Best Shallow Mount Subwoofer For Heavy Bass [2023 Reviews]

A shallow mount subwoofer is built to reproduce the deep bass possible for tight spaces. Only because you have small space for speaker enclosures it does not indicate you have to give up the hope of producing amazing sound quality.

Thanks to their small subwoofer size and low installing profile, expensive shallow mount subwoofers could be positioned in a broad spectrum of applications and cars where traditional subwoofers won’t typically fit. Thus, if your vehicle has a factory-installed subwoofer, chances are it is a shallow mount sub.

Irrespective of their compact layout, these subwoofers could include a deep bass foundation. Nonetheless, don’t expect those subs to turn your entire trip into a moving electrical storm of loud bass.

Thus, what precisely are the most effective slim subwoofers on the market today? Lucky for you, this article put together the top ten recommendations for the best shallow mount subwoofers available to achieve a smooth listening experience.

What to Look for in Best Shallow Mount Subwoofer?

When you want to buy a subwoofer for your car, what is the first thing that you think about? And here we go again. Nowadays, with social media and the internet, everyone has an opinion about everything.

Getting the best shallow subwoofer should not be a difficult endeavor. Below are the important things you need to keep in mind when buying your subwoofer.

RMS Power rating

How much power can the sub-woof handle before it blows or caves out? That’s the definition of peak power. The higher the wattage, the more it can handle. Thus, we recommend going for a peak power of 6 to 800 watts.

You’ve probably also seen the term RMS throughout this guide. RMS stands for root mean square—the power a subwoofer can constantly handle. For subwoofers, 50 watts RMS to 250 RMS power is a great start, but it is common to have higher RMS power as well.

Nonetheless, that’s greatly associated with the sub’s size too. Thus, a smaller 8-inch option that has a peak power of 300 does not indicate it is a low-end product. Other people opt for the installation of their subwoofers to factory stereos.


Frequency refers to the range of frequencies the subwoofer can create. Simply put, the broader the frequency range, the more versatile the sub is.


The sensitivity refers to how well the sub could keep up and still pump out the music. The sub sensitivity’s stats are measured by how loud it is along with one watt of power.

Rapid Heat Dissipation

Technological products and devices like the shallow mount sub heat up during extended use. The same applies to your TV, computer, phone, and others. That could affect the device’s performance after some time.

A great subwoofer would have an adequate inbuilt airflow management system to regulate the temperature and keep the subwoofer in a cool state. They also come equipped with an advanced motor structure to ensure the best performance for many years.

Voice Coil

There are two types of voice coils: single and dual voice coils. Each type has a different magnet and wire. A single voice coil has just one magnet and one coil of wire, while dual voice coils have two magnets and two coils of wire.

The size of the voice coil varies from one subwoofer to another. Getting an anodized aluminum voice coil is a great way to improve the overall quality of your subwoofer. They help keep the subwoofer cool, and they also last for a long time.

Main Shallow Mount Car Subwoofer Specs

When it comes to which size of shallow mount subwoofer you should get, it is important that you pay attention to the specs. You will see many subwoofers having similar or smaller measurements compared to the others. However, they come with different mounting depths.

Shallow subwoofer measurements are usually written in inches, or at least there is a marking on the box. The important measurements are the mounting depth and the outer diameter of the woofer. Here are some other important specifications to know:


There’s no single subwoofer size for everybody. That seems like a no-brainer as you need to get one that accommodates perfectly. These subwoofers come in various sizes.

The bigger the shallow mount sub, the thicker it gets. So, make sure you don’t look into the subwoofer size but the shallow mounting depth too.

Shallow mount design

Ensure the measurement is compatible with the car space it will occupy. It will cramp the space and the style as well. Go for mounts at least 3 to 3.5 inches. Anything more than that will limit much space.

Cone quality

Plus, these subwoofers come with a variety of different cone materials, but one of the most durable and long-lasting is anodized aluminum cones.

It is challenging to understand how dependable something is by simply reading the specifications and descriptions. Thus, the opinions of the real users will come in useful. You get a glimpse of the performance when in real use. Look for a subwoofer with a guarantee or warranty, as it’s the smartest thing to do.

Do you want to choose a separate shallow mount or amp setup?

Then be extra cautious on buying an amp that fits tight spaces and has the proper power levels for the small woofer.

On the other hand, the variations in the quality of accessible shallow mount subwoofers are as a side as the horizon. When searching for one that will last, always consider the price, the quality of materials, and the brand’s reputation.
