I have a Pioneer DEH-P8200R , with a MTX Thunder102 Amp, and a MTX 12 inch sub thats not ported. That I am getting ready to install in my 07 chev Trailblazer with a Bose system without Nav, but also has Onstar. (That I dont use). I would like to install this system but dont want to ruin my onstar in case we ever sell the vechicle. I went to best buy to price the harness and they told me it was $150..WOW...would like to get it off Ebay if possiable to get it cheaper but dont know what Im looking for....Any help would be appreciated....Also any and all help with install would be appreciated....where to run the hot wire for Amp ? Where to mount ? questions like that. Any ideas would be helpful..Although Ive done some installs before Im always learning ......
