Marine stereo systems are niche because they are designed to withstand the rough sea weather and pump up the sound to kill the nautical background noise. Each electrical component should be able to withstand the ravages of UV rays from the sun and high moisture and salt content in the air.

There are several popular brands like Clarion, Kenwood, Sony, and others who sell marine-rated audio equipment. For digging out the best stereo system from the shelves, you must know what you want first and know what is being offered. What is the difference between the term water resistance and waterproof? What rating should a component have to withstand the damage from sun and salt?

If a rating indicates that the audio component is water resistant, that does not mean you can submerge it. Water resistant gear can only resist water splashes or light rain. Waterproof equipment can be fully submerged for different time periods and at different depths of water. UV Resistance indicator on receiver faceplates, speaker cones, and grilles indicates that the components are protected against sun damage. Audio components require special protection from rusting and corrosion. Circuit boards, cable connections, chassis, and other components are protected against corrosion by coating or plating them with anti-corrosive substances. In addition to individually protecting audio gear against salt, sun, and water, you can install a universal cover that flips down to enclose the receiver and flips open to give you access to its controls. Alternatively, you can place the receiver in a watertight chamber to prevent shorting. If you don’t want to expose the receiver at all, then a waterproof, wired remote control can be used to operate the receiver. The universal cover also protects non-marine components from damages.

Irrespective of whether the audio equipment is meant for terrestrial use or marine operation, good specifications simply mean good quality. The stereo system should be capable of silencing the uproar of the engine and other background noises to grab your attention. If soothing music has to reach your ears in the open sea cutting across the many disturbing factors, you must select the audio equipment with the best specs: high signal to noise ratio, wide range of frequency response, and high RMS power. High power translates into clear and loud music. Most branded marine receivers have a built-in four-way amplifier. You can consider adding an external amplifier to your system in order to boost overall performance. For reading FM signals in the deep sea, lower FM sensitivity is better.

Always plan big when it comes to prepping up your music system and select a design that is flexible. With the wide array of audio-visual entertainment options available today, including advanced satellite radio systems and high-octane handheld devices, you are pampered for choice. You can iteratively develop a bigger audio setup if you assemble a stereo system where the receiver has the provision for auxiliary input and many sets of preamp outputs. The auxiliary input can be used to add an audio source later while preamp outputs can be used to connect and control externals amps and subs. Equipped with your state-of-the-art stereo and satellite radio and antenna, nothing can stop you from catching the audio signals up to 200 miles off shore.

It’s not easy to set up your stereo system in a boat unless if you are replacing existing components. You may have to identify different mount locations to put together all the components. For instance, mounting receivers and speakers may require cutting panels or connecting components with long winding cables. Amps and subs may have to be housed under the seats or bow or on the wakeboard tower. Side panels or dashboard is roomy enough to host midrange speakers and tweeters. For grounding components though, you may need to consult your manufacturer.
