Question about Pioneer GM-7200M Car Audio Amplifier

1 Answer

Pioneer GM-7200M 800 Watt Amp shut off and wont turn back on.....

I am stumped.
My amp (listed above) has worked wonders for me for almost 2 years. Out of no where it shuts off (while i was driving) and will not turn back on no matter what i do.
I have tested the power cord and it is running power.
Ground is grounded, trigger cord is connected right.
The two 30 fuses are not blown.
And yet the amp will not power on.

I need to know if there are any other things i can try to fix this problem.
Like maybe an on board fuse that i need to replace (which i doubt because the outside ones are not blown)
Maybe something got knocked loose (even though it is secured in the car)
If anyone has any good ideas please let me know.

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

Amps on woofers are fine just won't hit


your probably making your amp run to low ohms if its a 2 channel amp bridged to one channel you can probably only run it at four ohms

Also seeing as your subs are 2ohm dvc you can't wire them individually to 2ohm and use each channel separately. So i'd recommend buying a 2ohm stable monoblock or running it at four ohms. a 1400 watt amp'll still pound at 4ohms and it'll extend your amp's life span

Pioneer GM-7200M 800 Watts Mono Amplifier


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

It should be better to use the Pioneer GM-7200M Amp with your subs.

For 8 ohm setup hook up this way:
Amp out+ to Sub1 +
Sub1 - to Sub 2 +
Amp out - to Sub2 -

For 2 ohm setup hook up this way:
Amp + to Sub1 +
Sub1 + to Sub2 +
Amp - to Sub1 -
Sub1 - to Sub2 -

Is it good


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.

Pioneer GM-7300M 800 Watt amp will not power on


This may have a different type of triggered turn on wire. On some of the older Pioneer amps (and maybe some new ones) the trigger wire would SUPPLY B+ TO THE RADIO and when the radio was switched on the amp would sense a current draw on that wire and would then switch on. Unlike most common amps which sense the presence of B+ on the trigger wire supplied by the radio and then turn on. Look in your owners manual to see kind of turn on system you have. If you don't have an owners manual then perhaps you can download one from Pioneer support. good luck
