The boxes ugh man I forget what the measurements were(i'll get them later). They're basically each 1.63 cubic ft that can slide almost all the way in there and fit REALLY snug *but still fit. The amps have a piece of plywood screwed into the metal behind the carpetting(what I couldn't screw, I'd glue) and the amps are screwed on top of the carpet. I just ran the wires underneath the carpet and voila.
