All Marine Amplifiers Information

Marine amplifiers are the perfect addition to your boat and will amp up your sound system's volume. In the marine environment, it is important that you have enough power to drown out background noises. A marine amp will provide plenty of power for your marine speakers and marine subwoofers and they are built to last in the marine environment, as marine amplifiers can withstand light rain, moisture and damaging sun rays.

Marine audio amplifiers protect your audio system’s power from moisture and humidity with gasket-sealed covers for the top-mounted controls and endcaps. The marine amps feature rubber caps to cover the RCA inputs, silicone boots to shield the fuses, and their circuit boards have corrosion-deterring conformal coating.

We carry marine amplifiers in monoblock, 2-channel, 4-channel and 5-channel models. In addition, they come in variety of power output capabilities. Some popular brands for marine amplifiers are Boss, Kicker, and MB Quart. Shop now!
