About: Kicker 47KPB1 21" Bluetooth Powered Speaker System

Covered in tough, powder-coated aluminum, the KICKER KPB1 21-inch PowerBar includes four mid-woofers and two titanium tweeters that fire up the outdoors. This IP66-rated system is driven by a 150-watt power plant, and the included 3.5mm line-output connection lets you add more amplifiers for an even bigger sound system.

A completely self-enclosed system, KICKER PowerBars do not require a head unit. Connect sources wirelessly via Bluetooth® or a full-range AUX stereo input, then control it all with the included steering wheel-mounted wireless remote. Four DSP-controlled EQ presets are easily accessible via oversized buttons in the center of the PowerBar.

Enabling KICKER’s Broadcast Mode™ wirelessly connects numerous PowerBars together, allowing everyone to enjoy the same music at the same time while on the trail, stopped at the campsite or gathering around the campfire.

The included bracketing lets you quickly mount the PowerBars on a 1.5”, 1.75” or 2” round tube, or you can mount on a 0.75”, 1” or 1.25” square tube.
