You have a lot to consider!. Is it going to be a sealed or ported enclosure? That will make a huge difference in size. All the information you will need to build a good box should be listed in the paperwork with the subs. Or you can get it from JL's website.

That website really helped me a lot. Another thing i have done was go to the local car stereo place and asked them and they gave me the dimensions and i just build a box off of those. It was like a 200 box on there floor i made it for 35 bucks!
