Power is V^2/R. An increase in voltage is also associated with an increase in amperage, which exponentially affects power. Think of it like water pressure: If you double the water pressure coming out of a hose, you'll also get more flow at that higher pressure.

Simpler way, that takes into account manufacturing error of the amplifier:

Note: Use this only if you don't have access to an oscope/dd-1. It's very dirty.. But better than doing it by some other arbitrary metric, or by doing spreadsheets (especially if the amp in question is over-rated)

1. Play a square wave at max gain (please disconnect your drivers). This will measure the peak to peak voltage of your amp - i.e. the rail voltage. Let's say... You measure 60v.

2. Turn everything down/off. Take that number you just got, and convert to RMS voltage by dividing by sqrt(2). So you'd take 60v/sqrt(2) = 42v

3. Play a sine wave at your desired amplitude (say -5db) and turn the gain up on your amp until your output voltage is 42v. Don't get excited and go higher - that's just clipping.

4. Hook your equipment back up

I get it now I own a dd1+ tho so I just needed to add that to my knowledge bank
