Wow. Looks great.

That's similar to what I had in mind myself, but without any real measuring I had figured I'd only get 2 10" in there. I also wanted to add 2 6x9" above, though, and it looks like you even have space for those.

I figure the top of the door should be high enough to get some decent midrange from the rear, and still not use up any cargo space.

How's the door handling the vibration?
