what kind of amp are you running for your subs , if i was you i would build this
1.75 ft3 (49.6L) + port displacement
2.5 x 12.5” (6.4x31.8cm) port, 20” (50.8cm) long
2.25 ft3 (63.7L) + port displacement
3 x 12.5” (7.6x31.8cm) port, 20.5” (52.1cm) long
do this times 3 times with divided walls
or just build a box that would fit all 3 of them side by side say 36 wide x 25 x the 15 and use the aero ports im selling then you will have good spl
hope that helps aight !!
