Question about 2003 GMC Yukon XL
The Amp (unless its Bose) controls only 2 speakers. So i would guess
that atleast one of the speakers controled by the radio is shorted. It
takes only one shorted speaker to shut down all audio. Its a protection
circuit in the Delco system.
Here is what I would do before I would condemn the amp. The rear most speakers are usually the problem. The covers simply pull off. Remove both rear speakers (9/32- inch nut driver) and unplug them. See if the radio comes back on.
If you can hear just one of the speaker, then the amp on that system powers all of the speakers. You have one of the GM High end systems. The amp need to be repaired. Call United Radio at 1-800-448-0944, tell them the part number of the amp and the can tell you the repair cost.
