The built-in Class-D amplifier delivers 150W RMS and 300W peak power with less than 1% distortion, providing strong, clear sound wherever you travel.

A variable 3.5 mm aux-out allows expansion with powered speakers or subwoofers controlled directly from the bar. Three gain settings adapt the sound to different systems. The soundbar also supports JBL Click, an optional Bluetooth remote that attaches to a steering wheel or handlebar for track, play and volume control without using your phone.
