The formula is correct but the page is a bit missleading. In order to know what your amp can do you have to rule out the HU and amplifier state of clipping. If you turn the HU to full power, you will only be reading the clipping of the outputs. The signal could even be lower than your max power since a clipped signal can very erratic depending on the amount of distortion. Once you have set the HU and amplifier gains correctly, you can raise the power the volume to just under clipping. This is pretty close to the maximum wattage the amp will produce. Once again, ignore any clipping. As for the amps rms, there is no real formula. This will all depend on the particular amp.
