any out there change their speakers on their 2001 BMW 330Ci? i've heard so many different takes on this. first of all, i can't find anyone who can tell me what size speakers are in front and what size are in the rear...plus i can only find 8 of the 10 speakers. 3 dealers i talked with don't know anything about the speakers and can't tell me where the other 2 are. i went to a couple shops and one says i shouldnt' change them at all because the stock speakers are so good (not the HK system). the other place would do it..they would use 5.25 components in front and back..which still doesn't explain where the last 2 speakers are...personally i think the stereo sounds good, but i've heard better..which is why i want to change..
