E=IR, IIRC, where E=voltage, I=current/amperage, and R=resistance. So your statement about more resistance = higher voltage would seem to be true, but I'm pretty sure that more Ohms is more resistance.

Then again, we're talking about power, so P=IE, or P=IIR, so, still, more resistance equals more power.

But as I look at amp specifics, I am seeing things like ``Watts/channel @ 4 Ohms = 50'' while ``Watts/channel @ 2 Ohms = 75''. So there's something I'm missing.
