The problem isn't the adjustment range on the sub, but the voltage level on the output on the receiver. Too high a + (it varies from model to model), and you run the risk of clipping (that is, having the voltage hit the max and hold there) during large LFE events when the receiver is also turned up loud.
If '0' consistently turns on your sub, then it is the best setting.
Alright....I will dial back to 0 and recal tonight when I get home - assuming we don't lose power from the impending ice storm. Thanks for the advice.
