Soundqubed hdc3 12

I'm building a box for a Freind, it's for an hdc3 12. He will be running a kicker zx2500.1 at 2ohm so 2500rms. How many cubic ft should the sub see after displacement I was thinking around 2.25 cubic ft with around 15sq inches of port per cube at 32hz?

Sounds good, maybe a little more port, say 16 or 17 per cuft of volume.
