Amp cutting out

My amp cutts out for a second or two after about 15 minutes. Originally i thought i wired my amp and subs wrong but this is not the case. The amp does get warm. I have my gains turned almost all the way up and I dont have a farad cap. Could one of those cause this?

Sounds like your amp is over heating. it wouldnt have nothing to do with a power cap as it would just die. your making your amp work to much. look into bying a line driver as this will boost the volume going into the amp wich will also make the subs louder

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...

Amp or something cutting out.


Power caps store power from the battery and they feed constant power to the amp so you dont get no drainage! this could be one reason..

have you bridged both subs and wat gauge wire are you using.

these amps can only handle one bridged sub at 4ohms and this amp is recommended that u use 8gauge or higher. if your running to subs i normally reccomend using 4 gauge power wire as you get more rms power feed to the amp

you can get a power cap or anyother accersory cheap online at my suppliers.. caraudiosecurity << click to enter >> hope this helps and please rate me :)

Amp or Stereo Cutting out...


I agree with what you think it might be. I really think its the deck that is bad and you should be able to take it back for a new one. Have you tried unplugging the RCA cables to the amp to see if that stops it? That would tell you if the amp is backfeeding or doing something weird.

Amp staying on but cutting out?


Hello Willb2396,

Actually you answered your own question in your paragraph. I draw your attention to your statement of:
"It will work for as long as I'm driving I will park my car, and when I turn it back on every thing will be working just fine and, then a couple minutes later, amp cuts out and won't hit for a couple hours or a couple days.... I have checked the sub multiple times and I don't see it being the sub or the amp"

You are correct it is neither the Sub nor the Amp. The problem is either your voltage regulator or your alternator. one and or the other is going bad.

Here is some advice check your ground wires, the buy a dual alternator kit, it contains the parts you will need to add an additional alternator to your car. This will provide the power you need.

I hope this helps,

Thank you,

Music not playing from subs


Do this for the sub amp...

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

AMP FOR SUB SHUTS OFF SOMETIMES


your amp may be overheating, or you have it up too loud and the surge protector is shutting it of in fear of damage to your amp.

Protection Circuit


Yes, always a good idea to use a wire wheel and drill to get a super clean place for your ground. That was going to be the first thing I suggest. I would use a meter and see how many ohms the subs are at right now. It may be two low and there is too much current demanded form the amp at once. for a good sub wiring guide, go to

Amp not powering up??


the sub amp may be damage, shorted. you may have a wrong speaker hook-up the first time you use it. too low impedance may have damage the sub.
