I went out and tried it again.. Its only 20 degrees out, snot was dripping out of my nose like crazy.. But got it all hooked up. Little disappointing, not nearly as powerful as the A3000db. unless i change the input sensitivity for 2-8v to the other setting 2000mz or whatever it is. But im sure thats not good for the amp. when i get a wild hair up my *** and feel like bearing the cold im gonna wire it up to 1 ohm and see how bad my volts drop. Its sad that this amp makes as much power @ 1ohm as my old amp did at 4ohms.
