new box design
 

ok guys iam making a new box this spring when i can get in my shop, stupid snow. anyways i was wondering if someone with box pro or that knows the math behind volume can help me figure out my volume iam going to need. what i want to do though is make the inside of the subbox round, as in now corners. it will be ported for sq. the subs i have are OCTANE-R 12's ill post the specs when i can find them, pg's site isnt working :(. Also if someone could let me know what the recommended resin and thickness should be for the fiberglass.
thx
