In the interest of sharing (and in adding more searchable information to the board), why don't you post an explanation?

I think I know, but I'm no expert, so I could be wrong.

I don't have the time to write out an explanation of how to set an amp's gain. However there is plenty of info on the net.

This is how I set the gain on all my installs

Here, follow this interactive tutorial from JL...

And here is one rule as well after watching that, say you have a 4 channel amp, 4x100 at 4 ohms. To figure out its optimal voltage, you do the watts times the ohms (100x4) and find the SquareRoot of that (20). So you would set your input voltage to 20.
