    thanks for the reply... you said unless it is 'Bose' My front speakers say Bose on them, so does that mean that the amp is also Bose? If so, do I still try unplugging the rear speakers? (are they the ones in the door?- if so it looks like I will also have to remove the door panel to be able to remove the speakers.) Thanks again

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.

Hope helps.

    I mentioned BOSE, for the quality of their products, however, I want you to do everything suggested and if any brand.

I have a 2004 GMC Yukon XL and the rear passenger tail light and brake light do not work. I checked all fuses and replaced the bulb and it still doesn't work. Theres also a loud and annoying clicking sound...

check VEH STOP fuse in the instrument panel fuse box. If good, check for battery voltage in the bulb connector on the light blue wire with lights on. If no voltage, check for voltage in the rear junction box. Pull connector 4 and check for voltage on the terminal that connects to the light blue wire. If not voltage, you'll have to check the harness between the rear junction block and the underhood fuse block
