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

Hope this info helps
please let me know if you need any further info

white is left front
grey is right front
green is left rear
purple is right rear
blue is power antenna(if available)
blue with with stripe is amplifier remote(should have one if there are RCA connectors on the unit)
black is GND(ground)
yes you are correct. the stripes on the speaker cables are the GND

Pioneers are easy: red is iginition, yellow is battery (or memory), black is ground, blue is remote for amp or power antenna, orange (if it has one) is illumination. Speaker wires are white/white blk, grey/grey blk are front speakers...purple purple/blk and green green/blk are the rear speakers...

Wiring Color Code:
Yellow
To terminal always supplied
with power regardless of
ignition switch position
Red
To electric terminal controlled by ignition switch (12 V DC)
ON/OFF
Blue/white
To system control terminal of the power amp
or Auto-antenna relay control terminal (max. 300 mA 12 V DC).
Black (ground)
To vehicle (metal) body
To speakers:
Grey = right front (+)
Grey/black = right front (-)
White = left front (+)
White/black = left front (-)
Violet = right rear (+)
Violet/black = right rear (-)
Green = left rear (+)
Green/black = left rear (-)
RCA connections go to external amp:
Red = right speaker
White = left speaker
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.

Pioneers wiring is easy. Red is ignition-Yellow is battery-Black is ground-Blue is remote for amp or antenna-Orange is illumination-Speaker wires are usually grey, grey w/blk stripe-white, white w/white stripe-green, green w/blk stripe-purple, purple w/blk stripe. Green and purple is rear, white and grey is front

what car is it?

On Pioneer, Green wires are left spkrs, Grey is right spkrs solid is positive black stripe is neg.

the cavalier wiring-top row is orange 12 volts regardless of the key switch position,yellow 12 volts when the key is on/or accessory, pink is for power antenna or factory amp turn on, grey is for lights dimmer control, black ground,green right front speaker +,light green right front speaker -,grey left front speaker +,tan left front speaker-, bottom row is brown left rear speaker +,yellow left rear speaker-,blue right rear speaker+,light blue right rear speaker- be carefull because you have 2 yellow wires and 2 grey wires if you follow the rows like I explaned you will be fine-If you need the wiring for the pioneer radio E-Mail me at [email protected]

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.
