Amp getting stupidly hot.

If an amp is getting hot at its intended ohm load with correctly set gain its a crappy amp.

Having more power than you need is due to impedance rise and clipping.

Yeah but this has happened to me b4.. Running 2 sub equal to what the amp gives an it gets hot quick.. Removed one an it ran cool.

Then that sounds like user error....you prob ran the amp a lower ohm load than it could handle. Lower ohm load=amp gets hotter quicker.

This. So many people overlook it.

Okay you may be 100% correct.. But I took every single piece of advice you guys gave me... Those 2 BC (1700rms) made that T1500 hot. So I took em out an replaced then with a T2D2 12... And it runs cool not even warm @ 1ohm...but he should give it a go an see if it geta hot with one sub. If I'm wrong I'm wrong.

Read my mind.

Cmon mate...surely I'm not doubted that much.

Well until you've actually been into this game awhile, done own installs, diy sub enclosure builds, etc...its bound to happen

That's dumb. I ran a 1000watt Memphis amp to my 4 2500rms woofers and it never got hot and shut off.

I agree Remember when I was putting mine together and I ran ppi 1000 on my Two 18 Teams 5000 watts each and that little amp never got hot.

Well I am fresh when it comes to builds... I'v built 6 enclosures so far. As far as installs Iv lost count. Always used 0GA OFC on every install power and ground OGA terminals always bolted onto chassis each in seperate locations never together. Had plenty over heating issues even though amp is fully capable, but I did begin to realise alpines overheat excessively after joining these audio forums. As for ohm outputs I always DMM my ohms b4 testing.. Always! But then also with some brand subs their underrated an some do push out more than stated. And this I did not read so where in a forum I'v learned much through trial an error.

I'm using audiopipe wire for both gauges and online it says it's OFC. Also i have a voltage meter so I'm able to test the ground but the video @jerryltowlt posted said to hook to the ground side of battery then your amp ground but my battery is in the front of the car so i dont think ill be able to reach my amp ground so is there another way? Also I'll post a pic of the wiring diagram that used used when I bridged them. And @BOOMINGRANDPA if I run one channel per I'm only getting 300 rms to each sub which is why I bridged them so I'm getting full power.

No... Just no! The amp ran cooler with one sub because now you are at a higher impedance lol. You go from 1 ohm to 2 ohm and of course the amp will run cooler, it will also be putting out about half the power. It's running cooler because there isn't as much energy running through the components. But if you are wired at a certain impedance it literally does not matter what sub are there, the amp will produce the power at that impedance.

The subs do not ask for any power, they are a part of the circuit and they allow power. If you have subs wired at 1ohm, it doesn't matter what subs they are, they amp will produce the power it is supposed to at 1ohm.

yes u will get less power in stereo but sorry 99% of 2 4 6 channel amps are not designed to run a 2 ohm bridged load.. so run it in stereo for now until u can get a mono preferably 1ohm stable amp so u don't have these problems in the future.. some guys here do run ground all the way to battery i've never done it that way.. find a good spot pretty close to amp make sure it's sanded down well before u bolt it down.. if u re wire the subs/ amp i'm 99% sure your problem will go away..

well if subs are 4ohm dvc and u have it bridged thats not the problem (though they were 4 ohm svc) could be messed up sub too though.. just make sure your ground wire is as thick as power wire and if u over 500 rms has to be at least 4 ga..

The subs are DVC 4ohm and the amp is stable at 4ohm bridged which is how I have it wired. But the amp only has 4 gauge power & ground leads so I have 4 gauge going the the amp to the cap then 1/0 from the cap to chassis. I'm gonna get rid of the cap soon and get distro blocks and redo my found better and see what happens. But the thing is I dont get why all this started happening once I put the 250amp alternator in...

sounds like u may just need bigger power wire
