2 channel amp gain question.

[sayhuh?]

Dumb question, When setting the gain with a DMM on a two channel amp and the amp is 500x2 @ 2ohms, do I calculate just for the 500 rms or the total, which will be 1000 rms?

Thanks in advance.

The RMS on one of the channels.

Werd. I thought that, but when unsure, ask. lol.
