2001 Yukon Premium Sound System

[willy&bella]

We are looking for information and perhaps a wiring diagram for the sound system in the 2001 Yukon. Specifically looking for information on the amplifier. Can it be easily changed for an aftermarket unit? If so, which units and how much trouble is it going to give us? Second, where is the sucker found and how will we know we hit pay dirt?

Any and all information would be greatly appreciated.

Thanks

Ed

Amp is around the glove box area.
