Ok im currently running a xx-colossus II but im trying to get my ma audio hk4000d to work, but if that fails, im going to get a different amp, and i was wondering if the hifonics xx-cyclopse (4000wrms) and xx-goliath(5000wrms) would be ok to run at .5 ohms daliy. So let me know if they would work, im just going to want the more power because the subs want it as so do I.
