We gave our boating experts one job:
Find the best and most popular waterproof marine stereo and review them.
Our review team researched at boat shows, interviewed owners for their experience and shopped around to glean some authority on the matter.
A marine stereo for your boat needs to be robust in the harsh maritime conditions. But it needs to provide a high-fidelity experience with features and convenience that makes them a better option than simple wireless, Bluetooth speakers.
The challenge of finding the right solution with the best value is not an absence of options but a flood of products.
Take note of what weatherproofing profile these products have and how much audio power they can produce in order to match the size of the boat and the speakers needed for it.

How to choose the best marine radio? | Buying Guide
We’ve just made your life a little easier by listing our top 15 marine stereos and to help you even further, here are 7 things to look out for when you go marine radio shopping:
1. Water Resistance
Since your boat will always be surrounded by water whether it’s on the marina or in the open sea, this is a no-brainer. It is important to note though, that the water exposure these products can handle will vary between simple resistance and waterproof.
However, most of them will withstand light splashes of water to rain.
2. UV Protection
Sun exposure can seriously damage your boat’s music system, especially if your dashboard is often exposed to the sunlight. So make sure you invest in a stereo that is properly designed to endure the UV rays on your controls, faceplates, display, and speakers.
3. Anti-corrosion
As much as we love to feel the sea breeze caressing our faces, seawater does not go well with the metal and electrical parts that make up your marine stereo system.
Therefore, for your boat radio to last longer, any metal should be rust-resistant and the circuit boards must have a coating against corrosion.
4. Sound Quality
In a marine environment, many things can prevent you from enjoying your favorite tunes: the sound of the engine, the waves, the wind, and the occasional loud seagulls are just a few of them.
Consequently, your radio needs to be powerful enough so it can drown out these noises and provide you with a clear and clean sound. Another reason why you shouldn’t install your car stereo on your boat.
Most marine stereos will have an amplifier built-in and they are, for the ordinary sailor, quite good and powerful. However, if you are very picky about sound quality or you’re a party animal who enjoys loud music, you might want to consider investing in an external amplifier.
5. Installation
Another aspect you need to check before buying your marine stereo is that it fits into your dashboard or into a pre-existing hole from a previous stereo. This is by far, the easiest choice or you might need to widen or shorten your existing space.
6. Expandability
A good set of speakers is a game-changer when it comes to boosting the quality of your sound. And although this topic deserves an entire guide dedicated to it, here are a couple of things you should keep in mind.
Be sure to check out that your stereo comes with a range of preamp outputs, which are essential for you to connect not only the amplifiers but also future subwoofers. The former is what delivers sound to the speakers while the latter gives you that perfect bass sound.
And just like you did with your marine stereo, make sure to get the right measurements of where you intend to place your speakers. This will prevent you from a future headache and will make the installation process a lot easier.
7. Additional Features
- Smartphone Compatibility: As you can see from our list, whether it’s through a wireless connection or through a cable, you’ll definitely find a way to integrate your smartphone with your marine stereo. The majority of them will have Bluetooth built-in, which is the most convenient option, but you can also connect your portable device through the USB port or the auxiliary input.
- Wifi Connectivity: While Bluetooth is extremely convenient and interoperable across virtually every device, there’s some quality loss. A Wifi connection maintains the virtuosity of sound better. These systems tend to be found on larger boats and they tend to cost a little more.
- Bluetooth Connectivity: The Bluetooth technology provides you with a range of functions such as playing music stored on your phone, access to music streaming services such as Pandora, Spotify, and Apple Music as well as hands-free calling, as long as your stereo has a built-in microphone. And since music streaming services have become the most preferred way to listen to music nowadays, this is quite a useful feature to look for.
- USB port & SD slot: This is another way to access your media files. Most marine stereos will come with a USB port that lets you play your songs straight from your flash drives but only a few of them will have an SD card reader. And in some cases, the USB port will also serve as a charging station for your smartphone.
- Auxiliary port (AUX): A simple way to connect your portable audio device directly into your radio.
- Near Field Communications (NFC): Technology similar to Bluetooth that allows you to stream music and share files but compared to the first one its transmission is slower and the range of communication is shorter.
- SiriusXM Satellite Radio: This is a subscription service offering over 150 channels, including weather, wind and wave forecasts and it’s available in the continental United States and its coastal regions as well as Southern Canada.
- Built-in microphone: A built-in mic grants you access to your phone through voice control, which then allows you to make phone calls without having to pick up your phone besides connecting you with your Siri or Alexa enabled devices.
With that being said, keep in mind that it’s important that you look for a radio system that not only suits your vessel but also your needs and pocket.

Frequently asked questions
Although it might seem intimidating, installing a marine stereo is actually pretty straightforward. First, you’ll need to figure out where to mount your stereo head unit. The important thing to remember here is you have to choose a mounting area that’s protected from the water, so you can either mount a marine stereo head unit on the dashboard area, or in the cabin. Some stereo systems are bracket-mounted, while others are flush-mounted; if you’re installing the latter, you’ll have to cut out an appropriate-sized hole on your mounting spot. Marine stereo systems are designed to be mounted horizontally, accounting for all kinds of boat movement. Once you’ve securely mounted your head unit, you then have to install speakers (pretty much in the same way you installed the head unit). Make sure your speakers are placed optimally for the best sound. After you’ve installed your head unit and speakers, you’ll then have to wire your stereo system to your boat’s power source. Now, if this all sounds too complicated, you always have the option of calling customer support for assistance.
This depends on what you’re looking for in a marine stereo system. If you want something that sounds premium and is compatible with all media, then you can’t go wrong with the Fusion MS-RA70. That said, if you want something compact, easy to install, affordable, and still delivers great sound, you can either get the JBL PRV-175, or the Boss Audio MGR350B.
As mentioned above, you’ll want to look at a few factors when buying a marine stereo. The main things you should be looking for is durability, and sound quality. You’ll want to make sure your marine stereo can withstand exposure to the elements, and you’ll want to get your money’s worth when it comes to audio quality. Additionally, if you’re not keen on spending hours on installation, you’ll also want to check if your marine stereo is easy to use and easy to install. Lastly, you’ll want to check if your marine stereo comes with additional features, as well as a range of preamp outputs.
No. Marine stereos come in different shapes and dimensions, some of which may not be suitable for your boat. While the US standard size is 2″ tall and 7″ wide, some marine stereos may be more compact, while others may measure 4″ by 7″.

Hi Jack. The BOSS MGR350B is a pretty good model. Easy to install, Bluetooth capable and with good sound, it’s also not too expensive. I must say though, that I do love that lapping sound of water. Sometimes it’s music that can ruin the sound of nature.
Hi Gear Geeks. Thank you for your reviewed.BOSS MGR350B is an ideal audio solution for any sailor. It can cancel that lapping water noise that spoils your favorite song while navigating. This is why BOSS happens to be one of the best marine audio brands.
There’s no problem keeping the connection between telephone and radio, for example. If you’re cruising far from the coast your signal for streaming might be dodgy. But otherwise any saved songs you have will play smoothly, loud and clear.
Isn’t there a problem using spotify when out on the water? I’m thinking the signal might not be so reliable.
