Another question about setting gains with a DMM

Yep, another question about setting gains with a DMM. I used to know the formula when I did my monoblock: Sq.Rt. of watts x Ohms (sq. rt. of 1776watts = 42.14 x 1 0hm= 42.14vac) Correct?

Now I'm doing my gains on my a/d/s 8 channel and am not sure how to calculate it since I have all 8 channels bridged down to 4 channels. The amp is rated for 8x60rms@4ohms and 4x180 bridged @4ohms. Their is one gain control for each pair of channels for a total of 4 gains. Basicaly this is more like 4- 2 channel amps under one housing.

Is this correct? Sq. rt. of 180w=13.41 x 4 ohms = 53.66volts A/C

I believe it is the square root of 180 x 4 = 26.8v

I use this site to get my info. Just plug in your watts and ohms to get your voltage.

Got it! Thanks for the info.
