I am new to this website. I have a 2007 chevy trailblazer LS with bose. I cannot find a stereo wiring diagram that matches what's in my vehicle. I am trying to install an aftermarket stereo. Any help will be appreciated. I have been thinking about just running new speaker wires directly from the door speaker to the fton of the car, and not worry about using the stock wiring harness for the speakers. would that be a good idea?
