This amp is an overall reliable and cool operating unit with a very high initial quality. It is 2 ohm stable, not 1 ohm, however I’ve run it at 1 ohm with no bass heavy tracks. With a bass heavy track it’ll run smooth with the bass boost up at 1.67 ohm no problem. Overall, looking at the current pricing under $500, this is the most powerful amp at 2400 watts RMS(my birth sheet is (2570 Watts). 8 out of 10 rating.
