I have a 800W pioneer amp, model GM-7200M, along with a new 12 inch pioneer subwoofer. I installed them both two days ago and they are brand new. It sounded great and everything worked. Then just recently the subwoofer didn't sound anymore. The subwoofer is ok and the amp light turns on. I don't understand what could have happened. I didn't disconnect it at all since it was installed. I checked to make sure everything was connected, but still no sound from the subwoofer only my speakers that aren't connected to my amp work.
Here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem

I have used Pioneer before but have not run
across this before.sounds like you may have
drove it a little to hard, and and zap one of your amps inside.Take the top off and look
around and smell.
Maybe This Will Help
you Amp is overloading and going into protection mode. if it cuts out with the wire u were using first then their would be no need to upgrade the size of ur wire cause that would only be, doubling or trippling the power u are getting threw those wire now. bottom line the 2 subs u are using are obviously to much for the amp.
try dropping the OHM's by connection the subs together and runnig just a single positive and negative to the amp! or just get a better amp
If you are using a GM-7200 amp, it should sound great. Both the amp and the subs are rated at 800 watts so be careful not to overload the bass by turning them on full power. It is good practice to have a slightly lower watt amp than the subwoofers. If you can power your rear speakers from the amp, that would take away some power to prevent the subs from overloading. Overall, you should get a nice THUMP!!
u should connect at least six 12" subwoofers (preferably 1000W each) to that pioneer amp of yours. Crank it up and enjoy. Your amp shouldn't cut off now. If it does cut off, you should change the fuse on your amp to a higher ampere.
Run one set of RCA lines from
head unit to amps if you only have one set of pre-outs on the head
unit, then at the amps, use an electronic crossover to split between
the two amps, and this will also allow you to control what frequencies
go to which amps/speakers. You should use one amp for the speakers and the higher power amp for the subwoofer. You should not try to connect both to the subwoofer. Use 4gauge cables if possible. If you have more questions, just ask.
