Buying Guide — Choosing Your Own Marine Subwoofer

Best Marine Subwoofer ReviewsWe’ve given you the top ten marine subwoofers that will go well with your boat’s sound system. To help you make your purchase, here’s a detailed buying guide that will discuss the important features of marine subwoofers.

Power Ratings

A subwoofer’s power rating is a good indicator of how loud the sound coming out of the subwoofers will be. And if you’re using it on a boat out in the open, the sound should have enough power to reverberate throughout the boat. Otherwise, a low power subwoofer might not let you feel the bass enough to enjoy it.

To measure the subwoofer’s watt power, you have to look at two key numbers that are used to indicate the device’s power. One number is lower and that indicates the RMS. This helps you determine the ideal power rating for your subwoofer’s best waveform value. The other number is higher, and that’s the peak rating for the power. It indicates how loud your subwoofer when it reaches the maximum level it can pump out. If your boat is quite large, then you should ideally get a subwoofer with a high peak rating so the audio coming out has a better chance of covering your entire boat.

It’s also ideal to get an amplifier and stereo unit for your boat too. They will help your sound system handle your subwoofer, particularly when you start turning its volume up.


The impedance of your subwoofer is another important indicator to take note of. Impedance measures the electrical resistance of your subwoofer and is connected to how much power your amplifier can provide your speaker.

A good rule of thumb is to get subwoofers with lower impedance levels. For example, a speaker with 8 ohms won’t get as much power from an amplifier compared to a speaker with 4 ohms. So if the sound volume is your concern, lower impedance speakers will be better.

You will have to ensure that your amplifier’s impedance matches your subwoofer.  If your amplifier has a lower impedance level than your subwoofer, then it might overheat. If it’s the other way around, then the transmitter and output tube can sustain damage. So be sure to check the impedance levels before purchasing.


Check your boat and the subwoofers to see how you plan to install it in the available space. You don’t want to get a subwoofer that seems too large or too small for your boat. It should also be compatible with the speakers you already have.

When mounting it, find a place where it correctly fits in. It’s also necessary sometimes to have holes where the wiring and cables can pass through. Be prepared to cut out some holes or space to accommodate the subwoofer. In this case, you need to be very careful since you don’t want to make a mistake with the fitting process. If you’re uncertain about doing it yourself, then just have someone qualified to do it instead.

There are also many ways you can connect it to your sound system. If you’re confident enough, you can just set up the wiring on your own. If not, perhaps it’s better to call an expert to do the installation. The most convenient option would be to just get a plug-and-play subwoofer model.

Marine-Grade Build

A product labeled marine-grade means that it’s build quality and construction is specifically designed for marine use. It’s essential that your subwoofers have water-resistance since there’s bound to be some water getting onto it with all the splashing and raining out at sea. If the subwoofer isn’t properly built to be water-resistant, there’s a chance that water could get onto the internal components, which is a surefire way to get it damaged.

Aside from water protection, your subwoofers should also be able to withstand other marine elements like salt and UV rays. Salt could introduce corrosion and UV rays could fry the internal parts.

That’s why you should never settle for a subwoofer with poor build quality and resistance. If you want it to have top durability and longevity, then it must offer the necessary protection against environmental hazards.
