I ran the amp 1 ohm stereo so I had to test per channel. I am honestly pretty amazed about it
20.4 ampsx 45.8 volts so 934.32 RMS per channel so 1868.64 RMS with imp rise 2.25 per channel so 4.5 ohms basically bridged and still did 1868 watts ... also to top it off!!! Dropping to 11.8 during test!!! It is rated 3000 at 2 ohm mono and 2000 at 4 ohm... And I got over 1900 at 4.5 at 11.5 so I am pretty sure this amp does rated and maybe then some. Now I am sure distortion rates were high but for what the amp costs. I did have a problem with it clipping out on my twice while driving on high freq but i am going to cut it some slack for now. I have a battery in the rear But I have cheap 4 gauge going from batt to amp and I am using a so so grounding point which I have the battery grounded there with 4 gauge and 4 gauge from the battery to the amp so perhaps it is getting some restriction.
