Engineered specifically for the marine environment, the 10 in MS-SW10 subwoofer makes the perfect complement to your Fusion marine audio system. The MS-SW10 has a water-resistant design and complies with ASTM standards for UV stability and salt/fog-resistance, ensuring sustained high performance during prolonged exposure to the elements. With 400 W peak power output, the MS-SW10 produces crisp and accurate bass. Install your MS-SW10 subwoofer with a Fusion amplifier such as the MS-AM402 (recommended) for the best sound quality and performance on the water.
