Need box formula

[irishboom]

Can someone send me the cubic space formula for building boxes. I own two rf 12 inch HX2 DVC 4ohm subs. My amp is a punch 800.2. each one will be getting about 400 watts RMS. the range of sealed space for an enclosure is 1.75-4.0.It's getting installed into a 2001 cavalier with a descent size trunk.
