Question
QUESTION: I my wife has a chrysler voyager year 2001 you may know it has a plymouth it has a factory fit radio & on the back there is a single wire that somehow turns on the speaker amp I am told it is something to do with the PCI bus - I know you're not an expert on aftermarket stuff but do you know if there is anything I can do with this wire to make it power up the amp if i am not using the factory fit radio.

ANSWER: buy a radio harness to replace the radio
you need to power  12 volts in to the blue wire  to turn on the factory infinity amplifiers

good luck

QUESTION: thanks for your reply - I have a radio harness which fits fine but it doesn't cater for the white wire with purple stripe which at present goes into it's own connector on the rear of the factory fit radio. It is this wire which i don't know what to do with I have tested it when the existing radio is on 7 it has no volts on it. i am told it has something to do with the PCI bus i need to do something to fool the car into thinking the factory fit radio is still connected - any clues?

Answer
look at the plug or the other side of the plug
you need to supply 12 volts to the blue and white stripe cable  sometimes is blue only,this will turn on the factory infinity amplifiers
the pci buss of the vehicle have northing to do with the radio
