6.5 Infinity Kappas, custom fitted in doors (how well can they fit?)

[Legacy]

I did some searching and figured out most of what I wanted to know. However, I still have a few questions about mounting 6.5" speakers into the doors of my S13.

I'm coming up on an opportunity to get 75% all Infinity/JBL products. I figure at that price, I can't lose. I'm thinking I want to try out the 6.5" 3-way Infinity Kappas for the doors. The question is, how do they fit? It sounds like there are a few people around the forum that use these. Before I order them I just want to know that I can mount them w/o the magnet sticking out too much restricting my windows from rolling down and also that the foam of the speaker wont rub on the door pannel. I wont need to trim anything will I?

Also, I'm gonna leave the 4x6 size in the rear. What speakers would you guys suggest to mate up with the front speakers? Kappas only come in plates in the 4x6 size. Would I be better off using 4x6 JBL ovals in the rear to provide more bass since I wont be running subs?

Thanks in Advance,
Dave.

BTW... I would have asked in an audio forum, but not all those guys drive S13s, and my question needs S13 expertise.
