No idea how, I don't even have a amp and don't play the stereo loud but for the last couple of weeks I've had a rattle from the drivers door. I did the normal hunting for loose parts, cables and other bits that can cause the rattle but no luck. I can't even stop the rattle by putting pressure on the door card. Had the door open yesterday with the tunes on and noticed its the speaker it self. I think I've popped it. Any one got another one from a braker? I did think about upgrading but I can't be assed with the hassle of converters and ill fitting speakers. Plug, play and walk away. How much better are the bose speakers over the standard speakers, do they just bolt in with out needing the amp?
