Best Shallow Mount Subwoofer Reviews Right Now

Although shallow mount subwoofers are not a perfect solution, sometimes they are your only choice.

Whether you are on a budget or don’t have room for a larger unit, shallow mount subwoofers can be your gateway to better sound in your car.

With that in mind, let’s take a look at some of the best models we have found.

The Infinity REF1000S comes with exceptional installation flexibility. It is equipped with a low-profile design to fit into whatever type of enclosure you have.

In addition, the polypropylene woofer cones offer an excellent base even at frequencies lower than 25Hz.


  • RMS: 200 watt
  • Peak Power: 800 watt
  • Sensitivity: 89 dB
  • Frequency response: 35 - 175 Hz
  • Impedance: 2 or 4 ohms


The unique thing about the Infinity REF1000S is the Harman-proprietary SSITM (Selectable Smart Impedance). SSITM allows the subwoofer to give the amplifier the option of either 2or 4ohm with just the flip of a switch.

The provision of the two most often used impedance from the Infinity REF1000S makes it stand out from the other subwoofers. Infinity also made sure that this product was durable.



These are one of the best great-sounding subwoofers out there. They have a more oversized cone which gives you good bass. In addition, the 46L7T124 features the SoloKon square polypropylene that creates a rigid surface that does not flex hence minimizing distortion at high-level sounds.


  • RMS: 600Watts
  • Peak Power: 1200Watts
  • Sensitivity: 86.54 dB
  • Frequency response: 25-100 Hz
  • Impedance: 4ohms DVC


One of the incredible things about the Kicker 46L7T124 is the availability of various options when it comes to installation. Even if you have no experience, you can install this unit quickly and easily.

This subwoofer works under open or sealed enclosures. If you plan to wire this DVC sub at low impedance, ensure that your amp is compatible, as exceeding minimum impedance can destroy your amp.



While not quite at the same level as Alpine, Rockford Fosgate is really great about building high-quality audio equipment at a much more affordable price.

The saying is "you get what you pay for" right? Well, in this case it is "you get a freaking lot more than what you pay for, dude"

I'm far from hiding that I am a fan of Rockford Fosgate since a couple years back.

You see, they did damage their reputation something like 15 or so years ago when they moved manufacturing to china and quality dropped real hard.


  • RMS: 300Watts
  • Peak Power: 600Watts
  • Sensitivity: 83 dB
  • Frequency response: 45-250 Hz
  • Impedance: 4 ohms


Thankfully, I got to know RF years later when they already fixed that, so my experience has always been superb.

If you go for RF's more high-end components you should be ready to drop as many 100$ bills as with JL or Sundown, but for mid-level or even entry level as in this case, man the prices are so sweet.

This subs are sold in three different sizes, from 8 inches to 12 inches and although not so powerful as the TW Series from JL or the Alpine, you get a ton of bass.

Likewise, powering this subwoofers is quite easy with a decent 4 channel amplifier bridged or a 5 channel amp.

One of the things that have made me a brand advocate is that in every instance i've needed tech help, i've called customer support and got some great, great help and that is just so important when you're installing and then some question pops and freezes your whole project.



For good bass response, we would recommend the Pioneer Alphasonik AS8DF.

We recommend installing it downward to optimize bass response for deeper, heart-pounding rich sounds for excellent results.


  • RMS: 200 Watts, 600 Watts (Maximum)
  • Peak Power: 1800 Watts
  • Sensitivity: 90 db
  • Frequency response: 32Hz- 500Hz
  • Impedance: 4ohms 


The Pioneer Alphasonik AS8DF is durable courtesy of the MDF wood construction that also reduces vibration.

In addition to this, there is a special bond that creates airtight seals that improve joint strength and bass reflex. As a result, the aluminum cone can withstand the most influential bass notes.



This model comes with high strength foam surround and two layers of Conex spider to provide high-quality performance.

In addition, it offers impressive bass response regardless of the genre of music, so you can enjoy your music at all times.


  • RMS:  400Watts
  • Peak Power: 800Watts
  • Sensitivity: 85 dB
  • Frequency response: 25-500 Hz
  • Impedance: 2 ohms


The Skar Audio VD-8 D2 ultra-responsive motor (45 oz ferrite) offers a 2” voice coil hence allowing the subwoofer to hit every note and musical detail accurately.

In addition to this, the high temp 2” copper voice coil on this subwoofer allows it to deliver hard bass every time you play. This ensures good quality sounds in your automobile.



When talking about shallow mount subwoofers, most of them don’t come with any installation covering.

For the most part, the subwoofer is by itself and requires that you install it either exposed to the elements or put it where your old one was. In this case, the R2S-1X10 Subwoofer comes with a truck mount, which means that it has paneling surrounding it and comes with thick carpet to protect everything.


  • RMS: 200watts
  • Peak Power: 400Watts
  • Sensitivity: 83 dB
  • Frequency response: 38-250 Hz
  • Impedance: 2 ohms

Thus, if you want a subwoofer that won’t be totally exposed (and you have space), this may be a great option.


Another great thing about this particular model is that it produces excellent sound with minimal power requirements. That means that you should be able to install it into most compact sound systems and still get the deep bass that you deserve.



Our final stop is the Pioneer TSSWX2502 Subwoofer.

This is yet another 10-inch model, but it can pack a punch regarding the level of performance that you get from such a compact unit.

Pioneer is another high-quality audio brand, which means that you should feel confident when you install this subwoofer into your car.


  • RMS: 200Watts
  • Peak Power: 400Watts
  • Sensitivity: 83 dB
  • Frequency response: 38-250 Hz

Much like the R2S model above, this subwoofer comes with a truck mount attached. Thankfully, however, it is much easier to install in small spaces, and the mounting system is much more versatile, so you aren’t limited to a pickup truck cab.




Shallow Mount vs. Regular Subwoofers

shallow mount vs regular subwoofers

So what exactly is the difference between regular and shallow mount subwoofers? From the picture above I think you can clearly spot the most notable one: Size. 

Shallow mount subwoofers are considerably (wait for the surprise...) shallower than regular subwoofers. That advantage in trade is consequence of a trade in specs. Let's dive into it:


When talking about regular subwoofers, the benefit of installing that kind of unit into your vehicle is that you get a full range of sound.

Additionally, the sound quality and clarity will be better because it has more powerful components.

Better Xmax, bigger coils, usually higher RMS rates... that all means you get louder, clearer sound.

If you are a true audiophile, you will most likely want a standard subwoofer in your car.

As for shallow mount models, the biggest advantage of them is that they are much easier to put into your vehicle.

If you drive a truck, a sports car, or a compact vehicle, then you may be limited in options with regards to how much stuff you can cram into it.

Additionally, if you don’t want to have the added hassle and cost of mounting a standard subwoofer, you can use a shallow mount instead.


Standard subwoofers may provide you with the best quality, but the tradeoff is that they are more expensive and harder to install. Usually, to get a new subwoofer system into your car, you will have to take it to a certified installer who will take care of everything for you. You could try to do it yourself, but it is a rather complicated process.

Shallow mounts, on the other hand, make things much easier. But, their biggest disadvantage is that they won’t provide the same level of clarity or quality. You will notice a big difference if you install them, but you may not get as much as you would with a standard model.

Understanding Subwoofer Specs

For each unit that we will look at, we will provide all of the specs up front. In case you are not familiar, here is what each item means.

  • RMS (Root Mean Square) signifies the standard amount of power that is used for the unit.
  • Peak Power refers to the maximum amount that can go through the subwoofer with no damage
  • Sensitivity refers to how loud the unit can get with one watt of power.
  • Frequency Response means the range of sound that it can produce
  • Impedance means the electric resistance the voice coils offer. It should ALWAYS be paired to the impedance on which our amplifier is meant to work.

Best places to install your shallow mount subwoofer

When it comes to installing your new shallow mounts, you may be scratching your head as to where the best possible placement could be. To that end, we highly recommend two spots that have the best results.

  • Trunk: Depending on the size you go for and how big your trunk is, you may prefer to get the sub and enclosure on the trunk. The biggest advantage of this subwoofers is that they don't require a very big enclosure to work properly.
  • Underseat: Smaller sizes (8 and 10 inches) with really small enclosures may work under the seat of some vehicles, like vans or trucks. This really depends on the space available and if your really are thinking about getting the subwoofer under the seat I'd recommend you go for some of this ones instead.
  • Rear Speaker Deck: It's a simple solution, but I still prefer to mount the sub on an enclosure. It performs better.

Final Verdict

Overall, when trying to find the best shallow mount subwoofer for your car or truck, it will ultimately come down to space limitations and performance level we would suggest the PIONEER Alphasonik AS8DF model.

If you only have a little bit of room, however, then the Kicker Series is your best bet. If money is no object, then you have to go with Alpine, because they are the greatest.

7 thoughts on “Best Shallow Mount Subwoofer in 2022? (Top 5 Reviews & Comparison)”

  1. What are your thoughts on the Infinity 1000s shallow mount subwoofer? It did not make your list of best shallow mount subs. I have owned infinity subs in my last 4 builds. However my last build was about 8 years ago.

    I am building in a 2004 dodge ram 1500 quad cab. I will be using 1 10 inch sub in .5 cubic feet under one of the back seats. Driven with a mono fosgate 351m amp running 150 rms @ 4ohms or I believe 350 at 2 ohms.

    I have a separate fosgate 301x running MB Quart see ates in the front and MB Quarts 2 ways in the rear doors. I may replace them with infinity at some point.

    ThanK you for any help you may provide.

    • I’m not a big fan of Infinity personally.

      They made some decent gear a while back but they have gone downhill since. For shallow mount subs, they best option out there right now is the JL Audio TW5v2. Hands down the BEST shallow mount sub on the market by miles and honestly the 2nd best option would be the JL Audio TW3.

      The Sundown Audio SD-3 is also a decent option. I would steer clear of just about every other brand except those two when it comes specifically to shallow mounts.

      Hope this helps. Thanks.

  2. Hey Alex,
    I currently have a JL Stealthbox in my 2010 Jeep SRT8. The bass is decent, considering its being powered by a Alpine PDXV-9. I am looking to change the woofer in the box, as the 10w1v3 is decent, but I feel it should hit a little better. I tried fitting a 10w3 JL, but sadly, the box isn’t deep enough. What would you recommend to use? I’ve tried the Alpine shallow type R in my 2012 WRX, and blew it after about 3 weeks of use. I listen to everything from classic rock to 90’s hip hop and dance music. I use the crossover on the amplifier, and my EQ settings are flat.

    • Hi JC,, it sounds like you’re looking for a little more oomph from your sub.

      The Stealthbox from JL is a great choice, but it will only fit the JL Audio 10w3v3 in dual 2 ohm voice coil configuration. You mentioned that you’re using an Alpine PDXV-9.

      While that’s a nice amp, it tops out at 250 watts in the bridge configuration for the subwoofer. You have a few options for increasing your output.

      The first would be to get an amp that delivers closer to 400-500 watts for the sub channel, as the 10w3 can safely take about double the power its currently getting. If you can get access to an amp to test, it might be a good first step to add more power and see how it sounds. You should get a bit of a volume gain, but don’t expect huge results.

      If you feel like your system has reached it’s limits with that sub, I would suggest having a shop build a custom enclosure for a JL Audio 10w6 (or even a 10w7 if you really want to up the boom). You can use the same area as the stealthbox currently sits, without taking up too much space with a standard cube or rectangle box design. The JL 10w6v3 is an amazing woofer that has plenty of output while maintaining meticulous sound quality.

      The JL 10w7 is a great sound quality woofer as well and gets even louder than the 10w6. Whatever option you choose, you are going to need another amp since you’re not going to find another sub on par with the 10w3 that will get much louder with the amp you are currently using.

      I would recommend getting an amp that puts out 500-750 watts for the sub, by that I mean not including the power for the front speakers. You could keep your Alpine for the other speakers and just add a new amp for your sub as that would be the best way to get enough power to your sub.

      You could get another 5 Channel amp and switch it with the Alpine, but there’s not many 5 channel amps that put out the wattage you are going to need.

      The JL Audio Slash 600/1 amp is an excellent choice for both the 10w6 and 10w7 woofers.

      The JL Audio HD750/1 is also a great choice.

      The Alpine MRV-M1200 is also a good choice if you want to stay with Alpine for the amps.
      Those would be my recommendations for you. If you have any further questions, please don’t hesitate to ask! Thanks.

  3. I seen u didnt have the 12 inch Pioneer TS-SW3002S4. Whats ur opinion on them?And how do they compare to the 12 inch Jl audio tw3s? Which will give harder hitting bass? Thanks

  4. Hi

    Very good article!
    I’m trying to decide between the 12w1 and the 12tw1 for my sedan. I have enough space to fit both options but save space is always a good idea if the performance is not affected. However, according to what you wrote, even the tw1 been a smaller brother from the w3 with all the quality, the w1 (regular sub) problably will be better in performance, right?

    Best regards.

  5. I’ve been trying to find a comparison to the Rf power T1S1 and the L7T bit in 12in form factor…I know they are pricey, especially the T1…but I was surprised neither of these have been on any “Best Shallow Sub” list I’ve been able to find. Is there something I’m missing? If you had to choose, which way would you go? Any reason these were not on the list to begin with? Thanks for any insight you offer!
