Hey guys, Not sure what the best option would go for sub/subs, would prefer 1 sub if i can get away with it, Amp Is 600RMS @ 4ohm 1000RMS @2ohm, i was thinking of running a 2ohm l7 @ 1000RMS 15" off it, any better ideas?

i would get a 15" fusion powerplant and run it at 4ohms, i have that sub and it sound awsume..66L ported box with a 350mm long and 110mm wide port is ideal for it.
