box help!!!

[hockeytoker 10+ year member]

ok so im going to be running 2 HDC3 12's (copper series) on 2 aq2200d amps wired to 1 ohms.

so i want the box to be 35", 16", 20" (W)(H)(D). i think its a lil over 5 cubes.

an obviously i want it ported, but idk how big an all that stuff. idk anything about boxes for subs. so how big should the port be?

im thinkin tunned to 35-38hz. which do u think will sound best?

i listen to rap. an i want some good bass but maintain some sq i guess. more spl though.

so any suggestions help thanks!!

if u were close to me I'd just sell you my box it was for hdc3 12s

anyways, rule of thumb for ports is 14-16sq.in per cu.ft. so for 4 cu.ft (which is what I think u should do, not 5cu.ft. net) you should have 52-64sq.in of port
