Uless voltage is stated specifically, all MA Audio amps are are rated at 13.8v, according to their tech support. Only some of the MA Class X monoblocks are rated at 17v (2000D, 4000D) and these are also rated at 14.4v.MA Audio are tated at i think 17v
once the amp is driven past its rms power it will begin to distort and it all depends on the amp and how its made and with what was made, while driving a usamps into WAY more power that its rated it will likely go over the 1% THD level that the brutus is already rated at for its rms that doesnt even do.also you gotta look at the THD or watever. cuz you can run an amp much higher than the actual rating, but the distortion will be much higher.
