Rear Speakers to Components - 4 Door


Current set up: 2013 C63 with Harmon Kardon Logic 7
Proposed set up: Audison BITDMI, BIT 10 DSP, Run a 4 channel amplifier & mono amplifier. Intention is to run front and rear components in the doors.
My question is: Has any body run component speakers in the rear doors?
What kind of speaker depths can the current hold, How much more effort is it removing the speakers cleanly without cutting and using the stock baskets? Where can a cross over and tweeter be mounted. My intention was to mount the tweeter to the dummy tweeter covers (Use a clean wide holesaw and flush mount a tweeter here. It looks absolutely tiny and i will need to source a set of rear components with a small tweeter.
Has anyone attempted this?
