Question about Car Audio & Video

2 Answers

Pioneer Amp Hey i saw your answer about an old GM-120 pioneer amp. I also have the green/black wires and the grey/black wires for speakers. The green/black set works good on whatever speaker i hook up to it but the grey/black one always makes whatever speaker is hooked up very quiet; almost inaudible. Do you know why it would be lacking power; could it be a resistor problem in the amp? Thanks

It could be as simple as a resistor but that's not likely. To find the problem, you'd have to follow the signal through the amplifier.

Are you sure that you don't have a bad connection in one of the cables or the connectors that go between the head unit/EQ/DAB and the amplifier?

Grey = right front (+)
Grey/black = right front (-)
White = left front (+)
White/black = left front (-)

RCA connections go to external amp:

This is the basic layout for most all stereos. The ones that have an orange or orange/white, this is the illumination wire.
Good luck.

Old pioneer GM120 amp


ok first the large red is battery connection, black large is ground find good source to ground, the 0.75 is most likely the power on for the amp you should hook it up to the power antenna wire on the radio. this will turn on the amp when the radio is turned on. the grey green and black are prob speaker hook ups input. the four wires are speaker outs, the red wire might be power for cd changer test it to see if it puts out power when amp is on.
