Last year, while on vacation, the rear window shattered and glass was everywhere. We don't know how it happened (person trying to break in or freak accident) but we got it home and replaced the window. Lately I've been noticing a buzzing noise from the right rear speaker, which I can assume is glass that has worked its way in there. I have the Bose system which has the speaker covers with holes in it, not mesh. I was looking on internet already and noticed that it seems the only way to remove the cover is take out the whole rear shelf. Is there anyway to remove just the cover? Any help would be appreciated!
