8” Marine Amplified Bass Tubes



- test 2


As far as all-in-one solutions go, you simply can’t beat the 8” 100-Watt Marine Dual Amplified Bass Tubes. Easy to install, these amplified tubes are the perfect way to upgrade your boat’s audio system. They have a 100-watt, 2-channel amplifier built right in and coupled to a 8-inch dual voice coil (waterproof) subwoofer. The built-in crossover removes the high frequencies the woofer cannot play from the signal, so you get exactly what you need: crisp, clean bass, nothing more. The end result is seamless integration, both electrically and audibly. Made with stainless steel hardware, all our marine tubes are salt, fog and UV certified. They come with weather-resistant, Velcro-reinforced straps that allow for secure mounting. Removal is easy, too! If you want a flasher look and more permanent mounting solution, the optional chrome-plated UMS brackets are perfect.
