Hey I just got a L7 12 and a 1500/1 Kicker amp. I've been trying to find answer's on the enclosure i should use and i've determined ported 2.5 cubic feet will do the trick. unsure though of how big my port needs to be? I've read 28-30 hz's is what i should run it at and i'm assuming that plays into what size the port needs to be. If theres anyone out there with suggestions please reply.
