Does your radio have rear speakers and if so do you have 1 wire or 2 going to each rear speaker?
Yes Joe it's an aftermarket radio.The radio has a diagram for the wires on it ,that said I'm not sure that they are hooked up right.In my car there are only two speakers up on the dash,I disconnected them today ,they were shot.I put two speakers in the back for now.
RickUnless someone made some after market changes to the wiring, the color codes should be:
Yellow - hot when the key is in the on or acc position
