Depending on the size of the speaker in the kick panel, I believe its roughly a 5 inch diameter, bmw uses over sized speakers, meaning they usually use a 5 inch speaker but the hole is cut out for 6 inch driver, they just use a plastic cup around em.... If this is the case they should just drop right in...
PS: I replied to all PM's regarding the speakers fellas.
