front doors are the "MidRange-BW-635 model", 4.5 inch size
if you are looking to a cheap solution I suggest you to put in
1) at least the fronts and the tweeters
2) then you could change the subs below the seats
putting in an amp is not so easy & plug & play on BMW, I do not have one and I am satisfied with my setup described on post #2.
I do not suggest to work on the back speakers, but if you like to change them, they are size 4" (so a bit smaller than the fronts)
about the wiring of the tweeters , basically you can connect the tweeters to the mids directly (the mids have an "in" port" where you connect the wiring from the car, and an "out" port where you connect the tweeters. in order to put in place the tweeters you need the trims, for F20 are the ones below
Left Door Trim with Tweeter slot
51 33 2 240 351
Right Door Trim with Tweeter slot
51 33 2 240 350
