Hey, i got an old amp from a garage sale, the Pioneer GM-H100. I was just wondering if anyone knew anything about this amp because it didnt come with a wire harness or a manual. I made a wire harness out of an old one from a different amp, but i still dont know what the 3 pins go to. I know one of them is for the remote on/off from the back of the radio, but i dont know what either of the other 2 pins is for, or which pin the on/off goes to. Can anyone tell me what each of the pins is for?
Thanks

 

i know this is an old amp, but does anyone know what those three pins go to?

 

Im pretty sure one of the pins is for constant power that would come from the battery, the other is the remote turn-on that would come from the radio, and the other pin is ground to be connected to a bare metal part from your car. Im not sure which order they would be in.

 

but the thing is... there already is a terminal for power and ground. All other amps ive used have a ground terminal, power terminal, and the remote terminal. This amp has both ground and power, but no remote. Instead it has a harness with 3 pins for the remote which is confusing the hell out of me!!

 

a lot of amps have pre-amp outputs which u can hook-up another ampliflier to those pins instead of running a whole new set of wires. im not sure if thats it, but thats what it sounds like. u should jus order a harness for that amp from pioneer. im sure its not expensive at all

 

GMH100 wow long time since I heard that.....

The three pins were for a clip that was teh remote turn on. All my friends use to have these amps and teh clip lock kept breaking so teh remote turn on would come loose and the amp would cut out, and the swearing would insue and you would have to pull over and reconnected the clip.

So in short it use ti house a clip with one wire for the remote turn on.

 

okay, i hooked up the middle pin to the remote, and it wouldnt turn on. I emailed pioneer and finally got sort of an answer. They said that the wire harness is $26 and one wire is for the remote, and the other is for an ACC which i guess is an accessory power line. So what i did was just hook up the middle pin to the remote and the left most pin to the power terminal from the battery. The thing finally turned on and the left channel works great. But the right channel is distorted like crazy so I dont know if i just hooked it up wrong, or if the right channel is just blown. I still have no idea what the third pin is for, if its for anything, but Pioneer doesnt seem to think its for anything, guess 3 pin connectors were cheeper than 2 pin connectors or something... Oh well, what can ya expect out of a $10 amp from a garage sale? Now I can get back to my engine!
