Marine Amplifier Systems

Increase power, volume, and quality on the open water with a marine amplifier. Waterproof marine amplifiers boost your system and help drown out engine noise, wind, and even other boaters. They also ensure a clean, low-distortion and accurate sound so your favorite music sounds even better.

Whether you have more speakers that requires a marine 2 channel amplifier, or only need a small marine amplifier, with brands like Kicker, JL Audio, Rockford Fosgate, and Kenwood, finding a marine waterproof amplifier to power your fun on the water is as simple as a day on the water. These amplifiers are specially designed to withstand the harsh marine environment, with features such as waterproofing, corrosion resistance, and UV protection. This ensures their durability and reliability even when exposed to saltwater, humidity, and extreme temperatures.

Performance Boat Amplifiers

A small marine amplifier will power the sound system on your smaller craft or a large amplifier will let every passenger on pontoons and yachts enjoy fun tunes. A marine 2-channel amplifier is sufficient for many full-range speaker kits, and we also have mono boat amps for a simple subwoofer boost. Four-channel and five-channel marine amplifiers are also available to run component speaker systems and add even more power to your system.

If you’re on a budget but still want impressive audio, browse our selection of refurbished marine amplifiers. They’re certified to work as good as new at a much lower price. The exact amp you’ll need depends on your boat speakers, so be sure to check their total power requirements before purchasing. A marine amplifier is also a must for UTVs, motorsports and other times you’ll be listening to music in severe conditions.
