Default 4 sa8s port question

Im doing a build soon for someone and its going under the seat of a 02 chevy silverado extended cab.Now my major question for the box is port area,iv been reading on the forum and found someone saying to use a 4" aeroport tuned to 32-36hz. So i did the math on torres and I can get 2.25 cubes with the subs and a single 4" aeroport tuned to 32.08hz with it being 11 3/4" long. Would i need to worry about port noise? Thanks for any reply on this.

I'd do a single 4" aero per pair of subs, one port on each side facing the rear doors, adjust length accordingly to get the tuning desired.

Box turned out awesome. Went with the 4" aero and tuned it to 35hz, and i also resined the entire box. Slammed harder than 2 10s he had before.
