Uploaded with ImageShack.us by the way i am only a highschool kid i currently have a box in my car that has a port way too small and it chuffs like a mofo...till i found out that u had to have a certain sq in. per sq ft.

Also i got dimensions just too lazy to do it on paint i tuned it with torrest calculator and its sitting at 35hz with 13.5 inches per sq. ft.

what do you mean make it 2 inches longer like extend the port to the outside like this? Uploaded with ImageShack.us

Ok, so i am building a box for my level 4 dc 15" box is 4.11 and after speaker displacement and port displacement is 3.15ft^3 so I was wondering if doing what i did at the end...making the port opening 2 inches bigger would make my box higher tuned originally the pot is 3 inches wide Uploaded with ImageShack.us
