Hello I have a 07 Chevy Trailblazer with the Bose stereo I recently bought a double din head unit and the pac wire harness LCGM24 (if it helps) I installed everything and when I plugged the remote wire from the harness to the radio I get a loud static sound. I haven’t installed any amplifiers yet. I ran a ground from the radio to the chassis and still the same problem. I then installed a power noise filter and same problem. I’ve tried everything that comes to mind but I’m at a loss. If anyone has any answers for me it would be greatly appreciated.
