I decided i am going to build a box myself instead of buying a prefab. I own a 2001 Mitsubishi eclipse gt and the hatch is pretty small. First off i need a box design or is there a box building program i can use. the only one i know of is the RE box calculator.
My dimensions are 30in side to side, 16in depth, 15to16inch height(16 is pushing it), those measurements aren't max but something that would fit inside my hatch.
The sub that is going in there is a AB xfl1522 running off a PPI BK 1300. I heard that the xfl's like to get low so i want the box to be tuned pretty low like 28-30hz. if anyone else has a suggestion for tuning let me know.
