That would depend on the tuning frequency. Ports are MUCH more then just a hole in a box.....

What 12's are they?

Speaker Port Calculator

Your gonna want to divide that box into 3 seperate chambers. At that point get your exact volume and plug in the numbers to the calculator for one sub and chamber.
