Bazooka MBT1014

The Top Marine Subwoofer 

If you're looking for a marine subwoofer but don't have the time to do your own research and to compare prices, then go for the Bazooka MBT1014 Marine Subwoofer.

Superior build quality and UV + salt water-resistant design. For an absolute beast sound production, there is no better alternative than the Bazooka.

If you want to spend marvelously — spend your time on a boat. Nothing will beat enjoying a little extra punch from your marine stereo.

To have that, getting a top-notch subwoofer is the best solution.

The right marine subwoofer makes all the difference between having the greatest time of your life and passing some quiet, lonely time.

Subwoofers give the ultimate experience on a boat. They not only add an extra bass but also makes the speaker sound a lot better.

This is because a subwoofer takes the bass duty out from the speaker, and takes care of all the highs, mids, and deep lows. As a result, the speaker is able to deliver a clearer and crisper sound.

What to Look for Before Buying Marine Subwoofer?

By now, you have already read our top marine subwoofer reviews and probably deciding to buy one. But informed decision never hurts anybody. Before you go out and pick the best one among our picks, we suggest you understand on what basis we picked only these subwoofers out of hundred others.


Although this might seem obvious at the beginning, the size of a subwoofer often gets overlooked while buying. There are many different sizes to pick from, but the most common ones are 8”, 10”, or 12”. This measurement typically means the diameter of the cone inside.

Larger ones have deeper and louder frequency response while smaller subs produce tighter, richer sounding bass. So, depending on what type of sound you prefer, you have to pick the size.

But for larger cones, make sure you have enough space available. Also, keep in mind the mounting depth behind the sub to accommodate the magnet and cone.

Peak and RMS Power Ratings

The power of the subwoofer is of particular importance in terms of placing it on a boat. Because the sound will have to travel through the open air and so it needs more power to cut through it.

Furthermore, the first thing is that a best boat subwoofer needs is the ability to handle equal or more power than the speaker can provide. The power is represented in terms of watts. This power is measured in two different numbers: RMS and Peak Power.

RMS stands for Root Mean Square, which is a mathematical measure of a waveform’s best value. This is required for a recommended power rating.

The other figure is the Peak Power rating, which is the higher figure of the two. It basically means how loud the subwoofer will be able to perform before damaging itself.


This is a measure of electrical resistance. It is related to the power that the speaker is able to accept from the amplifier. Simply put, impedance means how easily electricity passes through the coils in the subwoofer. This is measured in ohms.

An ohm is the measurement of electrical resistance and is basically what impedance is. Lower impedance means a more powerful sound and vice versa. Most high-quality subs have lower impedance rating.

If the impedance is 4-ohm, it will extract more power than the one with more ohm. It should also be noted that this level of impedance should match the power of the amplifier. The amplifier could overheat if the impedance is too low compared to it.


Before going out to buy a subwoofer for your boat, installation is another factor that needs to be considered. Whenever you read marine subwoofer reviews, you’ll definitely come across sayings such as ‘easy installation.’ But if you are a novice, it becomes a bit tricky.


It is better to go for a plug and play subwoofer such as Bazooka if you don’t have hands-on knowledge of installation. But then again, you can also get a professional easily for this kind of job.

However, there is nothing to worry about if you just take proper measurements of the speaker before cutting any holes in your boat. Because you definitely don’t want to leave any lasting mark on it.

Marine Grade Material - Marinization

Most people will think of marine grade as simply water-resistant. But there is more to it since when you call a thing as Marine Grade, it is expected to conform to a higher standard than just water resistance.

On the water in the boat, salty air and fog can corrode any exposed metal, and UV rays from direct sunlight could damage mechanical devices. So before purchasing a sub for your boat, make sure it is fog, salt and UV certified also.


The subwoofer is placed into an enclosure in the majority of marine systems, which are basically made of wood. They come in different builds, sizes, and shapes with a sealed enclosure. The sealed enclosures are made for tighter sounding bass from the subs.

But the more popular builds are vented enclosures which give maximum output from a sub. They are made to produce deeper bass.


Proper wiring is crucial for installing a subwoofer for marine systems. We recommend using the best wiring possible to get optimal performance. The best wirings are made of 100% pure oxygen-free copper, and the size of it depends on the power needed for the system.

Frequently Asked Questions

Why do I need a marine subwoofer?

If you care about having the most wonderful time on the boat with the best sound, a subwoofer is a must for you. A marine subwoofer will be able to give you the best possible outcome in terms of perfect and loud thumping sound and bass.

Which subwoofer has the loudest sound?

Usually, the loudness of the subwoofer depends on the power it uses, size and impedance — the bigger the cone size, the louder the sound. To produce more sound, a sub uses more power but less impedance.

How much power do I need?

It depends on the subwoofer type. Although more power is better for subs, it needs to comply with that of the speaker. We recommend you choose an amplifier rated higher than the woofer’s maximum RMS power. This way, the sound quality is not distorted.

Do cone materials make any difference?

Just like speakers, subwoofers are made from Polypropylene cones. Besides, some sub cones are also made from treated paper or composites, which tends to be less durable. But because of its lightweight, it responds quicker than other materials.

What if the subwoofer gets wet? 

There is always a possibility of a subwoofer getting wet in the boat, just like the speaker. That is why we recommend marine grade systems throughout the boat to protect them from damages.

Final Words

We hope that our additional information from this marine subwoofer review article has helped you realize that finding a reliable product has become a lot easier. However, since your boat is surrounded by a harsh environment, do not forget to take care of the sub from time to time.
