Are you gonna seal or port the enclosure? Usually I make the enclosure as big as the wheel well allows it, then afterwards Ill use either the water or packing penut method to determine the total airspace in the box. Then I just use blocks of wood to take up airspace inside the box to get it down to the right size. As for total size, just check JL's site and it will tell you the recomended airspace.

it going to be sealed, and last question for now, do i add water after i finish the entire box or just for the wheel well?
