What are the Best Marine Subwoofers?

While cruising out on the ocean or hometown lake, there’s nothing better than enjoying your favorite album or artist playing in your boat.

A marine sub-woofer can enhance your sound experience ten-fold, including amplifying the bass tones in whatever music you put into listening.

Relieving the bass duty will result in better sound from your speakers. Instead of pumping out the lows, mediums, and highs, your other marine speakers can deliver the crisper, clearer high and mid-range sound while your subwoofer takes care of the deep lows.

An angler has an added treat when they install a subwoofer. Subwoofers amplify the bass of their music, and they will be able to attract fish to them because fish can be attracted to low-frequency sounds.

Boat Subwoofers Buying Guide

Here are some of the specifications that you need to investigate if you are interested in buying a subwoofer. They will assist you in making the right choice before you invest in an ideal product:

  • Power ratings
What are the Best Marine Subwoofers

The power of a subwoofer product will be of particular importance in placing a speaker in a boat. It needs to be powerful enough to be able to cut through the open air so that you can enjoy the music.

The watt power should be measured with two different numbers as you will see a lower amount and a higher figure. RMS, which means the root mean square of the speaker, will be represented by the lower number.

The measurement is the best value of the waveform, which is essential for the recommended power rating.  The peak power rating will be the other figure, and it will always be the higher figure between the two.

It shows how loud it will be before the device can no longer handle it. There will be a higher amount of power needed because of more space in a larger boat which the sound would need to carry.

You need to know more about the power rating to get the most out of your subwoofer. When on a boat, a stereo unit and amplifier will be able to cope with an increase in sound volume.

  • Marine-grade materials

Marine-grade materials conform to a higher standard than any other type of subwoofer. It has to be water-resistant to deal with the inevitable splashesNon-resistant water subwoofers will cause huge problems, and it applies equally to speakers, battery, and stereo.

The UV lights can damage a subwoofer that is direct to the sunlight. It is vital to guard against these potential dangers, and the best marine subwoofers handle these types of hazards.

  • Impedance

It is a measure of electrical resistance and the related amount of power that your speaker will accept from your amplifier. A speaker with less impedance extracts more energy from an amp than one with a high one.  The amplifier impedance level should match that of a subwoofer so as to avoid overheating of amplifier or damage of the output tube and transmitter.

  • Installation

Make sure the subwoofer fits in with your existing marine speakers. You have three options during installation; you either plugin or play the model that can easily be connected, you can do the wiring yourself, or hire a professional.
