Best Marine Subwoofer Buying Guide

Peak Power Output

The higher number that is advertised is the peak power output.
The greatest amount of power that a subwoofer or speaker can handle is expressed in Watts.
But don’t let it deceive you.
Although it’s a significant number, a speaker can only sometimes reach that power output, and it won’t be a steady power output.
When a section of a song becomes louder than the rest, this number comes into play.

Yet, it’s a crucial figure to monitor.
The ideal subwoofer should have a peak power output that is equal to or more than the maximum power output of your amplifier.
Your subwoofer could be damaged if an amplifier provides more power than it can handle.

Power Output

The RMS power output of a subwoofer or speaker is a much more relevant indicator of a speaker’s actual capabilities.
Root Mean Square is referred to as RMS.
In layman’s words, let’s call that the average production.
This number represents the maximum power output that a speaker is capable of supporting.
Almost always, this number is considerably lower than the peak power output figure.
Despite having a 600 W peak power rating, a subwoofer might only have a 300 W RMS.

When looking for a marine subwoofer, this is the most crucial statistic to consider.
Have in mind, however, that manufacturers frequently interpret this measurement differently, and the formula used by one brand to determine the RMS of their product may not be the same as the one used by another brand.


The impedance rating of a subwoofer is a gauge of its electrical resistance.
Although it seems difficult, it’s really not.
However, it’s not the most crucial function available.
It’s still important to be aware of though!
Ohms are used to measure impedance.
The unit of electrical resistance is the ohm.
Similar to a huge electrical resistor, a speaker (or in this case, a subwoofer) can tolerate more amplifying power the lower its ohmic value.
Simply put, low ohms are preferable to high ohms.

Thankfully, all of the aforementioned models are among the best marine subwoofers available and have low impedance.
You should ideally search for something with a resistance of 4 ohms or less.
Just so you know, Ohms can also be denoted by the symbol.


Any subwoofer, regardless of impedance or output power, is only functional if it can be mounted.
Although installing speakers isn’t difficult, you should limit your search to models that just require simple wiring and straightforward mounting if you’re uncomfortable with the concept of installation.

Certain maritime subwoofers are speakers that, in order to produce the best bass, must be positioned in a box or enclosure.
Some are free-standing structures that rest on the deck.
There are some that may be easily placed into the bodywork of your boat.
Before clicking the buy button, whatever the case, be sure to read up on how they should be installed and read reviews from previous customers.


Before purchasing a subwoofer, you should think about its physical size in a manner similar to how it will be installed.
Not only the size of the box it comes in, however that is something that should be taken into account given that there is never enough space on a boat.
We actually mean the diameter of the speaker itself.
The most typical subwoofer size is 10 inches, however this isn’t always the case, and bigger doesn’t always equate to better or louder.


Last but not least—and perhaps most crucially—you should see how well a marine subwoofer can actually endure marine-like environments.
There are numerous products sold under the marine brand, but not all of them are reliable.

More features than only water resistance can be found in the top marine subwoofer models.
Also, they will have UV-resistant coatings that prevent the sun’s rays from destroying their constituent parts.
Important electrics should be covered in protective coatings to shield them from corrosion caused by salt and water spray.
To prevent sand and dust from entering inside your speaker and causing problems, seals and gaskets should be placed.

Make sure the product you buy has actually been created for a life on the sea.
If it appears to lack the necessary credentials, get rid of it and go on.
Spending money on something that won’t work is pointless.
