box specs, 2 kicker l7's

its time to get the stereo into the new car! build is for a Scion xD. 2 12" Kicker L7's ZX 1500.1 (kicker ss65.2 off zx450.2 for the doors run off an avic-f90) the space i have for the box is 38.5" wide 33" tall 13" deep i want teh subs and ports to be facing into the cab towards the top of the box (so they clear the rear seats) the top of the rear seats sits at 21" high. dual or single chamber doesnt matter port tuned to low 30's i dont HAVE to use all the space for the box, but i would prefer it be as big as possible so i have less wasted space. if the box is smaller then i still want everything to stay the same, only change the height, and i need help figuring out a way to "prop" up the box so it stays closer to the roof and i can have storage under the box.

A box that is dual-chambered will work fine. Box: outside dimensions 38.5"wide x 24"tall x 13"deep made out of .75 MDF. The chamber is divided internally. Two ports will be needed, one per chamber. Ports: Each port is 2.25"wide x 13.25"long x 24"deep to give a tuning of about 34hz This should give you a full and powerful boom. Ganbatte ne!Never send your ducks to eagle school.

The difference between ordinary and extraordinary is that little extra.
