I have a 2008 cadillac DTS. No sound coming from the radio. Replaced the amp as i have read here on the forum. All visual functions on the radio work. Even from the steering wheel. Lost and confused.
I've even searched everywhere for a wiring diagram for the amp. Can find radio wiring diagram everywhere. It has the Delphi AMP not the Bose system.
Sorry to bother everyone. Just found the problem with the pink trigger wire. The plug end for the back part of the rear seat was laying on top of the harness going back to the AMP. It had cut into the AMP wiring harness clipping the pink trigger wire. Houston we have sound and chimes.
Thanks again for this forum.
