Marine Subwoofers Information

Marine subwoofers are key to any outdoor sound system because a sound system needs bass and volume to overcome background noise. These subwoofers were created to be ideal for outdoor applications, with marine technology which was invented to protect audio equipment from rain, moisture and sun rays. Most marine subwoofers are specially designed for marine vehicle installations.

Most marine subs are fashioned with waterproof rubber mounting gaskets to prevent deterioration. In addition, most marine subwoofers are built with special materials that are less susceptible to corrosion, such as gold plated terminals and stainless steel. The lead connections are usually insulated to guard against weather and water. The electrical components and magnet also are built with hard plastic covering to prevent wear and tear. Marine subwoofers typically have plastic grills to prevent weather damage or to protect the cone from impact. Most are UV resistant to prevent the color from fading and the general aging of the subwoofer’s appearance.

We also carry marine powered subwoofers as well as enclosed marine subwoofers. Enclosed subs are either powered (do not require an external amp) or unpowered (require an external marine amplifier). Among these enclosed marine subs are bass tubes, which are water resistant enclosures. The unique cylindrical bass tube design saves space, and weather resistant mounting straps help keep your bass tube secure in spite of harsh weather conditions. Also be sure to check out our top marine subwoofer brands, such as Kicker Marine Subwoofers, Bazooka Marine Subwoofers, and MB Quart Marine Subwoofers.
