I need circuit board schematics for pioneer GM-7200M car audio amp

SOURCE: Amp is on, Subwoofer works, but no sound.

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

Check your GROUND wire might be touching something and making bad contact.

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

Hiya, first check by triggering or powering the amp manually by putting a voltage at the trigger. Just use a jumper from power. If the amp comes on then check the feed from head unit. Loose wire, inline fuse near the head etc.

If it still doesn't come on the hate to say its gonna have to go in for repair. Could be anything inside from protection, blown track etc.

Hope that helps
