Custom box for a 1999 Chevy Blazer

[bumpinblazer94]

I want to build a custom box for my blazer. I already have 1'' thick MDF i just need some dimensions. i would like the box to fit inbetween the wheel wells of the trunk so it should be roughly 3' wide. The sub is a Power Acoustik 15'' mofo. its wired to 1 ohm. i just dont know how tall the box should be and how deep. i plan on it being shelf port.. Any help would be appreciated greatly! Also how do you determine hz and all that? lol

First find out da specs for da sub as far as maximum airspace. Then Length X Width X Height=? Then divide by 1728 dat will give u ur cubic feet.
