Alpine PWE-S8-MRN 8-Inch Weather-Resistant Powered Marine Subwoofer Enclosure with 240W Class-D Amplifier
The Alpine PWE-S8-MRN is a compact, weather-resistant 8-inch powered subwoofer engineered specifically to deliver deep, impactful low-end punch to marine and powersports vessels. Housed in an ultra-durable, IPX6 weather-resistant cast aluminum enclosure, this self-contained bass solution is built to withstand direct sun exposure, saltwater spray, high humidity, and heavy vibrations. Designed to fit neatly under boat seats, inside storage compartments, or behind cabin panels, it provides a strong, beefy solid foundation for your marine audio system without sacrificing valuable deck space.
At the structural heart of the PWE-S8-MRN is a high-excursion 8-inch quad-coil woofer paired with an integrated 240-Watt peak (120W RMS) Class-D digital amplifier. This high-efficiency active design generates tight, distortion-free low frequencies with minimal current draw on your boat's marine battery system. Outfitted with versatile high-level speaker and low-level RCA inputs, auto turn-on sensing, and an included wired remote bass level knob, the Alpine PWE-S8-MRN offers effortless installation and immediate, on-the-fly bass adjustment directly from the helm.
