There are guys (Team Kicker) on CA.COM that can answer this. I had asked this question before actually called tech support at Kicker and was told that the gain would be minimal due to the power supply regulation. He said (think it was Mitch) that I would gain more in heat than anything and if anything it would be only a few hundred watts but the amp would eventually fail. Now I know there are mods that can be done but you will need to ask Team Kicker. I had a strapped set of Kicker sx1250's running at 1ohm and you could not tell a difference. Had a single running at .5 ohm and the same thing. Now if I run my IA 40.1 at 1 ohm then at .5 there is a very audible difference, like going from 12V to 16V system. One thing you will notice is that the draw is immence and if you do not have the power it will pop. Polo.
