Re: Amp overheating

Wire size depends on source, not load capability. your amp can provide 500 watts, so gage should be about 8, provided your speakers are 2 ohms each... you can measure them with ohmmeter. If you have 4 or 8 ohm speakers, you should get impedance matching transformers. Also, you should use a supply capacitor on power feed to amp of about 10 Farads...these are large and not cheap, but they provide "backup" power for heavy bass loads.

Hot Amp!!!

I'm having trouble visualizing exactly how you have it set up. You said that the amps are "grounded through the amp" but I think you meant they're grounded through the cap. I don't think that's the cause of your problem, but the cap and amplifiers really should be grounded separately. There's no reason to run the grounds to the cap instead of directly to the chassis. It seems more likely to me that the problem is related to your speaker wiring. I'm not clear on how your speakers are wired either; I can see that you've kept the speakers on factory wiring, and connected the amp to the factory wires. But I don't understand how that translates to having only one set of wires for both speaker sets. We'll leave the tweeters out of it; if they're wired through a crossover, then they don't have a serious effect on the impedance. However, any way you look at it, you've got two 4-ohm speakers wired together to a bridged amplifier. Most 2-channel amps aren't designed to be connected to load impedance under 4 ohms when they're in bridged mode. If your speakers are wired in parallel, then the load impedance at the amp is 2 ohms. Having too low a load impedance is the most common cause of amplifier overheating. My advice is to re-wire the speakers so that one 5x7 and one tweeter (together with a crossover) is connected to each amplifier channel. Don't run the amp in bridged mode. Even in this configuration, I'd be amazed if your 5x7" speakers are really rated to handle 310 watts RMS, which is the per-channel power rating of your amp in 2-channel, 4-ohm mode. It sounds to me like you've got too big of an amp for the job.

I installed a planet audio TW402 amp in my car. i put this amp last summer. when i first put it in my car with an sony xplod sub. i had a very small 12 gauge power wire and ground wire. but still it worked...

It could have to do with how your speakers are wired. If you have 2- 4 ohm speakers and they
are both wired to one terminal (RIGHT OR LEFT) on the amp, you have a 2 ohm load and most amps are rated at 4 ohms.
Go to this site and use #58 on the right sidebar to see if you are wired correctly.

Why is my Kicker 08zx650.4 amp turning off in my 98 Deville??

ive been hearing alot of this going on yes you had youre system proffesionaly installed but youre amp is pushing at all its got it must be pushing at 1ohms capacity loud but what you dont realize is that.. do ur home work first some amps say they can handle the power but if you read carefully it would read not stable look up amp on the net before buyin review them first ...but evrything youve got is correct its youre amp it wont burn out but you wont get continous power to ur spkrs ..i recomend installing one amp on each spkr same brand if you prefer in keeping it with a crossover if you dont have one that way they wont over heat and cutt off and you will use less power and get more bass...

What makes a nitro 1200 watt amp go to protect mode

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. D .A thumbs up would be greatly appreciated if this answer is helpful to you. makes-nitro-1200-watt-amp-go-protect-lv2kkrmxrai4iihdvw4m3np2-2-0.jpg

Amp getting really hot

Disconnect the speaker wires and the RCA jacks from the amp.

If it still gets hot, the amp needs to be repaired.

If it doesn't get hot, check the impedance of the speakers and make sure they're wired properly.

If they are wired for the proper impedance, check each voice coil with an ohm meter to make sure none of the voice coils are shorted.

If the amp gets hot or goes into protection with no input signal and no speakers/wires connected to the speaker terminals, the amp likely has shorted output transistors. It's not a complex amp. Any reputable shop should be able to repair it.

Amp keeps overheating

Try to turn down the volume??? LOL No really most likly the voice coil is overheating on the speaker, or the unit is over heating. Try to add a fan on top of the unit as I found this on high powered units, that they are being push hard and getting hot. Is the amp really hot when it does this? If it is then its a normal thing as not enough venilation. if its not hot then theres a problem in the amp and should be bench checked by a pro with load resistors and a tone generatoe as well as a scope to check if theres a clipping problem in the output stage.
