Theoretically speaking with a 40A fuse rating, this amp is NOT capable of producing more than 65WRMS of power per channel at BEST....!!
Better buy a 65WRMS x 4 Sony amplifier from Pakistan.
Its an unknown brand woldwide and the power they mentioned is B.S, so it must be a shitty amplifier.
P.S. They havent mentioned SNR, THD, Damping Factor and above all its not CEA-2006 compliant cos CEA-2006 never mention maximum wattage they always mention RMS wattage of an amplifier.
Verdict:
its a fake/crap amplifier, DONT BUY IT
