = target voltage So I: -75% volume 50hz test tone -Set LC2i just a hair before 'maximized' light turns on. -Amp gain all the way down still reads about 56, higher than voltage. (ALSO - do I set inputs to low level when running from LC2i? - is this where my issue lies?) BUT, if I set gain to hit the clipping indicator light on the amp itself, the voltage reaches like 75. As of now, it sounds way underpowered. I had a 12" with 400 watts and that was louder. I'm not sure what I'm doing wrong and what I'm missing. A little confused why these two numbers would be vastly different - target voltage v. clipping light voltage.
So I have always had trouble setting gains as I just can't hear distortion and I tried to hook up my system using this method. For whatever reason I got no sound from the speakers once I hooked everything up. I ran 1 set of wires from the head unit for a FL/FR and then ran 2 sets of wires from the amp back to the wires going to the speakers. Not sure if it is the harness (CRUX toyota harness) or what. I wound up having to switch back to using rcas and the sound worked. Otherwise it was a great tutorial and if it would have worked it would be been great lol.
Thank you so much man, I have the lci7 as well with a sub and speaker amp. I’m getting so much distortion so I’m going to try this myself because the shop I got it done at couldn’t figure it out. QUESTION: will having a stock stereo mean I may still have distortion? And what song should I play for the speakers? Does it matter as long as it’s high end quality. I have heavy hip hop songs then some Weeknd songs that have a lot of high frequency parts
I can install wiring, speakers, subs, head units you name it but when it comes to setting gains and all that I really have no clue on what I'm doing. I don't understand frequencies and hertz or any of that. I learned how to set with an oscilloscope but I wonder how well it is cause I feel like the bass just doesn't hit as hard. For bass I used a 40hz test tone but I'm not sure what to use for mids and highs.
I set my amp gains by a simple multi meter on 2 ohms only my amp can do 1 ohm's but since I am aiming for efficiency up to clipping on my one subwoofer. A person CAN NOT do this with a SMD DD-1 and try to overlap the gain on the amp where the micro processor on ANY CAR AMP can not do :D LOL
I did all this and actually my input voltage was starting at 12 volts!!! Anyway I set my Kicker Amp for 48 volts for a 4 ohm load for one 8” Kicker Q Class. Get this after all that the sun still played low. Didn’t matter what I did. Eventually I just brought up the gain ever so slightly and the sub came to life. I did it twice and it’s the same. My other amps play fine. But I did set them by ear and they sound great. Any suggestions?
to dumb things down, should my equalizer settings on my radio be set to normal (neutral) before i tune my amp? i dont have all this fancy stuff, just a stock radio on a does f150 and a basic amp for my subs. and if i do need to set the settings to normal before i tune my sub, i can turn them back up once the amp is tuned, correct?
Can you do a video tuning a LC2i Pro with a Alpine S-A60M and a Subwoofer S-SB12V ?, that's my setup and it would be nice if you teach us how tune it, BTY, my car is a 2017 Honda Accord EX-L V6 with factory Subwoofer, Thank you!
Boost & Shutter i'm watching you make the gain adjustments on the Alpine KTA-450 amp how far do you have the gains turned up on the front and rear gains, it looks like about half way if i'm correct?
up to the maximum where it doesn't produce distortion or until it delivers the right power level to your speakers. sets the gain to the lower of the two. Voltage=√(power×impedance)
Sorry for my ignorance but, is it the sensitivity volts that I'm looking for? I'm going to do my own install and I want to make sure I'm doing it right. I'm using these two, Prime 500 Watt Class-D Mono Amplifier R500X1D (I think it's 4V max) and Prime 500 Watt 4-Channel Amplifier R2-500X4 (I think it's 12V max for highs). Can I get advice so I don't jack this up and waste the little money I have lol? Thank you
First of all. Fantastic video and easy to follow. I do have technical question. So, I have a 1500.1d amp and pushing 800 watts at 2 ohms. But I know some of that power is lost to heat. Does this mean I should increase my amplifiers sensitivity a bit more to compensate for that loss?
I set my sub amp up with the speaker connected, using an oscilloscope (which is a better method than using just a DMM). I've read that this is more accurate, as you're measuring the signal when the voltage rails are actually loaded to account for voltage drop. Barevids has a video on this. I also do this with the car running, so it's providing the full 14.4-14.6 volts supplied by the alternator. I should also state, that my sub is capable of handling more RMS than my amp can put out.
The individuals that gave this video a thumbs down must have had a bad day. This was the easiest and simplest explanation yet, here on RUclips. GREAT VIDEO!!👊🏼
Im buying a 2020 Accord with the premium system, im going to tap the back speakers, and merge the signal into 1 channel, then use a distribution block for 6 rca ports, then use those 3 sets for 3 equalizers to amps, my question is do play test tones with all speakers disconnected?
No disconnect all speakers and connect the speakers u plan on tuning for example front channels 1 and 2 disconnect 3 and 4 only set the gains on 1 and 2 but you’ll probably have to do this individually but you will want the same outcome out of both not two different frequencies

Thanks for watching
This was perfect. Nice one. Now, is there an equally easy way to know you've set your crossover points correctly?
Don't set gains by ear. You're hard clipping the amp long before you can hear any distortion. An oscilloscope or DD-1/DD-1+ will easily verify this.
Excellent video, I learned a lot. Thanks for posting!
Great video on how to set your Lc7i, thank you.
Where did you get your 4V info from? How do you find out how many volts your amp maxes out at? I can’t find that out anywhere on my Kicker 44KXA800.1.
Very good explanation of gain setting. Thank you
This helped me tune my system in and definitely made me feel more confident that I’m not going to blow any of my speakers or amps! This is my first time having a set up like this! Thank you 🙏

Awesome and professional YT channel btw!! Def one of my new fav car audio channels! (LC7i Qs brought me here)
So professionals screw amps INTO other amps??
Question. What if I'm using a Epicenter in between the Lc7i and Monoblock? Do I send the recommended voltage for only the Epicenter? And would that lower my signal output overall to sub amp instead of sending recommended output voltage to directly to the Monoblock.
That auto gain is not a thing yet is mind blowing to me

Just take note if you set your EQ flat and set your target voltage it will change if you turn the bass EQ up any at same volume and will have to adjust again.

No room? Screw your amps together 😜
I was thinking Velcro was better
Man I was thinking the same thing.Is that alpine amp really screwed into the top of that prime 500? Thats about where all the mosfets are mounted inside around the outside edge🤣
I chose to set my gains at 50% volume because stock head units can roll off the bass at higher volume to prevent damage to stock speakers.
This was freaking Awesomesauce! Thank You!!! Cheers!
Great Video, so much information. I have a question though, why do quite a few people put there volume at 75%?
75% gives you overlap and for modern head units it should be well before you start introducing distortion.
Very nice wire management. Excellent explanation. I have not been using the -5db test and setting up at full volume to see an end result of low RMS output, incorrect tuning. Thanks for the video.

but after hooking up the multimeter to the speaker outputs of the amp to set the gain...there is a 0.00 readind and does not change from there? everything its good as far as the other steps. test tone. hu volume...but no multimeter reading after hooking it up to the amp? help me.out brother. thanks...
What’s the difference between that audio control LC7 and the regular epicenter?
I have a lc7i pro mono gain set with multimeter bass sound good but plays really low as in volume when I turn gain up a bit hits really hard but then I get a knocking bass not the low deep bass amp is power fosgate 1bdcp 500x1 ran at 1ohm sub is one T1 d212 2ohm dvc I got a 4 channel amp highs are good just can’t seem to get low deep bass
Love how easy U made that but I have a kicker comp cxa 800.1 amp and it has two additional knobs!! Do I repeat the process of the gain knob or is their a different method???
Quick side question - You mentioned in first calibration to put everything to flat .. if however one likes a bigger bass curve or brighter highs, shouldn’t we set the system “the way [we] like it” beforehand, so that if you DID boost frequencies, they wouldn’t overload or distort the LOC or other devices? Or is the 75 percent suggestion enough of a swing to compensate for any overdriving? Thank ya 🙏
When you removed your passengers seat, then reinstalled it, how did you make the SRS/Airbag light go away? After you plugged it back in?
Take the ground off the battery before you unplug your air bags. Than after you put them back. Attach the negative back on battery
hi i need help my amp says LOW PASS FILTER 50-250 is this a good or bad amp? and can it hit below 50hz? this is a 4000 watt planet audio? some amps says 20hz or 30hz LPF ... please explain detailed, i guess what im really asking is can this amp hit 30hz or 35hz ?
I also use this line out converter, but with a rockford fosgate 4-channel amp. I have an issue with alternator whine, but it's only present when i touch the gain on the amp. Right now i have the gain on the amp set to 0, but if i touch it at all, i'll get a very prominent alternator whine through the speakers and i have no idea how to get rid of it.
Hope you respond! I need help.
JD1000.1 pushing 15" Kicker CVX, with LC2i
1000 x 2 = 2000.
sqrt2000 = ~44.7 = target voltage
So I:
-75% volume 50hz test tone
-Set LC2i just a hair before 'maximized' light turns on.
-Amp gain all the way down still reads about 56, higher than voltage.
(ALSO - do I set inputs to low level when running from LC2i? - is this where my issue lies?)
BUT, if I set gain to hit the clipping indicator light on the amp itself, the voltage reaches like 75.
As of now, it sounds way underpowered. I had a 12" with 400 watts and that was louder. I'm not sure what I'm doing wrong and what I'm missing.
A little confused why these two numbers would be vastly different - target voltage v. clipping light voltage.
So I have always had trouble setting gains as I just can't hear distortion and I tried to hook up my system using this method.
For whatever reason I got no sound from the speakers once I hooked everything up.
I ran 1 set of wires from the head unit for a FL/FR and then ran 2 sets of wires from the amp back to the wires going to the speakers.
Not sure if it is the harness (CRUX toyota harness) or what. I wound up having to switch back to using rcas and the sound worked.
Otherwise it was a great tutorial and if it would have worked it would be been great lol.
What If you have a subwoofer with built in amp and don't have access to the wire leads going from amp to subwoofer
Is it ok to run a 50hz -5DB test tone through your car speakers while doing the gain setting?
Thank you so much man, I have the lci7 as well with a sub and speaker amp. I’m getting so much distortion so I’m going to try this myself because the shop I got it done at couldn’t figure it out. QUESTION: will having a stock stereo mean I may still have distortion? And what song should I play for the speakers? Does it matter as long as it’s high end quality. I have heavy hip hop songs then some Weeknd songs that have a lot of high frequency parts
I can install wiring, speakers, subs, head units you name it but when it comes to setting gains and all that I really have no clue on what I'm doing. I don't understand frequencies and hertz or any of that.
I learned how to set with an oscilloscope but I wonder how well it is cause I feel like the bass just doesn't hit as hard. For bass I used a 40hz test tone but I'm not sure what to use for mids and highs.
How hot your amps get? I am running a LC2i and my amps get pretty hot
I set my amp gains by a simple multi meter on 2 ohms only my amp can do 1 ohm's but since I am aiming for efficiency up to clipping on my one subwoofer. A person CAN NOT do this with a SMD DD-1 and try to overlap the gain on the amp where the micro processor on ANY CAR AMP can not do :D LOL
I did all this and actually my input voltage was starting at 12 volts!!! Anyway I set my Kicker Amp for 48 volts for a 4 ohm load for one 8” Kicker Q Class. Get this after all that the sun still played low. Didn’t matter what I did. Eventually I just brought up the gain ever so slightly and the sub came to life. I did it twice and it’s the same. My other amps play fine. But I did set them by ear and they sound great. Any suggestions?
to dumb things down, should my equalizer settings on my radio be set to normal (neutral) before i tune my amp? i dont have all this fancy stuff, just a stock radio on a does f150 and a basic amp for my subs. and if i do need to set the settings to normal before i tune my sub, i can turn them back up once the amp is tuned, correct?
Can you do a video tuning a LC2i Pro with a Alpine S-A60M and a Subwoofer S-SB12V ?, that's my setup and it would be nice if you teach us how tune it, BTY, my car is a 2017 Honda Accord EX-L V6 with factory Subwoofer,
Thank you!
I wished you lived near me.
Boost & Shutter i'm watching you make the gain adjustments on the Alpine KTA-450 amp how far do you have the gains turned up on the front and rear gains, it looks like about half way if i'm correct?
up to the maximum where it doesn't produce distortion or until it delivers the right power level to your speakers. sets the gain to the lower of the two.
Voltage=√(power×impedance)
Sorry for my ignorance but, is it the sensitivity volts that I'm looking for? I'm going to do my own install and I want to make sure I'm doing it right. I'm using these two, Prime 500 Watt Class-D Mono Amplifier R500X1D (I think it's 4V max) and Prime 500 Watt 4-Channel Amplifier
R2-500X4 (I think it's 12V max for highs). Can I get advice so I don't jack this up and waste the little money I have lol? Thank you
If you feed the amp the maximum voltage in can take in the line inputs, wouldn't you automatically have to put the amp gain in the lowest setting?
Great teacher! Thank you for taking the time to explain. Loving and learning from these tutorials.
First of all. Fantastic video and easy to follow.
I do have technical question. So, I have a 1500.1d amp and pushing 800 watts at 2 ohms. But I know some of that power is lost to heat. Does this mean I should increase my amplifiers sensitivity a bit more to compensate for that loss?
I set my sub amp up with the speaker connected, using an oscilloscope (which is a better method than using just a DMM). I've read that this is more accurate, as you're measuring the signal when the voltage rails are actually loaded to account for voltage drop. Barevids has a video on this. I also do this with the car running, so it's providing the full 14.4-14.6 volts supplied by the alternator. I should also state, that my sub is capable of handling more RMS than my amp can put out.
So if I only play 320 kbps music, should I tune at 0dB or -5dB?
The individuals that gave this video a thumbs down must have had a bad day. This was the easiest and simplest explanation yet, here on RUclips. GREAT VIDEO!!👊🏼
I appreciate that!
Aun que conecte solo en las 4 entradas(bocinas), los pares del canal de sub osea las salidas RCA me quedan funcional?
Im buying a 2020 Accord with the premium system, im going to tap the back speakers, and merge the signal into 1 channel, then use a distribution block for 6 rca ports, then use those 3 sets for 3 equalizers to amps, my question is do play test tones with all speakers disconnected?
No disconnect all speakers and connect the speakers u plan on tuning for example front channels 1 and 2 disconnect 3 and 4 only set the gains on 1 and 2 but you’ll probably have to do this individually but you will want the same outcome out of both not two different frequencies
If Im sending 2 channels from Lc7i to 4chan and the 4chan is recommended 5v for RCA Input. Do I split the voltage to 2.5v or do I set both at 5v?
