Power, power, power! Ever wonder why you can buy an amp for $50 that puts out 1000 watts? Easy... THEY LIE! Here's what I look at... the fuses on the amp. Engineers choose the fuse size... not the marketing guys. This amp consumes an upper bound of 60 amps total. At 13.5 volts, that would mean that the amp could continuous consume up tp 810 watts of power.
