I just recently bought 2 Kicker Comp CVR 10s and an Hifonics Nemesis NX600. Right now I have the Kickers in a sealed Audiobahn box w/ about 1.5 cu ft each, but they're just sitting in there because I plan to ditch that box anyways. Before I go and waste my time building a ported box I'd like to know if the Tempest would be much better SPL wise? I would be able to run my amp at 600w bridged @ 4 ohm so I think that would be plenty of power for it. I listen to mainly rap so I was thinking that I would most likely make my own ported box for the Tempest. Aside from that, I'd love to show all the RF and Audiobahn using dumba**es at my school up w/ a brand they've never heard of. Any advice?
