My new Xenon amp (x600.1) came with two birth sheets. One is a 8.5 x 11 printout with the amp's serial number, a graph, and some typed efficiency, current draw, etc numbers which states power is 842.35 watts. The other is a half sheet sized printout with handwritten model number, checks in the "passed" boxes, and a handwritten tested power of 617 watts. Both state power at 14.4 volts and 4 ohms. Which one is the accurate one? I would assume the one with all the specific numbers catered to my specific amp, but I wanted to make sure.
