'01 suburban, no sound from aftermarket headunit.
Okay I was installing subs for a friend that has a 2001 suburban and when we plugged in the wiring harness and all the good stuff, the headunit turned on but no sound was coming from the speakers. I didn't bother running the p.con or anything because we ended up putting in the factory head unit so he could have some music while driving.
So my question to you all, is did we get the wrong wiring harness? He has a 2001 suburban with factory sub and with onstar but NO bose system. Or is there something that I missed?
