Ok thanks for the quik reply. Just seems weird to me because one is putting out 200 watts per channel and the other 400.. so i thought they should have different AC voltages. Does the tech answer have something to do with the fact that one is at 4 ohms and the other at 2 ohms? what i mean since the resistence is lower on the 2 ohm the same AC voltage goes farther or something. I just dont understand how the same AC voltage can be 200 watts, and 400 watts, unless it has something to do with the resistence that the load is meeting when it gets to the speaker. I hope what im trying to say makes some amount of sense.
