Our customers rave over the pushable on/off knob which turns your amplifier ON/OFF while driving. Feeling under the weather with a headache? Driving your kids to school? Want to listen to a podcast? You probably don’t want your sub(s) booming away in the background - push the knob and your amplifier will turn off. This is impossible with 90% of factory bass knobs on the market. By default, your amplifier will turn OFF with your vehicle.
Lastly, you can adjust the voltage display to be 100% accurate with your system. Simply install the UNI-KNOB following the wiring diagram on the back of the packaging, hook up a voltmeter to the power & ground terminals of your amplifier, then adjust the set screw on the side of the bass knob until the number on the UNI-KNOB’s voltage display matches the number on your voltmeter.
