for 2 kicker cvr 8" subs. the box will go in a 1999 ford expedition behind the third row of seats, i would like it to be vented, needs 1.2+ ports displacment per sub after sub displacement. subs net displacement is 41.1in^3. i will be building the box but have never designed a ported box so will be very thankful for any help. depth has to be about 7 in order to fit back there max length is 49 max height about 15. thanks in advance.

Build a box to the max dimensions, with the port facing up thats 5.5" x 3.5" (it goes back across the whole top of the box since the box is only 7" deep. Give it 25" of length and you should be set.

That will give 1.75 cubes @ 34hz.
