How to tune my box?

[CentralFC]

Bottom line: I want my box to be between 32-36 hz.

My box is 1.94 cubic feet (20x16x14). The port will be 2.5x14" (35 sq. inches). Now, I'm confused with how this will affect the hz? I want it in that range because I've read that'll provide me with deeper bass. I'm just confused with how big my port will need to be to provide that.

Sub info: Alpine DVC-4 ohm (500 watts RMS at 2 ohm).

Amp: Alpine MRP M500 (500 watts x 1 @ 2 ohm).
