I have 4 L7s Dual 2ohm subs. I was going to go with 2 1500x1 kicker amps, but it looks cheaper to go with other amps that i have usud in the past, but i havent been into stereos in a few years and was wondering if the orion HCCA 5000x1 or two soundstream 2000x1 would be my better choice. Does anyone know anything about these amps?
