JBL Black Stadium Powersports Marine Soundbar Speaker System - JBLU4000BLK

Legendary JBL pro and home audio performance is now available for the great outdoors. The new JBL STADIUM UB4000 Powersports Soundbar is designed for UTVs, boats and other personal and family vehicles built for fun and recreation. Take the wheel or helm and experience the sound of powerful JBL rollicking sound. It's also equipped with a super flexible mounting system that fits any size roll cage and will take a 10G shock and stay put. You can also separate the soundbar into two speaker towers to optimize sound quality for any installation. There's a GoPro shoe for an action camera to share your finest moments—like how you look when you hit your first hole in one. With JBL sound leading the way, you'll find yourself in the cockpit ready to do things you've never done before—be it on land, sea or a long green fairway.
