My B5 has bose symphynie sound, but now one of the rear speaker start making rattling noise while playing song that has low base. I was thinking fixing it but taking it to the dealer might be more expensive then getting new speakers. I am not that good with electrinic so I decide not to fix it myself. What do you think is the best couse of action? If it were to get new one, any suggession on some good one? any better then bose? I did the search on this forum but can not get a clear answer on this, thanks for your input. This forum has help me many time with my Audi, thanks for keeping it up.
