Using a Car Stereo in Your Boat?

The car radio head unit has been tried and tested millions of times, so why is it not advised to use them in your boat? The idea of using a car radio system in the boat can work but its extremely important that you use a protective cover. This plastic cover over the head of the radio will give the head unit some waterproof cover.

However, boats will get wet and not all stereo systems will be located within a cabin. Examples of this may be speedboats, ribs, tenders and more. Marine stereos are designed to be water proof and this is why they cost slightly more than car stereos. The waterproofing will prevent electrical components becoming shorted out as well as other benefits.

For the sake of a small amount extra, investing into a marine head unit that has been designed for the marine environment is highly recommended. Marine stereos may also be classed under motorcycle stereos as they too are water resistant due to obvious reasons.

Benefits of Using a Marine Stereo

  1. UV Protection from the Sun
  2. Water Resistance
  3. Anti Corrosion Protection
  4. High Quality Material (Compared to a Cars Stereo)
  5. Inclusion of Marine Weather Radio

Of course a car stereo may be cheaper, but for the sake of a few extra dollars, the marine stereo alternative is definitely worth the extra money. The waterproofing and the extra sealed components of the stereo system will reduce water entering the electrical area of the boat.

Desirable Features

Many manufacturers will litter the description of marine stereos with technical jargon and you may just skim through it. However, you will want to ensure that the head unit that you buy is full with excellent functionality.

Bluetooth connectivity is a must with the smartphone craze with the likes of Spotify and Apple Music. Not only does it allow for the obvious music streaming but it also means there is less chance of water entering the stereo.

For example, if water was to come onboard, if you have a CD slot or AUX/USB port, water may enter the head unit. The CD player is the worst culprit and many marine stereos will completely get rid of the CD functionality to improve its qualities as a marine head unit.

Ensuring that the stereo also has a range of outputs is also critical for those planning on adding a range of marine speakers. You will want to pay particular attention to the number of channels, the wattage and whether it has a built-in amplifier (although you can add a separate marine amplifier).


Choosing a marine head unit for your boat that has excellent waterproof properties, is easy to use and has the output for additional speakers is a hard task. You have a choice of styles with many offering Bluetooth connectivity, which is a huge bonus because you are able to connect your smartphone form music streaming and even handsfree calling.

In terms of the single din style, the Kenwood is the winner. The styling suits a boat decking more than the boldness of the black JVC stereo. All the power output channels and audio inputs are all available, making it a very capable and reasonable priced stereo.

The best marine stereo overall has to be the INF-PRV250 by Infinity Audio. Like with the single din radio by Kenwood, it has excellent power and channels for extra speakers. However, its not styled like a car radio, but more for a boat. This for me makes it the winner as this will look much better within a boating environment.
