sup guys...i have a pair of armageddon 18's. i want to build a ported box for them. its going to be in a 99 jeep cherokee sport. i plan to have 2000-3000 watts each for them. not sure what amps but in that power range though. i want to hit them crazy lows. any ideas on size of the box internally (cu. ft.) and port length? i want to build a slotted port box for them. 3 in pic one more at a friends, but im only gonna use 2. wish i could use all 4 though. thanks
