i'd make the box atleast 6 cubic feet internally. the port can be determined by looking in the sub manual it gives the port it requires

If you say "I already know how", don't ask me a single question.

These subs were designed to be run in a sealed box, its hard to get a smooth ported box. For best results for spl, and some sq, go for 3 cubic feet for each sub individually. With that size of box, be shure to use braceing as these subs will break stuff if you feed them more than the wimpy rms rateing alpine gave them.
