What are you looking for spec wise; size and tuning? I am not a designer but it would help to know.

ya 40 wide 23 deep
and ya im thinkin 33hz seems to be what would work for a kid that listens to manly rap and bass music what do you think ?

33hz is usually a good place to start if you listen to rap. I just finished the design for it I'll PM you in a second

Well before I go and send you all the info how does this look? Max dimensions are what you listed, ~1.8 cubes per sub, with a 32-33hz tuning

Alright cool stuff..lemme just get the measurements real quick like and ill send this on over to you. Stuff like rounded corners and those 45o angles aren't required but if you have a router with a roundover bit or a table saw that can cut 45's it will improve the overall performance of it a tiny bit.

EDIT: alright I'll move em to the front. Though in a van or any kind of SUV sub up port forward is usually loudest

sorry this box will be under a seat and the only way for the port or subs to face would be forward
