Best shallow mount subwoofers – Buying Guide

When it comes to choosing the best shallow-mount subwoofers, there are several factors to consider to ensure you get the right one for your needs. Shallow-mount subwoofers are designed to fit in tight spaces, making them ideal for vehicles with limited mounting depth. Here’s a buying guide to help you make an informed decision:

Size and Mounting Depth:

When choosing a shallow mount subwoofer, consider the available space in your vehicle. Opt for a size that fits well and a mounting depth that allows for easy installation without interfering with other car components.

Power Handling:

Select a subwoofer with power handling that matches or slightly exceeds your amplifier’s output. This ensures that the subwoofer can handle the power without distortion or damage.


Higher sensitivity is generally better, as it means the subwoofer can produce louder sound with less power input. Look for a sensitivity rating above 85dB for efficient performance.

Frequency Response:

A good frequency response typically spans from 20Hz to 200Hz or more. This range allows the subwoofer to produce deep and rumbling bass as well as handle higher bass frequencies for a well-rounded audio experience.

Cone Material:

Subwoofers with cone materials like polypropylene or Kevlar tend to offer a good balance between rigidity and flexibility, resulting in clear and accurate bass reproduction.

Voice Coil Type:

Opt for dual voice coil subwoofers if you want more wiring flexibility, as they allow for different impedance configurations and can be connected to multi-channel amplifiers more efficiently.


Match the subwoofer’s impedance with your amplifier’s requirements to ensure it receives the appropriate power and operates efficiently. Common options are 2-ohm or 4-ohm.

Enclosure Type:

The choice between a sealed or ported enclosure depends on your preference for bass characteristics. Sealed enclosures provide tight and accurate bass, while ported enclosures offer louder and deeper bass.

Brand Reputation:

Trust established and reputable brands known for their quality and reliable performance. Research customer reviews and expert opinions to gauge the brand’s reputation.

Customer Reviews:

Consider user feedback to gain insights into real-world experiences with the subwoofer you’re interested in. Look for consistent positive reviews regarding sound quality, durability, and overall satisfaction.

Best shallow mount subwoofers – FAQs

Do shallow-mount subwoofers sound good?

Shallow-mount subwoofers can indeed sound impressive, despite their compact design. While they may not match the sheer power and depth of larger, traditional subwoofers, their specialized construction enables them to fit into tight spaces, making them ideal for smaller vehicles or limited installation areas.

Shallow mounts utilize clever engineering to deliver tight and punchy bass, adding depth to your audio experience without sacrificing too much space.

While audiophiles seeking the utmost in low-frequency performance might opt for larger options, for most enthusiasts, shallow-mount subwoofers offer a fantastic compromise between size and sound quality, enhancing the overall audio system without overwhelming the car’s interior.

What are the benefits of a slim car subwoofer?

A slim car subwoofer offers several benefits, primarily due to its compact design.

1: It takes up less space in the car, allowing for easier installation and saving valuable cargo room.

2: It provides enhanced bass performance without compromising on audio quality, making it ideal for vehicles with limited space for larger subwoofers. Additionally, a slim subwoofer is often more lightweight, reducing the overall load on the vehicle.

3: It can be discreetly placed in various locations, maintaining the aesthetics of the car’s interior while still delivering impressive low-frequency sound, ensuring an enjoyable audio experience for the driver and passengers.

How do I install a slim car subwoofer?

Installing a slim car subwoofer is doable for most people who like to do things themselves. You’ll need some basic tools and a bit of know-how. Here’s what you can do:

Decide where you want to put the subwoofer. It could be in the trunk or behind one of the seats.

Next, get or build a special box to fit the subwoofer. The box is important because it affects how the subwoofer sounds. You can choose between a sealed box or a vented one, depending on what kind of sound you want.

By following these steps, you’ll be on your way to having a great sound system in your car!

What is the difference between a slim car subwoofer and a regular car subwoofer?

Regular car subwoofers are larger and have a typical design, while slim subwoofers are smaller and specially made to fit in cars with less space or for a sleeker look. Slim subwoofers have different designs, including the frame, cone, surround, spider, and motor. Even though modern slim subwoofers are quite powerful, there is still a slight performance difference compared to regular subwoofers.

What Size Shallow Mount Subwoofer Is Best?

Imagine subwoofers as speakers that make the thumping bass sounds in your car’s sound system. The bigger the subwoofer’s surface area (the part that moves to produce sound), the more powerful and detailed the bass will be.

But not all cars have enough space for large subwoofers. In small vehicles, an 8-inch subwoofer is the best compact choice. If you have a bigger car with more room, you can go for a 12-inch or even a 15-inch subwoofer to get even better bass.

In simple terms, bigger subwoofers give richer bass, but smaller ones are more practical for tiny cars, while bigger cars can handle larger subwoofers for even more impressive bass sounds.

Should I get 2 or 4-ohm subwoofers?

To achieve a louder and more powerful sound, opt for a 2 Ohm subwoofer, while a 4 Ohm subwoofer ensures clearer and deeper bass without distortion. However, for those seeking energy efficiency and cost savings, the 4 Ohm models are the ideal choice, as they consume less electricity.

So, consider your priorities: if it’s volume and intensity, go for 2 Ohms; if it’s clarity and efficiency, opt for 4 Ohms. Ultimately, both options offer distinct advantages, catering to diverse preferences and requirements in creating an immersive and enjoyable audio experience.


When it comes to finding the best shallow-mount subwoofers, there are several top-notch options that cater to your space-saving needs without compromising audio performance. These compact powerhouses pack a punch, enhancing your car audio experience with deep bass and rich sound. With their slim designs, they easily fit into tight spaces, making them ideal for smaller vehicles or those seeking a seamless installation.
