2003 Suburban Bose radio no sound

I am trying to troubleshoot my daughter's 2003 Suburban Bose sound system and need schematic or suggestions where to look. Radio seems to be working as indicated by display and headphone on rear console is operational. No speaker sound. Does amp have self protection if a speaker is open or shorted? Is the amp turn-on signal something that can be verified with voltmeter? Amp fuse is good.

Did you find a wiring diagram for the Bose system? I would love to have a copy.

Closest thing was on modifielife.com but it was somewhat generic and did not go in to amplifier specifics as I had hoped.
