I just installed my head unit from an 03 suburban with bose system to an 05 GMC yukon. Same wiring bundles all I had to do was plug in but now the speakers are very quiet and on top of that the front speakers keep cutting out. They don't lose all sound but it almost sounds like the back speakers only work then they come back almost like a wiring problem but I redid all the wires to make sure that wasn't it. Any solutions? Its a pioneer head unit with the Bose stock speakers.
