I just bought two of these and I have them hooked up to a Brutis Hifonics 1600 watt mono amp. So yes I have them wired down to one ohm. After having my amp turned at about half way and after seven days they both stopped working . I have never in my life seen speakers smoke before this was a first. Yea they sound great but in my opinion the rms is not true or they're not so durable. I will give them one more try cause they sounded great!! Maybe I should only turn my amp up a quarter way till they break in....lol
