hi there i think i need a bit of help. have a 1997 chrysler voyager le with the infinity speaker sysytem. i tried to fit a new cd dvd player with 7in screen but am only getting the front 2 speakers working. works fine if i fit the original stereo back in . got the adapter (part no px720) but still the same. am i wiring something wrong??? please help me i really want to play a cd and hear it properly.

 

U need to do a rewire of 1 wire or make shift a paper clip or something like that in the NBS relay Name Brand Speaker realy.
Or the correct way connector 2 on the back of the radio dark green and red wire needs to have 12 volts on that wire when the radio is on. SO get a jumper wire from a 12 volt source when the radio is on and splice it into the dark green and red wire.
