My stock radio died, OnStar no Bose. I have the new radio installed and up and running with a GMOS-01. Everything seems to be working well except I have no sound to the rear door speakers. I tested the outputs from the radio to just behind the 24 pin harness with a volt meter and it looks like I have juice going out into the wires. Is there a plug just for the rear speakers that might have become disconnected? I find it difficult to believe that both speakers or a speak wire to each could have failed. Frankly I never used the fade function on the stock radio so I'm not certain the speakers worked when I bought the vehicle. I have yet to take the trim panel off the door and test the wires at the speakers.
Is this a common problem?
Any help would be much appreciated!
