HOW TO KNOW WHICH OHM LOAD TO USE?
HTML-код
- Опубликовано: 19 мар 2022
- Knowing the correct ohm load for your amplifiers is essential for the preservation of your amps and overall system. It is very easy to overheat and blow out an amplifier by not using the proper ohm loads. The correct setting depends on your amplifiers output power.
In this video, JP gives us a few tips on determining which ohm load is right for your system.

Curious question. I have a Mechman 320Amp Alternator running 5 XsPower D3100 batteries. It is okay that many batteries for the alternator to charged it up ? It looks fine on my two voltmeters 14.4 when is off and 13.8 to 14.0 running the system
Get a smart charger 🔌 so when you are parked it helps to keep them charged
I just wanna check. Driving a 17 sierra, wanting to replace stock speakers. No amp, stock head unit. Would 4ohm or 3ohm be better?
Can u tell me if a sony xplod 1000 xm 1652z amp is 1ohm thanks
I know there are different ways to set the gain on an amplifier. You can use oscilloscope, DD1, or multimeter. But if you use a multimeter, and use the square root of power times resistance, you get a different voltage on 2 ohms from 4 ohms. But if you use the DD1 or oscilloscope,you only have one gain setting. Does that make one of the methods wrong?
A bit late to the party, hope this'll still help.
I've been settings gains with a portable oscilloscope for years, from experience it's not the most accurate thing (For SQ purposes), if all you're doing is tuning as a daily then go for it, I recently picked up a DD1+, and a CC1, tuning has become much easier since I work on a bunch of amps weekly.
Just a rule of thumb I used was whenever tuning with an oscilloscope I just bump it down a hair just to be sure.
Good luck!
Can a pair (2) of Kicker Solobaric S12L7's 4dual 4 ohms drop to 1 Ohms?
I am wondering about sound quality. Will playing a sub at 2 ohm is a balance between 1 ohm and 4 ohm? My amplifier can do 1 ohm, but will that change the necessary power from my electrical system I have setup for 2 ohms? I ask because I like to take full advantage of my amplifiers overall power, but I don't want to have to be changing it out because the amplifier is under more stress. But again, I want more watts. Another question. Higher wattage like from 750-2000 require a lower ohm or can I get the same power at 2 ohm or 4 ohm. Doesn't have to be 1 ohm? I am new to car audio and trying to figure out what works best. Thanks
Don't run a 1ohm load. All the cheap amps like the one jp sells recommend using 1ohm. Then when it blows u come back for another one. Also you will be getting distortion with your bass note since you'll most likely be clipping. 2 ohm/4 ohm loads are best. Kicker amp
@@lilwinemane thanks
@@user-TurboD12 fasho_ kicker cxa-800 a good amp on stock electrical. With 2 12s or 15s. I'm runnin a sealed box so it plays everything smooth
@lilwinemane I will check that out. I have about $1500 to play with. Hopefully, I can find a decent setup with that. Thanks again.
I run 1 ohm on a sundown x8.
The jp95 seems to handle it just fine.
May go lower grade sub but a bigger diameter. Maybe not
Tht x8 is a 2.ohm speaker rght?
I have a kicker l7 12" on an American bass phantom 2500.1. It's rated 1250rms at 1ohm and it doesn't have any ratings for 2 or 4ohm. I'm wondering if i have enough power to run it at 4ohm would that be better Sq out the sub or does that not really matter?
I have 2 kicker L7 12 2ohm q class on a taramps 1800.1 d 1 ohm I'm trying to figure out if I should I wire them down to one ohm or should I just get the 2 ohm version of the 1800.1 taramps for the best performance? You know anything by chance?
I need some help with my subs. I bought 2 X10 v3’s dvc 2ohm each. Can u help me out on how to wire them and what would be the proper amp for it. I appreciate the help from anybody that understands on how to hook them up thanks
I just stepped down my system for the sake of trunk space from x2 12's on a RP 1200.1d and bought a NVX vc series 8" with a Skar armored box. Now question is to run it at 4 ohms and feed this 650 rms underrated sub 500 watts probably more like 580 or go for 1ohm and feed it the full 1200 probably more like 1300 to 1400 @12.5v, now i do realize i need to back the amp off quiet a bit but what should i do here? I will upgrade the amp when i can afford it to the JP95 x5 channel but can't right yet i think the 700 watt mode of that amp will be perfect for this sub and a much needed upgrade for my highs.
Hey which is a better setup? A 2x2ohm sub with 1ohm amplifier in series or 1x1ohm sub with 2ohm amplifier in parallel? At the same power.
I have a Rockford Fosgate p2 10 that I bought wired at 8 ohms. Should I wire it to 2 ohms and would it be louder?
I got p212s8 !
Could you run 4, 6.5, 4 ohms door speakers down to one ohm parallel and it work and sound clear? Or would it stress the speakers or amp?
Amplifier only cares about final load ( impedance )
If your amplifier is rated to go down to 1 ohm you can safely
run four 4ohm down to 1ohm
or eight 8ohm down to 1ohm
@@Dauntless.steadfast.fortitudewould it make the sound quality, etc etc sound different ?
Best way to wire 2- dual 4ohms 10" cvx.
2ohms or 8ohms/ parallel or series on a Sundown SIA 2500d amp?
2 ohms. and find an amp that can exceed what your subs put out RMS @ 2-ohm
So I have a Sundown sa 12 v2 in a ported box tuned to 36 hz and I’m currently on stock 8 gauge wire would anyone recommend to run 0 gauge wiring ?
Definitely 0 G Or maybe 2 G at smallest.
With that 8 G your using you can’t deliver the proper power to that sub .
If it was brand new it was probably ok that you did that.
Considering when a sub is new there is a break in process.
But it still probably needed much more power .
To properly break it in before you really start pushing that sub harder.
I don’t know if you ever got your answer but that should definitely help you.
I have been installing systems for 30+ plus years now.
So I definitely know my way around Amps and subs and systems.
I still learn new stuff all the time.
Things change so much with amps and subs I learn something new daily.
Hope everything goes good for you have a wonderful day.
Also just remember when you up the wire just make sure you put a big enough in line fuse to protect the Amp.
What ever size Amp u use the minimum size fuse that you can use will protect your amp the best.
So many people put a huge Fuse by there battery if it’s to big your not protecting the Amp or the car or anything for that matter.
Because it will not blow the fuse quick enough.
Also or it might not blow at all and could definitely cause a fire definitely possible.

How to hook you 2 12 dual 2 ohm n 2 12 dual 4 ohm to a half ohm stabel amp need help
Can 2 - 12" 4ohm DVC subs be wired together outside the box when in Parallel for 1 ohm load total? For example 2 subs in its each sealed chamber. 1 wire coming out each chamber put together to the amp.
Yes, wiring everything parallel, you can even check with a multimeter, the final impedance should be 1 ohm load. Some ppl run the wires out the box just for amplifier flexibility in case they swap it for a different spec one later
@@stevelovesgod Thank you!
Could you help me out? I have two 2ohm Skar EVL 12’s on a 2700.1 NVX amp. Could I run them at 1 ohm or only .5ohm? And if I run at .5ohm will it hurt the subs?
You can only wire them at o.5ohm, 2ohm, 4ohm, not 1 ohm
How's the bass build going? Hopefully it's still going good with the situation over there.
If I wire 1 sub to 0.5 ohm will the amp see 0.5ohm??
how does bridging work on 2 channel amps. one of my bros friend ask me to hook it up. its 2 ohm stable and when i hook up the sub at 2ohms the amp goes in protect but when i hook it up regular it works fine but its under powered. i told him to buy a class d lol but hes a kid so hes broke
Maybe it's not a bridgeable amp.
It should say on the amp were you connected the speaker wire.
2ohm stable in stereo generally equals 4ohm stable bridged.
@@gakudzu7282 I don't know what that means. im not familiar with them
@@rowboyto156 Bridging is just what it sounds like. Creating a bridge between the channels to combine their power. If an amp is bridgeable it will have it shown somewhere around the speaker output as to which channels to use as bridge. Generally its the 1st channels positive and the 2nd channels negative. Its essentially the same thing wiring batteries in series for more voltage. If an amp isn't clearly designated as bridgeable on the outputs I wouldn't bother.
Like wiring a sub in parallel bridging the amp cuts the ohm load in half. I've run 2 dual 4's (1/2 ohm) on an old Rockford rated at 4 ohms bridged with no problem. I've also had a cheap Walmart amp go into protect with a single d4 on it, so it really depends on the amp
Was this an add for Sundown? I didn't see any how-to!

Any pioneer head unit will be good
@@chrisfiske my exact reply
Alpine is my favorite brand for car stereos. Always wanted to try a Pioneer thought
A lot of brands are good but pioneer is clean at almost max volume I run JVC myself and out of volume 35 I can only use up to 28 and be clean... pioneer has it figured out but anything will work just keep the signal clean is the main goal and be loud..🔊🔊
Jvc has 5 volt pre out.
Pioneer seems to be a go to for bass heads.
Apparently they have a synthesizer in the settings

Still haven't answered the question on the d4s lto battery that I put out about 2 weeks ago
probably because there's multiple videos on the channel that could answer any questions about the battery. Hes not gonna answer a question that's been answered because you wont do the research.
Might want to ask your question on one of tha other platforms. RUclips doesn't really get as many responses as others
Thanks! Less ohm = more power
so what im understanding is 2ohm is for single sub setups and 4 is for multiple subs since it will take less power the amp leaving some for the other sub
The answer is always 1ohm lol. For me anyways.
I'm wit ya
I'm with you also lol.
I saw this amp that was 0.5 ohm stable lol. I was like nah I won't risk it.
Depends on what type of music and how sharp you want the subs.
4ohm gives the amp/sub a great control.
Lower the ohm load, the less control the amp has on the sub.
Yes it’s loud, but not as sharp.
Not sure how many people actually understand what the give/take relationship is.
For every action there is a reaction
I messed around and got 4 subs dual 2ohm instead of dual 4ohm. Does that mean that I'll have to run my Amp @0.5 ohm to get max out of it....🤔
Pretty much
What is your amp?
@@yhprumhsoj 2 Crescendo 6k
I don't know what your electrical is like but if it was me I would run them at .5
Yup. That amp can handle it though. Make sure you have great electrical first. HO 300 amp plus alternator, large enough wire and battery back up. Sky high 1/0 is great.
What is the point a low ohm system vs a 4ohm system?
Basically, smaller impedance (ohm) gives you more power at the speaker.
The same amp will give you 300w @ 4ohm or 1,200 watts @ 1ohm.
Now, the lower impedance the easier it is for you to blow your amp since things get more delicate
@@skobeats exactly, what's the point? Stop being a poor and buy the proper sized amp.
I'm looking for a technical reason, efficiency, better motor control...
I Have a question?
I like how we’re given a number to call if we have questions yet I just called and they told me to send an email.

Bros jus chattin
Video doesn’t talk about “How to” at all
Word 😂
1 minute in, and he's already using industry slang. Why bother doing an explanation video.
U talk too much without benefit
Rule of thumb. Lower ohm load lower the bass.. higher ohm load it gets to be more punchy and higher bass and that tends to be good for that high bass and id recommend using 10s and 8s for that higher ohm load.
I have two 12’s should I use 4ohm
