If you want to get the best bass out of your music during your drive, upgrading the stock stereo speakers is a must. Yet, not every subwoofer has to be big and bulky to give you great lower tones. Shallow-mount subwoofers are smaller and able to fit more snugly in places while still giving you a great low thump. Here are the best shallow-mount subwoofers we found to grace your ears with a smooth, low bass.

    Best Shallow-Mount Subwoofer Reviews & Recommendations 2020

    Best Overal

    This small 8-inch shallow-mount subwoofer still packs quite the punch. Don’t let its compact size fool you, it has a peak power of 300 watts and RMS of 150 watts. It works as a great replacement for a car’s factory speaker system.


    A great feature of this shallow subwoofer is that even though it’s on the smaller side of subs, it’s able to compete with some of the more beefier and larger speakers with the added bonus of being mounted more places in your car. It has an immense power range and produces loud, clean sound with great low tones that shake throughout the car.


    While it may be able to fit in more areas in your car, mounting it can be an issue. You may need to drill new holes in the enclosure to properly hold it in place. While we found it did bring out the lower tones of songs, it may need a more powerful amplifier to really make them quake.

    Best Value

    Whether you are looking for a recreational speaker or a compact unit to upgrade your car audio set-up, the JBL Club WS1200 packs it all in terms of great power and design technology. It’s a component subwoofer with a peak power handling of 1000 watts and continuous RMS power of 250 watts. Its sensitivity is set at 92 decibels and the frequency response ranges from 27 to 275 hertz. 


    As for the design, the speaker has a rugged look with the woofer cone being made of polypropylene and has a butyl rubber surround. The speaker is designed with a Selectable Smart Impedance switch that lets you change the impedance from two to four ohms. You, therefore, wouldn’t have to buy a new subwoofer if you needed to include an amplifier in your car audio system. 


    However, you may notice a few drawbacks with the speaker. It may take some time to break it in before you get the deep bass that it's capable of producing. It has a high power output and may drain your car battery faster than your factory speakers. Moreover, the speaker doesn’t come with mounting grilles to protect the woofer cone from mechanical damage.

    Honorable Mention

    This shallow-mount subwoofer varies in size and price, which is great for anyone searching to replace their standard stereo speakers. It starts out at 8 inches and has 800 watts of peak power and 400 RMS power. Compare that to the largest size of 12 inches, also with 800 watts of peak power and an extra 100 RMS, and you’ve got a great deal.


    Mounting this shallow-mount speaker depends on the size you get. The 8-inch speaker has a mounting depth of nearly 4 inches, making it easier to mount in small spaces, while the 12-inch sub is just shy of 5 inches. Another great benefit is no matter what size of speaker, you can get them with either dual 2-Ohm voice coils or 4-Ohm voice coils. Either way, this speaker produces a crisp and clean sound, splitting the low and high tones equally throughout the car.


    However, even though it states the peak power and RMS are on the higher end, the speaker may not be able to handle the optimum range for long, especially if running off the car’s factory stereo and amp. This could be solved by upgrading the amplifier to make sure the system operates at full capacity for a longer amount of time.

    Benefits of Shallow-Mount Subwoofer

    • Boost your audio system’s bass. The most powerful subwoofers will tremendously enhance your music when compared to factory car speakers. They provide a deeper bass undertone than the standard speakers can put out. A shallow-mounted subwoofer will have more power and impact, regardless of the environment.
    • Protect your factory speakers. If you like a lot of bass, you can potentially damage your car’s factory speakers which aren't designed to tolerate large levels of vibration. They aren’t fitted to handle a large amount of bass. Subwoofers are specifically designed to enhance the lower frequencies throughout your car. OEM speakers may tear or crack because they're typically made of cheaper material.
    • Provide a smooth output of sound. Subwoofers help control where the lower sounding frequencies go in your car. A subwoofer will channel the bass notes more powerfully and with a cleaner sound, leaving your speakers to focus on the higher ranges.

    Types of Shallow-Mount Subwoofer

    Powered

    A powered subwoofer includes an amplifier inside the enclosure, making it suitable for smaller spaces. These subwoofers have decent bass frequencies and overall sound; however, the small enclosure prevents them from emitting hard-hitting, super deep, and powerful bass tones. Their size and ease of installation is beneficial, particularly in compact spots.

    Component

    A component subwoofer has several separate parts and is geared towards audiophiles who want to customize their sound system. You have the freedom to choose what type of enclosure, amplifier, and other items you want to include. While this type of subwoofer is tailor-made to suit your needs, it takes a bit of technical skill to make it all work. A non-component subwoofer includes everything you need in one enclosure. This type of subwoofer is geared towards people who don't want to fuss too much with the installation.

    Enclosed

    An enclosed subwoofer is pre-mounted inside an enclosure that is specifically designed to contain it. Enclosed subwoofers do not include amplifiers, so you will need to purchase one separately. There are fewer enclosed subwoofers on the market than other options, but they're a great pick if you want a simple solution to upgrading your sound system.

    Vehicle-Specific

    Vehicle-specific subwoofers are tucked away in various locations such as the door in your car, truck, or SUV. If you don't have much space or want to put the subwoofer in an out-of-the-way spot, this is one way to do it. They typically match your vehicle's interior and come pre-mounted in an enclosure. However, they don't produce a big, booming bass sound compared to larger subwoofers.

    Shallow-Mount Subwoofer Pricing

    • Under $50: This price range tends to include 8-inch subwoofers. While they may be small, a great subwoofer will add more sound and work better than a factory sub, but it won't necessarily have the performance or quality of more expensive brands.
    • $50-$150: Here you’ll start to pay for some of the more popular name brand subwoofers. They feature several options for delivering great-quality sound at a good price. Those options are the design of the cone, the type of material used to build the speaker, and the size of the subwoofer.
    • Over $150: These are the top-of-the-line, best-quality subwoofers. They’ll be louder and offer more peak power and RMS. Most will be long-lasting with superior sound quality and performance.

    Key Features

    Size

    Vehicle subwoofers vary in size from 8 to 15 inches. Typically, larger subwoofers have louder bass, but that's not always the case. The size also impacts peak power and RMS. The larger the speaker, the more difficult it may be to mount in your car. A shallow-mount speaker doesn’t take up a lot of space, so it’s ideal for smaller cars and can fit more compact places.

    Frequency Range

    A subwoofer is limited to the frequency range it can attain. A subwoofer with a smaller lower limit will produce deeper, lower frequencies. If you're looking for really deep bass, choose a sub with the lowest frequency limit.

    Single- vs. Dual-Voice Coils

    Single-voice coils are useful if you want a quick and simple upgrade to your audio system. Dual-voice coils give you flexibility when it comes to adding additional sound outputs. If you enjoy customizing your stereo to find the best sound, consider dual-voice coils.

    Power

    Every subwoofer has a wattage rating that demonstrates how much power it can handle. It should be noted that this rating is for peak performance. A subwoofer that operates at its highest rating for an extended period of time will eventually overheat and fail. Look at the root mean square (RMS) to see how much power the sub can consistently handle.

    Other Considerations

    • Sensitivity Rating: To determine how powerful a subwoofer is, you need to look at the sensitivity value as well as the power rating. A sub with higher sensitivity is able to produce the same level of sound with a smaller amount of power compared to a sub with a lower sensitivity.
    • Enclosure Type: This is an important feature because it affects the subwoofer's quality of sound. How the sub is enclosed can also impact performance. The best subwoofer for a sealed box, for example, will generate the deepest base, while a ported enclosure and bandpass enclosure will permit higher levels of volume.

    Tips

    • Tuning your system after installing a subwoofer is a must to get the max amount of power. If your system has other amplifiers, you will need to tune them separately to get the sound you desire.
    • If you hear distortion, turn down the sub amp gain to get a cleaner sound. If you are not getting enough bass out of the subwoofer without distortion, you may need a larger subwoofer and amplifier.
    • If your subwoofer doesn’t appear to be performing at its peak volume, don't lower the gain on your amplifier to compensate. If you do this, your full-range speakers will not produce the clean, full sound that you want.
    • If you really want tighter bass and more clarity from your car audio system, upgrade all of the factory speakers on your vehicle. It will make a huge difference in overall performance.
    • If you don't have a premade enclosure for your subwoofer, you can build a box. Just make sure it's sealed properly because leaks can affect performance. Also, the box should have the correct interior volume in relation to the sub.

    FAQs

    Q: Which shape is best: round, square, or triangular?

    A: This really depends on your style and preference. Square subwoofers reproduce bass incredibly well and look stylish. Triangular subwoofers also reproduce bass very well and have the advantage of being able to fit in tight spaces. Traditional round subwoofers reproduce bass effectively with the advantage of playing more precisely.

    Q: Does the type of enclosure make a difference? 

    A: Enclosures greatly affect the sound of the bass. Most enclosed subwoofers come contained in pre-mounted boxes, but many require you to order their own or build it yourself. To get more volume, try ported or bandpass enclosures. If you want to get a deep, low frequency, choose a sub in a sealed box.

    Q: Does a subwoofer need an amp? 

    A: This depends on the amount of peak power and RMS the subwoofer is rated for. A powered subwoofer usually has a speaker and amplifier within the enclosure. They're ideal if you have a small vehicle without a lot of space for a separate speaker and amplifier system. You’ll need a more powerful amplifier to really get the best performance from your subwoofer.

    Q: Does the material of the subwoofer cone make a difference?  

    A: The material of the subwoofer can have an impact on the sound. The cone of a sub varies in construction. They can be paper, synthetics, or composites. Paper is less durable but is lightweight and has a quick response. Overall, most types of material work just fine and produce equally great sound.

    Final Thoughts

    If you want to get the best bass sound out of your car but need a high-quality subwoofer, we recommend the Rockford Fosgate P3SD2-8 Punch Series Shallow-Mount Car Subwoofer.
