Here's a bump for ya.
Rated at 2600 at 2 ohms and 12.6 volts
3000 at 2 ohms and 13.8 volts.
Why would you need to run this amp at 1 ohm ?
I own a few of these amps and there is no better bang for the buck. The amp draws far less current then any other amp in that power range or price range and will kick the crapout of amps more then 2x's it's size. I have tested this amp vs a number of other amps with close power rateing and have yet to find 1 that is louder.
For a BURP I have run 1 of mine at .35 ohms and seen 4400 watts RMS clamped. That was at 12.9 volts.
I have straped a pair and clamped OVER 6,000 watts at 12.8 volts and 1.4 ohms usable all day long.
Who ever buys the amp will not be sorry as these are BAD A$$ amps.
