Best Marine Amplifiers by Wet Sounds: Our Top Picks

When designing the ultimate marine stereo system, we know how easy it is to focus on the speakers and the subwoofer. After all, these components are responsible for the sound quality and texture. Yet an amplifier is just as critical for any marine audio system. With the right amp, it's possible to power up a boat stereo, crank the volume, and let the good times roll.

Curious about the most important components of an amp? When looking for the best marine amps, we make a point of seeking out these specifications:

• Channels: Confirms how many separate power sources an amp has. Each channel generally supports one speaker, so more channels equals greater speaker potential.
• Power Output: Indicates how loud the music can get. More watts mean louder sound.
• Total Harmonic Distortion: Reflects how much the amp affects the sound color. A lower number means less distortion.

So what's the best marine amplifier for a sound system? Take a look at this list of our favorites.
