Being an old school MB Quart fan, I dropped a set of the German Maestro EFS4008 separates in the doors and it sounds phenomenal. I plan on doing the SWS sub replacements under the seats, and adding an amp. I have a thread showing pics of my install.

For the doors, you need a 4" speaker and the tweeter housing will accept the German Maestro tweeters perfectly. Depth is very shallow in the doors so don't exceed 1.6" or so for speaker depth.
