Selecting a Marine Stereo


By Tom Burden, Last updated 4/10/2019


The latest speakers from JL Audio feature Transflective™ LED lighting for an enhanced lighting experience aboard your boat.The ultra-bright RGB LEDs can be wired to display a single color or connected to an RBG controller (sold separately) so you can adjust the colors and ambiance as you please.

Single DIN, Double DIN, or Black Box?

Do you want a receiver that will fit into a standard DIN-sized opening? The US standard size is 2" tall and 7" wide, and most of our assortment fits that cutout, so your new stereo should fit without the need for a Sawzall to modify your dashboard. Some radios are built to the double DIN measurements of 4" tall and 7" wide. Others are oversized in the vertical dimension. Security features like detachable faceplates help protect your stereo from theft.

A Remote Server Controlled Through Your Multi-function Display

Using a remote server eliminates the need for a dedicated stereo head unit at the helm of your boat.  Marine audio servers use NMEA 2000 to commnicate with your multi-function display allowing you to control audio levels from the helm. This a great option for boats that have limited dash space or if you prefer less displays at the helm for a cleaner look.

Which Inputs and Data Sources?

Would you like to connect your iPhone, Android or iPod? Most marine stereos are bluetooth capable allowing you to wirelessly stream music from the library on your phone or iPod or from apps like Spotify or Pandora® while your phone is safe in a water tight compartment. USB and Auxilary ports are also included on most radios and allow you to plug your device in to the reciever directly.

Internal dock: You can choose a receiver with an internal docking station to keep your digital device safe and dry.

Advanced features: Many stereos can be controlled wirelessly from an included remote control or from an app on your phone allowing you to change the tunes from anywhere on the boat. Remote servers can be controlled through some NMEA 2000 compatible multi-function displays eliminating the need for a dedicated stereo head unit at the helm.

What Level of Waterproof Protection Do You Need?

Audio equipment in your car lives inside a waterproof, climate-controlled box. Your boat punishes audio components with spray, moisture, salt and UV radiation. The marine environment will kill an automotive-grade stereo in a few months or a single season under the best conditions, so saving money with a cheap car stereo is a mistake. What should you look for?

Marine stereos are rated either spray-resistant or waterproof. Look for CD slots that are sealed with rubber gaskets or hidden behind a water resistant faceplate. Faceplates can (in theory) withstand either spray or complete immersion, depending on the receiver. In reality, marine stereos often aren’t rated by clear, objective waterproofing standards, but are “marinized” for surviving in salt-water environments. Some receivers, especially those from poly-planar and Fusion, come with a submersible IP waterproof rating.


Wirelessly stream audio from virtually any Bluetooth device with available speaker/amplifier packages like Dual's MCP4165AL Bluetooth Amplifier and Illuminite Two-Speaker Package pictured here. Along with a 1200 watt amplifier, this package includes a waterproof/floating hand-held wireless remote control (not pictured) and two 6.5" x 300 watt marine-grade Illuminite Speakers that are back-lit to enhance the lighting in your cockpit.

Corrosion-resistant materials on good-quality marine units resist rust and salt water. Stereos include conformal coating of PCBs with a sealing coat of epoxy or urethane encapsulating circuit boards and processors. Plastic cases are UV-resistant. Speaker cones are polypropylene, not paper. Key metal components are often stainless steel. Wire is tin-plated and contacts are often gold-plated.

Do You Want a Satellite-ready Stereo?

SiriusXM Satellite Radio

SiriusXM Satellite Radio, siriusxm.com, provides 100 percent commercial-free digital satellite radio with a reception footprint (the area within satellite line-of-sight range) that covers the United States (including Alaska), Canada, and the upper third of Mexico.

Satellite radio is free from commercials and FCC restrictions, unlike AM and FM, so the variety of programming is superior. Just about any kind of music is available in every genre. The sound is digital quality (equivalent to an MP3 with varying amounts of signal compression, but not quite as spectacular as a CD) so you won’t hear static. Since the reception is the same across the continental U.S., you do not need to change your station presets if you travel from one place to another.

SiriusXM Satellite Weather Services

For boaters, SiriusXM has two types of subscription-based marine weather services. Sirius Marine Weather is available within the continental United States only. Navico and Raymarine make weather modules that receive four types of data.

XM WX Marine Weather from Garmin

Twenty data products for marine weather are available through customized marine subscription packages. Continuously updated graphical weather information, include these products and more: High-Resolution NEXRAD Radar, Lightning, Satellite Imagery, Buoy Data, Sea Surface Temperatures, FishBytes™ fish location data. See the Garmin GXM™ 53 Weather & Audio XM Satellite Receiver.
