i want to try to get 4 12's kicker cvxs fit in the space i have 2 of the subs will be facing the roof the 3rd sub will be on the right side of the box and the 4th subs will be on the left side of the box

i would like to have the box ported but if not enough airspace then sealed would work as well but how much difference would the loudness be

the dimensions i have to work with is 27 long 17.5 wide 30 deep

and if thats not enough airspace i can extend the length to 34 but it has to become smaller

those dimensions will give you about 8 cuft and the recommended vent box volume is 1.75-2.25

if you take into consideration the displacement of the subs and port(s) you may want it to be a little bit bigger
