Hi there,

I'm working on my wife's '05 TrailBlazer. No sound from the speakers, but the radio picks up station info. It has the Bose radio and amp. Fuses are good, and speakers don't appear to be shorting.

I was using a digital multimeter to check the speakers from the amp harnesses yesterday when I decided to test the drain wire. Each harness has one, but neither of them toned when I checked for continuity with ground. Does that make sense?

I'm not an electronics guy, but from what I've read, at least one end of the drain wire should be grounded. Do they maybe ground through the amp?

Anyway, I'm about to give up on this and take it to a shop. Any suggestions are appreciated.
