then type kicker lol

kicker specs are general specs tho. and anyone that uses kicker knows to add 25-50% to the box specs and tune lower than they call for to make em get louder and sound better.
i promise you if you put 1 in .88 cf sealed it will sound like pure asssss

For L7s, go HUGEEEEE on the box. Id personally go for about 3.5 cubes per 12 ported.

yeah i was saying 10-12 as a minimum. they sound horrible in small boxes.
gotta remember a square sub 12" is pretty much a 15" round on cone area so build accordingly :)
