My pulseaudio mixes the left and right channel to a (I suppose) mono channel and then sends it to the sub. Although the subwoofer connector features 4 contacts (TRRS connector). I think for presence detection or dummy load. I unscrewed the plastic barrel and found two wires wired to the voice coil and the two others are connected with a resistor.
