Chino... .43 cubic feet... those 8" shallow mount subs require between .37 and .5
jeepjeepster... not sure about the power seat thing... it does get a little complicated to install however... the sensors for the seat belts are right in the way, and have to be removed from the metal bracket that hangs way down under the seat and tied up higher, as well as the bracket needs to be bent up out of the way... also, on the passenger seat, there is that stupid airbag sensor, that has to be flipped over to the top of the bracket it currently sits on to make sure there is enough room for the sub to play... the easiest method was to take the seats out, and clean up all the wiring, mount the box, which is screwed directly to the floor with 3 2in self tapping screws, and then remount the seat... I made one set that didn't quite match up as well as I wanted to, so I took new measurements using the first mockop, changed the design... and it couldn't have fit any better... I know the pioneer 8" shallow mount sub will fit guaranteed, as this was the sub I designed and built the box around... as for fitting a different subwoofer... no guarantees... unless of course one decides to go with a 6" or such... I have all the dimensions and such lying around somewhere... If I had more tools... I would gladly have built and sold these for those who desired... the only thing is, I don't have a miter saw, a jointer, or a table saw... everything was cut with a circular saw and saber saw... I left the overall height about an inch tall, so I could go around the edge with the circular saw, to make sure everything was perfect, and then sand everything to sit perfectly flush to the top... sealed the inside... and reinforced all outside seams with 2 coats of liquid nail... wish the carpet job was a little better, but nobody every notices... I guess I'm just ****... lol
