best shallow mount subwoofer

This is my review of the best shallow mount subwoofers in 2021.

There’s nothing more satisfying than jamming out to your favorite tunes while on a long drive. However, many car audio systems simply don’t have the audio capacity to project sound with even or properly balanced levels.

Unfortunately, for us bass heads, we often miss out on the low-end sound we crave while playing music in the car.

Luckily, there are such things as shallow mount subwoofers. These compact devices can be rigged to your car’s audio system so that you can enjoy true bass while driving.

Below, we’ll go over exactly what you should look for in a shallow mount subwoofer so that you can find the right pick for you. We’ll also compare 5 of our favorite options below.

Things To Look For In A Shallow Mount Subwoofer

If you’re ready to pick up one of these speaker-enhancing subwoofers, there are a couple of factors you’ll definitely want to take into consideration. Be sure to evaluate your subwoofer of choice carefully by the following factors.


You’ll want to make sure that your subwoofer can handle your sound output. While peak power and RMS are both important factors, the RMS rating is the most important. This rating will tell you how much power the subwoofer can take in without malfunctioning.

Make sure that you speak with your car technician or audio expert beforehand to make sure you’re getting the right equipment for the job.


If you truly want heart-throbbing bass, you’re going to need to find a subwoofer with high sensitivity levels. This way, your subwoofer is much more reactive and ready to perform/emphasize those feel-good low notes regardless of what genre of music you’re playing.

However, there is also the option to buy an amplifier on top of the subwoofer— In this case, you can get by with a low sensitivity subwoofer.


This factor tells you how easy or hard it is for the subwoofer to convert the incoming signal into sound output. Therefore, the lower the impedance, the better the sound quality is going to be. You’ll notice less distortion and a stronger connection overall.

Voice Coils

When picking a subwoofer, you can go for a single coil or multiple coils. Multiple coils give you the flexibility to beef up your amplifier set up, producing a louder sound without having to invest in another subwoofer.


Don’t forget to consider where you want to install your subwoofer— Most people choose between mounting subwoofers underneath the seat or in the trunk. Keep in mind that the size of your subwoofer will affect this factor as well.


Shallow mount subwoofers are already made for fitting compactly in your car or space. However, there is still a good deal of variation when it comes to picking out the size of your shallow mount subwoofer. In general, there are 4 main sizes:

  • 8-inch: These small subwoofers fit in all cars with ease and are great for anyone who likes a bit more emphasis on low-end parts, but not overwhelmingly so. While they are compact, they’re definitely not for bass lovers who truly want to feel the pounding pulse in their chest while jamming out to their favorite songs.
  • 10-inch: These well-rounded subwoofers still fit in most cars with no trouble and provide a more enhanced bass experience than the smaller 8-inch model.
  • 12-inch: If you want to start feeling the bass not only in your ears, but also your head and chest, you’ll want to settle for 12-inch models and above to be safe.
  • 15-inch: These subwoofers are designed for large cargo trucks or anyone who wants an overwhelming amount of bass while cruising around town.
