hmm.... 8's in the doors. I've already put MB Quart Premium Ref component coax's in the doors. And I don't think I can build a box that'll fit in the doors...

Crutchfield says that I have 6"s of mounting depth in the rear speaker location. I figure an 8" sub has about 4-4.5 inches of mounting depth... therefore, I can just barely fit a box in there.

I still have to take the panels off.... see what I'm dealing with here.
