it is a general rule of thumb to have around 12-16 inches of port area per cubic ft

you can go less with using areo ports - but not that much less

to figure port area on aero ports you use:

pi multiplied by radius sqaured

2.25*3.14 = 7.065 per port
7.065*2 = 14.13 TOTAL

You need bigger ports - and more of them. what tuning frequency are you trying to go with?
