thats what i plan on doing. i took the rear speakers out as to put a piece of mdf to seal that passage up. then the rest of the deck lid is gonna get filled with a little bit of expanding foam to get rid of any rattles and seal it up a bit better. as well as the enclosure itself will seal off the 60/40 folding part of the seat and its entry to the trunk. so basically yeah it will be totally sealed off from the trunk.

but i dont think i would be able to get enough out of a box in my trunk to house 2 15's. so either a wall or a rear seat enclosure is kinda my only option hahaha. ive kinda looked and 10-12 cubic feet external is kinda my whole trunk so...
