Custom TransAm Box Porting Help

[sschoeffler 10+ year member]

Ok I am building a box for my ***** Am and I dont want to lose my T-Top area and the stealth box isnt big enough for porting. So I am building it on top of the hump where the gas tank is. The dimensions are...

Top piece is 14x39

Bottom piece is 17x39

The left and right side pieces are 9 1/2 at the highest and slope down to 8 inches. they are also at an angle (Because of the seat) Had to do this to gain maximum CF. They are also 17 inches wide at the bottom and 14 inches wqide at the top

The two end pieces are 9 1/2x39 and 8x39

So using the rockford fosgate woofer box builder, I come up with a CF of 2.47CF after all my dimensions are added up and put in a box dimension of

15.5x39x8.75

Anyhow, with that much CF will a Fi BL 12 need? It asks for :

Ported box: 1.8-2.5 cuft @ 30-37Hz

Anyway, lemme know, Thanks in advance

Forgot to mention this is going to be a slot ported box. 1 port on each side of the top would be awesome. the top piece is 14x39. I am also putting in just one 12" sub
