yeah i don't recommend going with hifonics, the bx1000 is a 700rms bridged at 2ohms and its not a real big namebrand that would work well with those 2 awesome subs totaling 1000watts rms of the best bass out there (rockford). if you wanna go with hifonics, go with the bx1500, but i recommend going with the rockford 1001bd amp, i have it for my 1000watt rms power hx2 sub and it works so awesome. i got it on ebay for $300 and i don't regret it at all. goodluck.
