Ive had the car a year, one of its niggles is that the upper speakers in the rear doors don't work. I have spent all afternoon taking out the passenger seat and looking under the carpet for wiring damage - none found and it took me hours. Has anyone else experienced this problem and particularly how I might go about fixing it. Geoff

I'm having the same problems, looks like it's well documented (BM54 failure)
