What 2 get

its a 31" long x 15" deep x 15" tall ported box. powered by a 1200 watt mono hifonics brutus amp. its loud and sounds good. i just want extrememly loud for not goin broke.

ur not going to get much louder than u r now with just one sub in less u spend alot of money on a solo x or something i don't care what someone tells ya!!!! why don't u just buy another L7

there is no such thing as going extremely loud and not going broke. you gunna have to start getting into SPL stuff that isnt cheap.
