You'll need around 4cuft per sub, that's a 16cuft NET enclosure.  Add to that the port and it's length plus woofer displacements and you'll need about a minimum of 22cuft of space for the enclosure.

 

That's a huge enclosure, are you sure you have room for it?  Are you planning on doing a wall?

Alright then, you should have the space.

 

The subs are good in enclosures of 3cuft to 6cuft per sub, however the keep in mind that if you're planning on running more than rated power to the subs you should probably look at the smaller end of the scale.  That's why I suggested about 4cuft per sub and nice easy number to calculate with.  Also, the roughly 22cuft. GROSS figure was only the sub and port displacements along with the 16cuft. NET enclosure size.  That's not accounting for any bracing and you'll definitely want/need that in the enclosure without any doubt.
