I own the 2002 DHS model with the BOSE system and the person that owned the car before me removed the factory sub woofer. Would it be best to plug the negative and positive wires directly into the dead-ended plugins for the factory sub or should I hook it to a rear door speaker wire? If I have to hook it to the door speaker wires, should I do it right behind the head unit or should I take the door panel off? Also, which wire is the remote wire to my amp? Somebody told me the there is a light pink wire coming out of my deck and is the remote wire to my factory amp but there are two of them.
