I know I'm also late to the party. Here is my experience with my '07 Outlook XR (non-Bose? at least I don't see "Bose" anywhere). The headlight and door beepers were usually very quiet but occasionally full volume. I determined the sound was ONLY coming from the tweeter on the door pillar. My radio sound was quiet and poor sound! By adjusting balance and fader, I determined the front door and passenger rear door speakers were not working on a regular basis. I pulled the drivers' door panel and I could see the speaker cone was severely damaged. I connected a spare speaker which worked fine. I also had water in the wiring plugs but dumping the water did not seem to help any of my problems. So, I replaced all four door speakers for about $90 from Crutchfield and I now have door beepers and good stereo sound!
