What to Consider When Buying a Marine Subwoofer

You might fancy yourself a boating expert, but marine audio systems are a completely different story. That said, you might find the market a little tough to navigate, especially with all the technical mumbo jumbo involved.

To make sure you’re buying the right marine subwoofer for your needs and preferences, take a look at these major considerations:

RMS Power Rating

RMS is an abbreviation for ‘root mean square’ which might not really make things any clearer than they already are. In essence, this is the mathematical measure of the best value of a waveform. For us lay people, that’s really just the power level of the subwoofer expressed in watts.

All technicalities aside, RMS simple refers to the amount of sustained power a subwoofer can handle. It’s always going to be lower than peak power (which we’ll get into a minute), and tells you the kind of performance you can expect out of your subwoofer most of the time. Although there might be some truth to the idea that higher RMS ratings deliver better bass performance, there are lots of other factors at play.

Peak Power Rating

If the the RMS power rating tells you the sustained performance of the subwoofer, peak power rating tells you the strongest and highest power level that a subwoofer can produce. Now, you can’t really expect it to operate at this level all the time, which is why the peak power rating only really manifests with a surge of energy.

Essentially, the peak power rating should give you confidence that the nuclear explosion that happens at the climax of your favorite movie is going to sound totally lit through your pontoon boat subwoofer system. But other than those high energy moments in audio, peak power doesn’t really mean much.

Impedance

This one can get pretty confusing, especially since it has a lot to do with your amplifier. Impedance, in simple terms, refers to the resistance of the coils in your subwoofer. This is measured in ohms. That means the lower the ohms on your subwoofer, the less resistance it will produce.

The reason why you might want to look into a low resistance subwoofer is because it makes it easier for an amplifier to supply power since it’s going to be met with lower resistance. Of course, problems might still arise if you pair your low impedance subwoofer with the wrong amplifier, so it pays to know how they work together.

Size

Size can affect the quality of sound that comes out of your subwoofer. But be warned - bigger doesn’t always mean better in the subwoofer category. A compact unit can deliver more directional sound which can be helpful in open air conditions like those on your boat. On average, marine subwoofers measure up to 10 inches in diameter, but smaller ones can deliver even better performance especially when you take time to consider placement.

Installation and Mounting

Now this one really depends on how invested you are in your subwoofer. Some of them will require an enclosure, which means you might have to buy one or punch a hole in one of your seats to give your subwoofer a place on deck. Then there are those that slip under a seat for added discretion. Others still come in their own enclosure, and require nothing more than mounting.

If you’ve really made a solid decision as to where your subwoofer should go, you could take it to the limit and drill in the mounting hardware. But if you want something a little more flexible, then a portable subwoofer that secures in place via a set of removable straps or hardware should be your best bet.

Waterproof and Marine-Grade

It would be wise to buy a subwoofer that’s specifically intended for marine use. Lots of those that are designed for cars and other applications can easily give in to the demanding conditions on a boat, leaving you with a broken subwoofer and an aching wallet.

Marine-grade subwoofers are typically designed to resist both moisture and UV damage. But there are others that take it the extra mile. Some stand up against salt and others are even constructed so as not to let in dirt and sand, which can be common for saltwater vessels. Read the fine print to make sure you’re buying a subwoofer that’s built for the conditions you typically boat in.

Drop the Bass

All the wind, waves, and open air can dampen the quality of your boat audio system. But that doesn’t mean you can’t do anything about it. The best subwoofer for a pontoon boat can help deliver the fullness of sound you’re craving for. Just make sure you consider the specifics and scout your options to make sure you’re getting a unit that really matches your standards.
