5ft^3 after displacement is all you need.

Each sub will probably displace around .2ft^3 each, and shoot for around 12-16in^2 of port per ft^3.

12-16in of port space. is it like tuning? where the lower i go 12 per foot, it would sound different then if i went with 16 per ft?

More port = louder, to a point. Staying in the 12-16in^2 of port per ft^3 is pretty much the safe zone where you won't have to worry about any adverse affects of too small or too big of port.
