four L5 8" subwoofers in a 08 Ford F-150 reg. cab.

[charlesarms85]

Got a great deal on four L5 8" DVC 2 ohm subs from Bump-n-ugly and need some help with the enclosure. It is going into a 08 f150 reg cab with pocket doors, so i have a little room to play with. I was gonna go vented at the top of the box, but ive decided to go round port.I'm not sure how to calculate the length and stuff of the round port. I'm trying to get 36 hz out of an enlcosure thats approx. 3.5 cu. ft. before displacement. I have the hifonics 1606d and the big three upgraded along with another battery. Any help would be appreciated.

Are you sure you can even get that large of a box behind your seat? 3.5ft^3 ported is going to turn out quite large. Post up your dimensions so somebody can toss around some numbers for you. Also keep in mind that you are going to need some room in front of the subs so they aren't pressed up against your seat. gl man

Dimensions 52w 22h 7.5d with 3/4 mdf comes out to be about 3.5 cu. ft. before disp. if ive calculated correctly.
