I tried to install a Amp and Subwoofer into my 99 Oldsmobile Bravada, I used the Factory Delco Stereo Head unit, I don't have any other head unit, everything is wired properly and I grounded the amp fine. I did attach the REM cord on the amp to the Switched 12v in the back of the factory Delco stereo, after buttoning everything up I now get no sound from any speakers. All the stereo controls and lights and CD player all work, but no sound. Any suggestions?

the best way to do this is u can call any pontiac delar close to your place and they will give you the code direct by enter some information to your car radio

If you disconnect the stereo, does the temp. display go back to working properly? Did you connect the stereo Illumination wire correctly? Are all the other stereo wires connected correctly? Double check what the wires in the aftermarket harness are supposed to be and don't just go by color.

the make an attachment that converts the size. is your car equipped with steering controls for the radio? the new radio may not be able to be controlled from the steering wheel, thats all

I am not sure about repairing the unit. Do you have a CD cleaner?
You might check with a reputable auto electronics shop, one that specializes in car audio. They may have an adapter that will allow an aftermarket radio to be controlled from the steering wheel. Rosen makes a nice am/fm/cd/dvd navigation unit that also has XM and iPod inputs. The hard part will be to find supporting interfaces and wiring harnesses to fit a 99.
