tommyk clamped his 2 strapped at 4 ohm load after rise and got close to 2000 per amp at around 12-13 volts
just ask him. they do rated at 12 volts and more at 14
they are not high current amps and they have nothing in common with hifonics boards at all.
if you email sic he will tell you the same thing
i will be buying 4 2000's very soon
as well as 2 4125's
