Unfortunately my amp is starting to go bad. A few weeks back I lost my front channels followed shortly by the rear. Two days later the rear channels spontaneously came back, so I’m sure there not long for this world. Two question: One, can anyone confirm that the bose 2003-2006 non-luxury amps are interchangeable between all crew cab 1500 trucks. Two, does anyone know if there is an aftermarket harness that would allow me to use an aftermarket amp with the stock wiring.
