I can tell you my Infinity 6.5s definitely did not fit in the door. I re-read the thread though and it sounds like Spinalguy got 6.5s in his doors? Possibly with a custom spacer?

I haven't done my rears yet. I'm going with 6.5s there for sure, even if 6x9s fit, since I have them and a plate will be easy to build.

Where are you putting your amp?
