i am installing two GNX104's in a sealed enclosure with two chambers of .74 cubic feet. This is the most volume i can acheive in my installation (91 Ranger reg. cab). how will these subs perform in this enclosure? is this close to what they need, or am I kinda choking them off? I like my bass kinda tight, but with some low end to it, as i listen to rock and also some rap. Pushin' about 250x2 peak from my amp with the amp crossover @ 80 hz.
