i'd go with L7's. i would get a subsonic filter if you decide to get the 81000d...especially since your going to port the box. If your looking at kicker amps....wait till after ces, kicker is supposed to be coming out with a lot of new **** this year, and all their amps are going to be different, their supposed to be coming out with a big ass amp that will put out max power at 2 ohm's, no one at kicker will say how much it is going to be rated at though. for the money i think the mtx 81000d is a good amp, so is the cadence a7hc???...i know it's the a7..not sure of the last letter. a phd2 (shredder) are also cheap amps that put out 2000wrms. kinda just depends how much money you want to spend, right now i have a kicker zr240 running my mids and an orion hcca 275g4 running my subs and it's one of hte best amps i've ever had, i am switching to all kicker's new amps as soon as their released, which should be within a month or two
