About the Alpine RUX-KNOB.2

Tweak the subwoofer volume from the driver's seat
The RUX-KNOB.2 remote level controller works with Alpine's amplifiers so you can manage your bass level from the front of your vehicle. This handy little knob adjusts your amp's level from its set maximum volume all the way down to virtually "off." Since it adjusts level and not "bass boost," you'll maintain the same bass tone as you turn the volume up and down. You can control multiple amplifiers with a single remote by adding a standard phone cable splitter (not included).
