Talkin for the gain settin sticky

Here's the formula you'll need ...

Sqrt(Power*Resistance) = Voltage

(i.e. If you bridge a 4 ohm subwoofer to your amplifier that is rated to produce 100 RMS @ 4 ohms in bridged mode, you would want Sqrt(4*100) = 20 volts)

??? 4x100=400, where is the 20volts comin from? What am I missing? Somthing simple I know,but thanks for any help
