Ready to accessorize your tailgate? If you’re setting up a campsite or tailgating at the big game, unload your music closer to you – and you don’t want to leave your truck running in order to play the stereo – the available Kicker MultiPro Sound System accessory can be quite handy.Designed expressly for Sierra 1500 models with the MultiPro tailgate and offered and installed by Jim Ellis Buick GMC, the Kicker MultiPro Sound System is a 100-watt exterior audio system neatly integrated within MultiPro’s inner gate panel. The system incorporates two 4" coaxial drivers, a compact amplifier and controls, a USB port for device charging and flash memory playback, along with full Bluetooth streaming compatibility.The MultiPro Sound System is integrated into Sierra’s MultiPro Tailgate, but it operates independently of Sierra – the truck does not need to be on or running for the system to function, and a low current draw allows it to play for hours. The system also uses a tilt switch to automatically power down once the inner gate step is folded shut and the tailgate closed.Like Sierra and MultiPro Tailgate itself, the sound system was designed and extensively validated to ensure it remains rugged and ready. Kicker’s expertise in creating audio components and speakers designed for boats, ATVs, motorcycles, and other vehicles exposed to the elements was leveraged in ensuring the components in this system can live up to the demands of a pickup truck’s box. The MultiPro Sound System is further protected by an ABS custom baffle, which is fully gasketed to prevent moisture and dirt intrusion. Additionally, the system’s wiring harness, connectors, and plugs are weather resistant for further protection.
