06 Trailblazer LS - had the most basic single-disc headunit (no Bose, no amp) and in the past couple of years we've noticed that the sound started crapping out and eventually would only come out of the right front speaker. It'd cut in and out periodically, too - and the sound got so bad over time that it'd simply be a very tinny, weak sound out of that right front speaker.
The TB wasn't getting driven much, so we didn't worry about it - but now my eldest is turning 16 and she needs a car. And, well, she'd like some music.
Replaced the head unit with a cheap single-DIN using the Metra harness, and we got little improvement. We did start to hear sound out of the left front, occasionally - but again it'd continue to cut out and we'd have no sound for a while. So I bought some cheap Kenwood 6.5" speakers for the front doors, and replaced those - used the pigtails supplied with the speakers and crimped them with butt terminals into the red and black wires I'd snipped off the old factory speakers. Still nothing.
Other than a short somewhere between the head unit and the speakers, I'm at a loss.
Any suggestions on a troubleshooting path from here?
