I'm having a hard time choosing between two amps and I need your insight. I'm looking at the cactus amp, CS PF 600.1 and the American bass amp, VFL 500.1 . bothe amps will keep me in the 0-600 watt class with Usaci which is where I want to be. my system will be running right at 14.4 volts. the cactus amp is in sweeden, is $200 less then the American Bass amp but @ 1 ohm is 2901 watts and the American Bass amp is in the US and is 4700 watts at 1 ohm. please help me.
