Turn the gain knob on the back of your subwoofer up and re-run MCACC. That will raise the subwoofer pre-out level on the avr after MCACC is ran again.. Continue to do this until it reads a value between -3 to 0.
BlueJays, if I increase the gain as you call it (I'm assuming you mean volume), that will make the sub louder. Won't that lower the db gain on the AVR because I could over power the other speakers? -11db is less loud than 0 db, right? Every 3db loss is half the power, at least in log math.
