If you are not the best at carpentry, what about having the local, reputable, custom car audio shop build enclosures to specifications and you finish them. I would think if you supply the plans and the mdf, the labor would be fairly inexpensive. Maybe $200.00-$300.00 for two fully assembled enclosures. You could get two of the 12" HF drivers, BFD and EP2500 for under $1,000 with the enclosures made by someone else.
