Depends on what you want to spend. Based on what you described above as your setup, I would look at the MB Quart QSD 216 (6.5") and the MB Quart QSD 213 (5.25"). the only thing you may want to check is the 6.5" fit in the doors. They may be too deep. I would swap the positioning from what you described, and put the 6.5" in the back, and 5.25" in the doors. I assume you are trying to avoid cutting any more into your car than necessary.

If you want to save a little $$, you can look at the PCE 213 and 216. They are good speakers, but significantly less expensive. I don't know how serious an audiophile you are. Some people can't hear the difference. And if you have a targa or a cab, or drive with the sunroof open, you probably won't notice a difference.
