If the line level to the sub remains at 10 all the time, how can the volume on the sub increase just because the volume on the receiver is turned up? The volume on the receiver increases the watts to the speakers hooked up with speaker wire, not a coax cable.

I'm going home, I'm hungry. Sorry for the dumb question.
