How To Choose A Marine Speakers – Buying Guide



When you’re buying your boat speakers, you need to ensure that you have the right sound output otherwise you won’t be able to hear it. Due to the surroundings that marine waterproof speakers will be used in, there are several challenges that top-rated boat speakers have to overcome.   

Being out in the open air, there’s nothing for the sound to rebound from and the audio has to be clear and loud enough so the sound waves can travel directly to you. Another thing that can affect the sound getting to your ears is the wind and noises in the surrounding. 

Whether you’re on a boat with the hum of the engine or at a beach with the crashing of the waves, the sound should be powerful enough to pierce through the wind and noises. The best marine-grade speakers are designed to overcome these challenges


With marine audio speakers, durability is a top priority. These speakers will be exposed to the elements and seawater and shouldn’t fail at the first interaction with saltwater. Make sure you buy marine grade speakers designed with this purpose in mind. All speakers for your boat need to be at least water-resistant. Waterproof marine speakers that offer an extra edge of protection. 

Salt is the best exponent at creating rust. You want to ensure the speaker you’re considering are rust and corrosion resistant. The sun’s UV rays can damage all electronics like diving computers. Speakers that can resist UV rays are ideal.

Ease of installation

Once you’ve chosen the speakers you want, they’ll need to be installed. If you’re replacing existing speakers, then this is going to be a simple task that you can most likely do yourself. Be sure you measure your speaker holes to determine the size speaker you need.

If you’re installing a new system, this might require more expert installation as holes will have to be cut out. If you don’t want to cut into your boat, you can get the best portable boat speakers that wouldn’t require installation. If you’re installing numerous speakers around your boat, it can get tricky and the best option would be to find a professional to install them.

Use of Speakers

Before you buy speakers, you need to determine what you’re going to be using them for so you can get the best boat speakers fit for the purpose. What activities will you be doing on the boat while the music is playing?

If you’re going to be using your speakers while fishing on calmer waters, loud volume won’t be a priority. If you’re going to be waterskiing, you’ll want speakers that have a much higher wattage and volume.  


The location of your speakers is important to get the best sound possible. Speaker placement is even more important when you’re on a boat because of all the things that can interfere with the sound. It could be that you’re simply upgrading pre-existing speakers and know exactly where you’re going to put them.  

If you are installing new speakers from scratch, then you want to pick the spots that are going to give the sound the most coverage. Picking the wrong location could give you a hole in the side of your boat that you don’t need and will regret later.   


The location of your speakers is important due to the directionality of the sound. Most speakers only play sound straight out in front of them. In a closed room, sound is enhanced when it bounces off the walls and other surface. Unless you’re below deck, you don’t have that luxury with speakers on a boat. Therefore, you want them pointing into the space where you need to hear the sound. 

Another consideration in terms of the direction of your speakers is stereophonic sound. When music plays out of at least two speakers, different sounds can be playing in different speakers. Therefore, you need one speaker on either side of you to get a much better and richer sound.  

Magnetic Shielding

Speakers contain magnets and the magnets need to work without interference to give you the rich sounds that you’re looking for. The magnets in speakers can also interfere with the functioning of devices such as compasses. If you’ve to install the speakers near the boat’s compass, ensure the speakers you choose have magnetic shielding so they won’t interfere with the compass or anything else onboard. 

Water Resistance

Of all the features you will want to look for in a marine speaker, water resistance is one of the non-negotiables. If you’re installing speakers onto a boat, then they simply have to be water-resistant.

Being water resistant means they will still work should they be subjected to the occasional splash or rainfall. If you’re looking for a higher level of assurance or are on a boat that might be subjected to a higher level of contact with water, a waterproof speaker is the best option.

If you’re looking for the best boat speakers to be as loud as possible, choose one with a high wattage. If you need your speakers to reach a higher volume, then it might be worth investing in an amplifier. 

The lack of hard objects for the sound waves to bounce off, the wind and the background noise can all play a factor in not getting the sound level you want. Getting an amplifier will allow you to turn up the volume and play the music as loud as you want.

Sound Quality

Look for speakers with a high decibel rating as the higher the rating, the greater the speaker’s ability to convert power into sound. 2-way speakers are better than 1-way speakers as they are able to produce great sound over a range of frequencies.

Most of the speakers we’ve reviewed here are 2-way and well-known for producing top-quality sound. Aside from the decibels, frequencies, and power, it’s important to read marine speaker reviews and check the ratings to see what others are saying about the speakers.

Q: Do I Need A Receiver?
