Best Marine Audio Gear of 2020

Best Marine Audio Gear of 2020

Last updated on November 10, 2020

Our picks for this year’s best-of-the-best marine audio equipment.

Rule #1 about buying audio equipment for your boat: if it’s not specifically made for life on the water, do not take it to sea. True marine audio gear is water-resistant, fog-proof, salt-proof and UV ray resistant. Marine receivers or head units come with coated circuit boards that don’t rust, rubber caps to cover all open inputs, and gasket sealed covers for all controls, knobs, and end caps. Marine speakers and subwoofers are built with plastic cones and rubber surrounds and come with weather-resistant mounting hardware. Anything less than true, marine-grade audio gear, and you’ll be tossing it before the season’s over. Rule #2: unless you own your own cruise ship, smart and efficient use of cabin space is critical, so look for an audio system you know will fit… while giving you the best possible bang for the buck. 

Below are our picks for the best of the best by category, as chosen by experts - one of whom is both a life-long sailor and a recent inductee into the Consumer Technology Hall of Fame: our own founder, Bob Cole. So… you ready? Let’s shove off…

Why it won

If you’re looking for a high-performance stereo meant to deal with the rigors of boat life, look no further than Sony’s MEX-M100BT marine-grade CD receiver. Packed to the gills with features and ready to tackle the open waters, you’ll be thrilled with the looks and performance of this stereo. Like what kind of features, you might be asking? Well, besides the onboard CD player and AM/FM tuner, the MEX-M100BT boasts Bluetooth for hands-free calling as well as audio streaming, USB and auxiliary inputs for connecting your favorite audio devices (think iPhones, iPods, Android smartphones, etc.), and SiriusXM compatibility (optional tuner and subscription required).

If you’re planning to make this marine receiver the cornerstone of an awesome sound system, it has 5-volt front, rear, and subwoofer outputs for additional external amplification. And speaking of amplifiers, you should take note that this Sony has a strong Class D amplifier built-in, capable of 40 watts per channel of continuous power output, which will power just about any pair of marine-grade speakers with ease.

Rounding out the feature list of the MEX-M100BT are easy-to-see buttons and a large volume knob for quick and convenient control of your music.

#3. The Best Monoblock Marine Subwoofer Amplifier for Boats: Kicker 45KMA6001 Monoblock 600-watt Marine Amplifier



Why it won

The marine-grade 45KMA600.1 from Kicker is a monoblock (single channel) amplifier designed to thrive in the severe environment that a boat can (and will) present. Its Class D architecture keeps the chassis compact, so it will tuck away in a cabinet somewhere on your craft, and running coolly throughout your voyage.

This little monster is capable of pushing out a remarkable 600 watts at 2 ohms (400 watts at 4 ohms), so it can provide enough horsepower to drive just about any subwoofer you have (or are going to get). In case of exposure to moisture, rest assured this amplifier can handle it. There is a conformal coating on the internal printed circuit board (PCB) as well as corrosion-resistant connectors at the power and RCA inputs in addition to the speaker outputs. The onboard tuning knobs and switches are concealed and protected behind a cover plate that contains a rubber gasket to repel against water intrusion. Kicker designed this amplifier for marine use, yes, but they also designed it for years of enjoyment. So what are you waiting for?

Watts: 400 watts at 4 ohms, 600 watts at 2 ohms | Dimensions (in inches): 2-5/16H x 7-1/8W x 8-1/16L

#4. The Best Value 10” Marine Subwoofer for Boats: Kicker 45KM104 10" 4-Ohm Marine Subwoofer



Why it won

If you’re looking to take your boat’s audio to the next level, you have to check out the 45KM104 10” 4-ohm marine-grade subwoofer from Kicker. What makes a subwoofer marine-grade you might be asking? A bunch of things. For example, the polypropylene woofer cone repels water easily enough, as does the hardy rubber surround that connects the woofer cone to the chassis of the subwoofer. The motor structure is completely encased as to avoid accidental contact with water, too. Lastly, the terminals (where the speaker wire connects from the attached amplifier) are completely covered by a removable cover.

One must remember that water isn’t the only obstacle that speakers/subwoofers have to be wary of when they reside on a boat: UV light from the sun and salt can be just as detrimental as water, but Kicker thought of this and the materials used (like that polypropylene and rubber materials mentioned earlier) help ensure that you receive the best-possible sound for a long time. This subwoofer is best suited with about 250 watts of continuous power and in a sealed enclosure that measures approximately 1.00 cubic feet of internal volume (or a vented enclosure with 1.25 cubic feet of internal volume). The 45KM104 doesn’t require a lot of power or a lot of room to make one heck of an impact on your audio system! Looking for a free air 10” subwoofer instead? Check out Kicker’s 45KMF104.

Woofer Size (in inches): 10" | Power Handling: Up to 250 watts RMS, 500 watts peak | Frequency Response: 30Hz –500kHz | Impedance: 4 ohms

#5. The Best Value 12” Marine Subwoofer for Boats: Kicker 45KM122 12" 2-Ohm Marine Subwoofer



Why it won

Kicker’s 45KM122 12” 2-ohm marine-grade subwoofer is the perfect addition to any boat’s audio system. The polypropylene woofer cone is married to the chassis of the speaker via a durable rubber surround. Both materials were specifically called out because they do quite well in the harsh marine environment which includes, but is certainly not limited to, water, UV light, salt, and fog exposure. You want to be sure that if you’re going to be adding something to your boat that it’s designed to last in this atmosphere and the Kicker 45KM122 certainly can! The encased motor structure and terminal areas also help improve the longevity of the subwoofer, too.

When it comes down to power handling, this Kicker subwoofer handles up to 300 watts continuously and requires a sealed enclosure of around 1.25 cubic feet of internal volume or a vented enclosure of around 1.75 cubic feet of internal volume. You’re going to be thrilled with what this subwoofer adds to your favorite tracks and it will keep bumping all day and all night! Looking for a free air 12” subwoofer instead? Check out Kicker’s 45KMF122.

Woofer Size (in inches): 12" | Power Handling: Up to 300 watts RMS, 600 watts peak | Frequency Response: 30Hz –500kHz | Impedance: 2 ohms

#6. The Best Loaded Subwoofer Marine Enclosure for Boats: JL Audio 8" 4-Ohm Marine Enclosed Subwoofer System



Why it won

If you don’t want to be bothered by cutting a hole to fit a subwoofer somewhere in your boat, JL Audio’s M6-8FES-Gw-C-GwGw-4 might be the answer to your dilemma. This slick, gloss white enclosure not only looks at home on any boat, it also houses an 8” marine-grade subwoofer that can handle up to 200 watts of continuous power being thrown its way. Measuring about 15”W x 14-1/2”H x 10-1/2”D, it’s sure to fit just about anywhere you have a little bit of unclaimed room.

A stylish, yet sturdy, gloss white grille protects your investment from accidental harm. The enclosure that JL Audio built for this subwoofer system is tuned for the open-air environment that boats present. The enclosure’s finish, like the subwoofer itself, is designed to stand up to the water (salt or fresh), UV light, salt, and fog that is present out on the water. Rest assured that JL Audio wants you to enjoy this subwoofer for as long as you own that boat (and maybe even the next boat, too!).
