his car=48wide 21 high 26.5 deep

4.66662 cf. first chamber ported at 20.0954 hz with 4 two inch id pvc ports 16.5 inches deep .15 port volocity at 800 rms
2.33331 cf. second chamber ported at 28.419 hz with 4 two inch id pvc ports 16.5 inches deep .11 port volocity at 800 rms
space taken up per port .046142578125 cf. (.1845703125 cf. for each front chamber) ( .0928515625 cf. for each interior chamber with the ports evenly spaced between the two chambers)
.5537109375 cf. space needed in box size over the 7.00 cf target to account for all port displacements
.277421875 is cf taken up in chamber 1 and 2
4.944041875 gross chamber 1
2.610731875 gross chamber 2

24.00 wide by 15.5 high by 23 deep=4.9513888 cf this is the demensions of chamber 1 internal you must also add a .75 mdf wall dividing chamber 1 and 2 (so account for that) and place each 2 inch port one over the other height wise evenly spaced length wise between the two chambers this is for the interior ports
12.6875(11/16) wide by 15.5 high by 23 deep=2.61753110532407 cf

only thing i need is the displacement for the subwoofer and ill add that into chamber 1 and were done
these demensions are internal so add 1.5 inches to length width and height because well be using .75 mdf


if i charted this box by theory right you should hit from to 20 hz to 55 hz after that you prob wont notice much except by cabin gain

youll do four 2 inch ports on the front of each chamber 16.5 inches deep and four 2 inch ports internally as instructed above
