I had this amp for a few months now running at 2ohms powering 1 jvc arsenal sub at 1200ws. It was great a 1st even though it says it takes 4 gauge wire and i had to TRIM the wire to make it fit. Then one night it stopped working. no lights, no power. check all my connections and they are all good. The amp just died. its nice for a cheap high Watt amp but don’t expect it to last long. I hope they will cover it under the 1 year warranty
