Sometimes the signal level of the subwoofer out is not enough to turn the sub on reliably, particularly if the level settings in the receiver have been adjusted so that the sub level is below 0dB. If that is the problem, it is easy to fix by raising the sub level in the receiver and turning the level down at the sub using the level control.
Does the sub "never" turn on, even if you are playing some bass heavy music fairly loud ?
