[QUOTE="TeenWolf, post: 1004766, member: 561987"] 1 x 500 watts @ 4 ohms (12.5 volts, 1 x 750 watts @ 4 ohms (14.4 volts, 1 x 1000 watts @ 2 ohms (12.5 volts, 1 x 1500 watts @ 2 ohms (14.4 volts, Notice how the general rule applies when all other variables are constant (ie. volts)? The birthsheet states the amp was measured 1 X 1159w @ 2 ohms. Don't you think that they would get a higher measurement than 500w on the 1 X 500w @ 4 ohms? Which supports the general rule? And don't you think the amp birthsheet would be inaccurate after the amp has experienced some age, wear, and tear? There's no doubt that MTX produces great amps that will exceed their rated output, but you need a standard format to judge and compare its performance to other amps. We know that the rated RMS output is a minimum, but trying to determine how far it will go beyond that is speculation and will vary. Maybe you give the birthsheets a lot of weight, but I don't. I didn't even read the one that came with my MTX amp. I just look at the rated RMS and know that it will not fall below this, which I can compare to other amp rated minimums. P = E2/R Where P is watts, E is voltage (squared), and R is resistance. If E stays constant and you double R, then P has to be reduced by half. If you take two measurements from a birthsheet: one at 2 ohms and the other at 4 ohms, with all other variables constant, then ohms law will apply. [/QUOTE]
