How Does a Marine Audio System Work?

Installation

Marine audio system
Marine audio installation differs from other vehicle audio installations because there is not only one location in a boat that you can install it. For cars, you would always place the audio system in the dashboard. However, in boats there are space and power limitations you have to work with during the installation process. If you are installing one for the first time, you would need to cut out some paneling and run electrical wires to install your marine audio system. Since marine vehicles are bigger in size than most cars, you may need to run wires at different areas for additional speakers so that you can hear the sound from different areas of the boat. You must take into consideration to place the audio system where there is least sun or heat exposure, as well as exposure to moisture and water.

Most marine audio receivers utilize a standard single DIN (Euro DIN) size connected to a 12-volt marine battery. This can slide into a metal or plastic sleeve, which attaches to the front of the mounting rack. You can run it in continuous power, especially if you use your boat often. Doing so maintains its internal memory, like the clock and preset radio stations. If you do not, you may drain your battery if it is in continuous mode even with very little power requirement.

It is important to ground the electrical components properly. Find your boat's grounding plate that you can use in order to accomplish this task. If you are unsure of the location, you can call your boat manufacturer to ask where you can find it.

Take into account the open environment when installing marine audio systems. The speakers should be able to produce higher music volume that has lower levels of distortions, as well as, be able to handle more power input. They should also be resistant to the damaging effects of the marine environment.

Ensure that the amplifiers receive more power to get better sound and louder volume, which is important in an open air environment. This will drown the noise coming from the boat's motor, the noise coming from the wind and water waves. Installing the amplifier with a thick power wire directly to the boat's battery and running the audio cables to the unit's preamplifier outputs. You may also need to connect the speaker wires to the amplifiers.

To get radio waves to listen to AM/FM radios, there are radio and satellite receivers included into the marine audio systems. The satellite receiver can provide uninterrupted signals from satellites above for 24 hours of commercial-free entertainment. Radios through airwaves have more interruptions and may need an extra outside antenna to make the signals better.
