Ive had my subs for about 6 months, but because Ive been concentrating on performance upgrades they've only had about 1 months use They're rated at 200W RMS, Single Voice Coil 4ohm That fusion amp you're looking at will only deliver 125w to those 2 fusion subs at 12.6v Because they're Dual Voice Coil subs they'll have to be wired in parallel, drawing on a 4ohm load, and that Fusion amp only delivers 250w at 4ohm @ 12.6v. As mine are SVC, with that amp they'll draw a 2ohm load giving the subs they're rate 200W each
