since it is a single subwoofer and dual voice coil, u can wire ur 4 ohm load on any amp u want that does 1000 watts on 2 ohms. for example, i have a 600 w att 4 ohm rockford t1, and my amp is a 600 watts a 2 ohms,
look for companies like kicker amps, mtx, rockford, jl audio, alpine,
if ur on a budget go for hifonics. they are cheap but still sound good.
