Listen im not arguing about the results and Peter has tested those amps more then anyone. When we tested them They got loud at 1 ohm strapped louder at .7 and the loudest was at .5 but they werent stable and you had to roll up very slow not to go into pertection. The amps are lethal at .5 strapped over 2 db gain from 1 ohm strapped but i couldnt keep poy of protection. The rise in my car was double .5 per amp when strapped 1 ohm after rise and the same with .35 and .25 wich was unstable.
