Rear Speakers

[Blitzburrgh]

2005 Trailblazer LT. AM/FM/CD.

I lost sound to both rear speakers only. I attempted to pull out the radio but was unable to completely remove the trim (couldn't pull it up over the steering column). I could move that trim peice out enough and unbolt the radio to feel the connections on the back and everything seemed fine.

I called my local Chevy dealer and they said there is a single 'lead' wire that powers the rear speakers. She wouldn't get into specifics with me when I asked where it ran and what color the wire is.

Anyone know what color wire I'm looking for and where it runs? I assume it's broke somewhere.

Everything else works fine on the radio, just no rear sound.
