The marine-grade ECOXGEAR® Sound Extreme Speaker Bar boasts a patent-pending IP66 highly water-resistant enclosure for 100% waterproof, dirt-proof, dust-proof, adventure-proof performance. This sound bar for off-road vehicles, boats, and more pumps out an incredible 500W of your favorite audio from 8 rugged speakers: 2 tweeters, 4 midrange, and 2 side-mounted woofers. 2 internal, independently sealed cavities provide true left and right stereo sound. Built-in Bluetooth® 5.0 lets you stream your favorite audio wirelessly from your compatible smart device. EcoCast lets you connect up to 50 sound bars together or to any ECOXGEAR speaker (not included). Integrated onboard controls let you take charge of your listening experience. A built-in microphone accommodates handsfree speaker calls. Multicolor LEDs backlight all 8 speakers, with the optic to sync to music, display solid color, or stay off. A rear-facing LED can turn on separately from the main LEDs. A waterproof 12V auxiliary power-out connection lets you connect directly to your vehicle's battery. Waterproof aux input plays audio from a wired device, and the waterproof aux output lets you daisy-chain this ECOXGEAR sound bar to other wired speakers. The waterproof 5V USB output even lets you charge your phone or other USB-powered device. Integrated mounting brackets provide multiple mounting options, and the long-range RF remote control keeps you in control of the lights and audio functions.
