Its rated at 2 ohms not 1, do you really think a 2 ohm amp would be .5 ohm stable for daily? I'm sure it could burp at that, but it can't do that daily. Its a great amp, and it puts out its power at 2 ohms, I've heard different opinions on whether its 1 ohm stable. This is a great amp for anyone needing some big power, someone buy this.
