It was ok for the first few months and then i decided to try and run it at 1 ohm, played for about 3 minutes and that was it lol. I was a little disapointed in the amp though, was expecting more. But i never had a 1600 watt system before either at the time. Even with my short lived hifonics amp 2200d i was disapointed. Much better than the orion but still want more lol. I might as well just jump ahead and save myself the misery and go for a 10,000 watt amp and be done with it.
