"The Wet Sounds Stealth AS-Series Powered Subwoofer Enclosure provides the ultimate all-in-1 solution for bass in your ride! The tough and durable molded polyethylene housing is designed to handle any harsh environment while providing superior low-end output. The built-in Class-D amp is sealed against moisture and dirt for extra protection and power. The Remote Turn On Wire connects to the remote out on newer sound bars, but if a user has an older sound bar, the sub has auto sensing as well to turn on automatically. All Stealth subwoofers have been designed with the correct connections to be ""plug and play"" making the installation incredibly easy on Wet Sounds Stealth Ultra HD sound bars, but it will work perfectly with another brand or an older Wet Sounds Sound Bar as well. The physics of sound tell us that any subwoofer increases its output when allowed to ""load"" into a wall, corner, or some other structure. Since every vehicle and application is different, the experts at Wet Sounds suggest you experiment and move the subwoofer around to find the optimal position. Rotationally molded polyethylene housing withstands harsh environments High-efficiency Class-D amp is sealed against moisture and dirt Easy plug and play connection High-excursion subwoofer driver is computer matched to the enclosure Remote control included Thermal and over/under voltage protection Stainless steel mounting hardware Durable aluminum grill Auto or manual turn-on function"
