I have a 1989 vette with the Bose system with a seperate amp for each speaker.I replaced the rear speakers with 6X9 speakers and now have no sound to the rear
I removed the rear amps and connected the left side yellow Pos and brown Neg wires to the speaker and the right dark blue Pos and light blue neg wires to the speaker but still not sound. I did replace the orginal Bose radio with a Pioneer CD stereo and was told this was all I had to do to make the stereo sound great. My frond door speakers still have the original speakers & amps and they work
