Just noticed that formula for power is different than what I saw else where. Do you mean E*2/R? The other one I saw was V*V/R where V was the rms voltage.

You measure 5 volts out when it begins to clip5*5/8ohms=3.1 watts
If you want to check freq response doing manual plots, you can do a frequency sweep starting at 5hz ending at 20K and plot it on paper.
Your meter needs to have a good freq response to do this. Simply plot the voltage as it drops across the sweep. You could simply sweep 5hz, 10hz, 20hz, 30hz, 40hz, and then start at around 12KHZ up to 20KHZ

He means the square of the RMS voltage, divided by the resistance.
