The optional RUX-KNOB2 remote bass control knob plugs right in to the Alpine Amplifiers for quick direct subwoofer control to make bass adjustments on the fly.

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.

Get full control over your amplifier, conveniently from inside the car. With the RUX-KNOB2 installed inside the vehicle cabin, easily adjust the bass gain of your amp while seated inside.

The RUX-KNOB2 comes with a 5 meter cable that simply plugs into your amplifier.
