Mine was pure custom in my 02.  It was built for 4 12" Memphis M-Class wired for 1 ohm.  The vent was tuned for playing music, not competition. 

All I can suggest is checking out local audio dealers and see what kind of plans they can come up with, and the price.

A good place will work with you on coming up with a plan, and will take the dimesnsions for you and be reasonably priced.  My box cost me $175, but that was a special deal we made. 

Another place in town was going to charge me $300+ and I had to bring in the dimensions. 

I've never gone back to them, and they eventually closed.
