need help with my box for 4 re sx 12s

[midwestcustoms3 10+ year member]

need to figure out how big of a port i should use on this box. here r the deminsions of the box

w = 36

h = 30

d = 21 this gives me 11.09 cubes, so hopefully after sub displacment and port displacment should bring me down to 10 cubes (guessen)

so i need to know how many sq. in. of port and length i should use and what i should tune this to. this is going in a saturn vue (suv)if that helps ne.

ne help would be appriciated

Ofcourse not! Where's the fun in a small port?//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I like 15-25"sq.in. of port for every cubic ft.
