these amps work there best at 18 volts,they happen to get around 8000 watts or so with enough voltage droped into them.whats nice about these amp they are very relable and make a ton of power at a cost efficent price. but to make them work at 18 volts the clipping protection and the voltage surge protector needs to be bypassed.ive used 4 of these amps in my setup. against 4 of the soundstream xxx 10,000 watt amps and i hit the same number on the my suggestion to anyone out there using these just put a kinetik hc 2400 battery next to the amp and u can make great power at a very affordable price
