Would be 5 stars but after doing the math on my own. RMS watts it advertised it’s not true it’s about 1000 RMS watts less even though being hooked up to my 1300 RMS watts a piece subwoofers it’s still Powers them very very well without breaking a sweat doesn’t overheat stays cool to the touch and beats pictures of my neighbor’s wall two blocks down for the price of this amp it’s unbeatable well it’s unbeatable period Highly recommend you have no worries with this amp
