I have the BMW Business Loud Speaker system fitted to my 2011 build 1 coupe which has the following:
4 mid-range speakers (2 in the front doors & 2 on the rear parcel shelf) 4 x 25W output.
2 tweeters in the front doors, 2 x 25W output.
2 woofers under the front seats, 2 x 40W output.
Analogue Amp 180W.
can you tell me what parts I need to fit tweeters to the rears?
