If you’re on a tight-budget and looking for an affordable marine stereo that doesn’t cost an arm and a leg, then Pyle PLMRB29B is a decent option to consider. It’s one of the cheapest marine stereos that you can buy.

This unit is designed to be a decent replacement to factory receivers. It only has a few basic features such as Bluetooth connectivity, USB port, SD memory card reader, aux input, along with rear panel RCA connectors.

What makes marine stereos different?

Unlike car audio components — which are designed to be installed in an enclosed vehicle where they’ll be safe from outdoors elements — marine audio components have to be able to withstand an open climate. The water, extreme temperatures, moisture, salt and sun that make sailing and boating so much fun for you can wreak havoc in your boat’s electrical components. Therefore, if you audio components aren’t made for this sort of abuse, they won’t last too long.

Marine audio manufacturers know this. That’s the reason why they put their components through hundreds— if not thousands — of hours of extensive pre-production testing to make sure they’re durable enough to stand up to harsh marine elements.

These pre-production tests include but not limited to :

  • UV test chambers to simulate years of direct sun exposure.
  • Special “salt fog” chambers to simulate years of exposure to harsh salt water environments.
  • Water splashes to test every seal and ensure that every button, knob, and port is moisture-proof.

With that said, here are the three key things to consider when you’re looking for a marine-grade audio equipment, be it speakers, receiver, amplifier or subwoofer.

  • Water resistance: Any marine equipment that is water resistant can handle water splashes and light rain, but isn’t built to handle submersion. Only water-proof gear can be fully submerged without getting damaged.


  • UV resistance: Being able to withstand sun damage (ultraviolet rays) is one of the most important feature to look for on receiver faceplates, speaker cones and remote controls.


  • Anti-corrosion protection: salt water and moisture are known to substantially decrease the life expectancy of electronic components. Thereby, look for components that are designed to resist rust and corrosion. These components are usually featured with coated circuit boards, plated connections, and rust-resistant chassis components.

How to Choose the Best Marine Radio

In order to choose a good marine receiver, here are a few things you should take into consideration:

The right specs

Just like car audio components, better specs means better sound quality. When it comes to marine receivers, look for a high CD signal-to-noise ratio, high RMS power output, at least one USB port and Aux input. And if radio is your thing, check the FM sensitivity spec — the lower, the better.


Nowadays, aftermarket receivers are incorporated with a ton of bells and whistles you need to stay entertained at the dock and on the water. Today’s aftermarket marine receivers are every bit as powerful and feature-packed as their automotive cousins.

They have Bluetooth connectivity for hands-free calling and audio streaming, HD radio, satellite radio, Siri Eyes Free, Pandora® Internet radio control, and various other sonic goodies. It basically boils down to this simple fact: the more features you want, the more money you’ll have to shell out.

High Power Output

Because no boat cockpit/deck isn’t acoustically perfect, and since you’ll be listening to your music out in the open, high power output is a must for crystal clear sound. Most marine receivers are incorporated with built-in 4-way amps, but if you’re a serious audiophile who loves it loud, you might want to consider adding an external marine amp to your system.

Expandability options

If you’re planing to build a strong audio system, consider a marine receiver with multiple sets of preamp outputs. That will make it a lot easier to connect and control external amps and subs as you build your ultimate marine audio system. If you like listening to Satellite radio, consider a receiver that’s SiriusXM satellite radio ready.

Types of Marine Receivers

Marine receivers come in a variety of shapes, sizes, and configurations. Choosing the right one for your boat will depend on the space you have for the receiver, the features you need, the available audio sources, and the type of the receiver. Speaking of types, marine stereos come in 5 categories.

Single-DIN marine receivers

Single DIN marine stereos look and perform like standard single din car stereos. They’re the most popular and versatile marine receivers on the market.

Unlike their auto counterparts, marine-grade single DIN receivers are designed to withstand harsh marine environment. To stand up to moisture, sunlight, and salt, these receivers are featured with conformal-coated circuit boards, water-resistant faceplates, and special covers for CD openings and/or USB and AUX port.

Single DIN stereos will fit neatly into a wide variety of boats, but it’s mandatory that you measure the depth of the cavity you’re working with before buying your receiver.

If the cavity of the stereo isn’t deep enough to accommodate a regular single DIN stereo, then you might want to consider a digital media receiver. Since there’s no built-in CD player, the digital media receiver’s chassis doesn’t need to be nearly as deep, so it’ll fit into tighter spots and smaller boats.

Gauge-mount marine receivers

Because they have no built-in CD drive, gauge-mount digital media receivers tend to be quite compact and versatile, which makes them ideal for smaller boats.

These receivers are designed to fit into standard-size (3″) openings. If you boat has no dash opening already, the design of these receivers makes it easy to create one.

Like all marine-grade receivers, they’re coated and sealed in all the right places, so they’ll give you great performance for many years to come.

Oversized DIN receivers

Oversized” DIN receivers feature larger faceplate which allows for more controls and bigger displays. Despite being relatively large, these receivers can still fit into a standard 2″ tall opening.

These receivers are a bit tricky to install as they require a little more mounting space for the faceplate, so bear in mind to not only take the depth in mind, but also the area around the cavity. Measure twice and cut once, by the way.

“Black box” marine receivers

This type of receivers are designed to be installed out of sight. They perform just like a regular and are feature with all the functionality and connectivity you’d ever want from a marine stereo.

These receivers come in two pieces, the box and the control unit. The former is not nearly as water-resistant as marine grade receivers specifically designed for outdoor duty, so mount it somewhere where it won’t be affected by the elements. The latter, however, can be mounted just about anywhere in the boat’s cockpit.

Mounting each of these will depend on the layout of your boat. That’s part of the versatility of the concept.

Square receivers

Like their oversized-DIN cousins, these close-to-square receivers feature a relatively large faceplate and can fit into small panels. And since these digital media receivers don’t have come with a CD player inside, they usually don’t require much mounting depth.
