Welcome!
I always recommend that people use Linearteam's WinISD Pro for all of their subwoofer enclosure designs. For the price (free), this program cannot be beat! Although it might be slightly challenging at first, this program is rather easy to get the hang of once you mess around with it for a while.
If you do not have this program yet, clicking here will begin your download of WinISD Pro.

For all of your other car audio needs, don't forget about the ever-growing Tempe's Car Audio Bible!
