I've decided to go with a sealed box for my sub, my friend is helping me build it soon. However, I'd like to know some things before we start.

Where can I find a box program?


How do I tune my box to this sub's specs?

And, just for future reference......it appears as though you'll want to stay with a sealed box for that sub; high Qts (.64) and low EBP (40.58)......
