The Best Subwoofer for Cars

Unlike normal speakers, subs operate between 20-200 Hz, producing deeper tones to add power to your beloved music. If this is what your car stereo needs, then you might find the perfect match after taking a look at the following products.

1. Rockville RW10CA 10" 800 Watt Slim Low Profile Active Powered Car Subwoofer Sub, Black

Let’s start our reviews with this monster that has taken the market by storm. The Rockville RW10CA is a tiny thing, but its performance overpowers its mini size.

The 800-watt sub produces tones ranging from 50 Hz to 150 Hz, ensuring that you hear all those desirable bass sounds. As one user pointed out, the Rockville subwoofer was able to fill an entire pick-up truck with deep tones after they’d installed it under the seats.

Plus, we like how the control knob is easy to use so that you can reach your preferred level of bass. This can be pretty useful when switching between different songs with various genres. What goes with metal doesn’t always work with punk, right?

Another thing to admire about the Rockville car subwoofer is that it's made of top-quality materials. Furthermore, it’s pretty simple to install, but the package doesn’t include the wires, so you’ll have to get those separately.

To give your bass a basic boost, we recommend you get this sub by Rockville. However, if you’re a dedicated audiophile, you may want to look for something with more than just decent sound quality.

  • Huge frequency response for a great listening experience
  • Brushed aluminum cones for a long lifespan
  • Comes with blue LED light for a nightclub-like effect

This 12-inch sub can produce 600 watts of output power. While that’s not the highest value out there, it’s still decent enough to shake your car seats and deliver awesome bass effects. Better yet, it can give you a sweet balance of deep bass and great sound quality.

6. Rockford Fosgate P1S4-12 Punch P1 SVC 4 Ohm 12-Inch 250 Watts RMS 500 Watts Peak Subwoofer

Looking for a more budget-friendly option that promises decent performance? The Rockford Fosgate Punch subwoofer might be what you need.

This buddy here can handle 50 to 250-watt RMS, which can be ideal for a car owner who enjoys music on long rides. An audiophile will probably need more power, though, so keep that in mind if that’s the case with you.

Still, if you attach this sub to a good amplifier, you may have the chance to affect its bass output a great deal. And, with its Kevlar-reinforced paper cone, the sound should be as accurate as it can be at such an affordable price.

However, many users noted that the performance wasn’t best when you crank the volume too high.

All in all, the Rockford Fosgate Punch subwoofer can boost your pre-existent car stereo system. So, it’s a good option for those who’ll settle for a little upgrade and not an all-out transformation.


  • Combines admirable performance and an affordable price
  • Handles up to 50 to 250-watt RMS
  • Suitable for a basic stereo system upgrade
  • 1-year warranty
  • Budget-friendly

7. Rockville SS8P 400w 8" Slim Under-Seat Active Powered Car/Truck Subwoofer Sub,Black

Here’s another rather affordable subwoofer that can fit perfectly under your car seat. Made by Rockville, this little buddy here packs more power than a lot of people have presumed.

It all starts with the SS8P’s performance, which many have described as surprising. The sub can give your car’s factory stereo system an extra kick, especially if it’s not connected to any amps.

However, because the subwoofer only handles a peak power of 400 watts, it won’t exactly keep up with loud volumes. It will easily be overpowered, resulting in distortion. So, if you want to improve the bass feel slightly in your car, this Rockville sub should do it.

We like how the unit is encased in a cast aluminum enclosure. This should keep the sub from heating up, not to mention that this strong body can withstand years of wear-and-tear by your side.

Overall, the majority of people who tried this sub thought it represented good value for the price. So, if you want something that balances decent sound quality and a reasonable price, the Rockville sub may be your best option.


  • 8-inch slim body for easy positioning in your car
  • Handles 400-watts of peak power
  • Heavy-duty mounting feet to eliminate vibrations
  • Adjustable input sensitivity to match each taste
  • Produces sound ranging from 50 Hz to 150 Hz
  • Budget-friendly


  • Doesn’t function properly at loud volumes
  • Moderate sound quality

How to Choose the Best Subwoofer for Your Car

After taking note of many awesome products on the market, it’s time to pick one. But which sub should you go for? And how should you think in order to purchase the best product for your individual use?

In this section, we’ll go through several factors that you need to consider before buying a car subwoofer. This way, your decision should be a piece of cake to make.

Type of Subwoofer

Subwoofers are available in various types, so you must pick one that matches your preferences. Here are the four types of subs on the market.

Enclosed Subwoofer

This is a sub that comes in an enclosure, and it can be suitable for those who aren’t fans of customizing their speakers. An enclosed subwoofer still requires an external amplifier to deliver a desirable level of power, though.

You can find this type of sub with several styles and designs, but not as many as you’d get with other subwoofer types.

Component Subwoofer

Component subwoofers are simply every audiophile’s dream. Basically, a component sub is a speaker that brings out all the beloved bass in a song. So, in order to put it to work, you’ll have to mount it inside of an enclosure and hook it to an amplifier for power.

Of course, component subwoofers give users maximum freedom to create custom sound systems. So, if you’re ready to build a stereo system for your car from scratch, you should go for one of these subs.

A component subwoofer comes in many sizes, usually from 8 to 15 inches. Also, it’s available in a huge variety of impedance, voice coils, and installation options. Therefore, it shouldn’t be much trouble trying to find the right one for your vehicle.

Powered Subwoofer

Powered subs are the easiest when it comes to installation. Basically, these include everything you might need to enhance the bass of your sound system without having to buy extra products.

For example, a powered subwoofer comes in an enclosure. Not just that, it’s also connected to a built-in amplifier to keep you from going around in circles trying to find the perfect fit. Another positive point is that this sub usually takes minimal space in your car.

However, a powered sub leaves no room for personalization, which will probably not appeal to an audio fanatic. Plus, this sub doesn’t always produce the best bass output.

Vehicle-Specific Subwoofer

The last type of subwoofer you’ll find on the market is the vehicle-specific sub. As the name implies, this sub is designed with certain vehicle models in mind to save space.

Most of the time, a vehicle-specific subwoofer is intended for unused spaces in a car, such as the areas under the seats. So, you can install them without diving too deep into your car’s interiors.

These subwoofers deliver decent output, but again, they don’t produce the same sound quality as the previous sub types.


When shopping for a car sub, the most common sizes you’ll come across are 8, 10, 12, and 15-inch units. This begs an important question. Which sub size to buy for your car?

Well, your choice will depend on your musical preferences since the dimensions of a sub will affect its output. Let’s find out what each size promises regarding your listening experience.

8-Inch Subwoofers

The smaller a sub is, the faster its response will be. As a result, 8-inch subs can work best with fast-paced music, complimenting your audio rather than making your bass overpowering.

8-inch subs can be ideal for those who enjoy a light touch of bass. So, if you’re all about heavy and deep bass that shakes the windows and mirrors, you’ll want to go for a larger sub.

10-Inch Subwoofers

A 10-inch sub can be a perfect choice if you want the best of both worlds. The most common on the market, this subwoofer works great with fast-paced music while giving it more bass than an 8-inch sub.

You could listen to rock, rap, electronic, or club music using a 10-inch sub. Of course, people who prefer incredible heavy bass might want a stronger sub to deliver mirror-shaking effects.

12-Inch Subwoofers

Now, things will start to get heavy. A 12-inch sub can keep up with all types of music out there, but it may not be as great as a 10-inch sub is with fast beats. So, it might not be the best with rock music, but it should be wonderful with pop, rap, club, etc.

A 12-inch car subwoofer is sure to vibrate your windshield because it produces heavy bass. So, if you’re preparing for an SPL competition, you should probably consider investing in it.

15-Inch Subwoofers

15-inch subs aren’t so popular amongst subwoofer sizes, but they’re still available if you want to buy one. These beasts deliver the heaviest bass out of all subwoofer types, which may not appeal to people who need a sub for everyday use.

Still, if you want the deepest output you could find, a 15-inch sub will do. Just be careful not to break anything while listening to your favorite Eminem tracks!

Power Handling

It’s crucial that you understand how much power a sub could handle. If not, you might end up with a subwoofer that it’s compatible with the amount of power that it receives. Ultimately, this could distort your music or damage your speakers.

Pay attention to the RMS power handling. It’s an indicator of the amount of power a sub could manage continuously.

You may want to take a look at the peak power handling as well, which refers to the power a sub can handle in short bursts. However, RMS values are more important to note since they’re related to your overall listening experience.


Last but not least, you must make sure that the materials of your sub are up to standards. Not only will they ensure that your unit lives long, but they also have effects on the sound output.

It’s best to go for lightweight materials with the woofer itself. These will raise the responsiveness and quality of your bass. Polypropylene, kevlar, and carbon are suitable materials for the cone.

However, if you want a high-end product, you could invest in a titanium or aluminum woofer cone instead.

As for the woofer surrounding, you’ll need a material that combines durability, lightness, and freedom of motion. A too-solid material will soon crack as the speaker vibrates with music. So, you’ll want something more flexible such as rubber.

You could also go for foam or cloth surroundings since they come with more affordable subs. Yet, these two materials have shorter lifespans than rubber.


Does the sub enclosure type affect its performance?

Of course. Enclosed subwoofers come in either sealed or ported boxes, and each one of those has a direct effect on the sub’s output.

For instance, a sealed enclosure helps the sub deliver deeper and more accurate sounds. On the other hand, a ported enclosure performs better in terms of volume.

How does a subwoofer’s sensitivity impact its output?

Sensitivity works with your sub’s power to give you the best bass output. So, you’ll need to find a good balance between both factors to end up with desirable results.

Generally speaking, a subwoofer that has a higher sensitivity rating needs less power to give you the same amount of sound as a sub with a lower rating.

To Wrap It Up

Finding the best subwoofer for car use may seem a bit tricky at a first glance, especially if you don’t have much experience in this field. Hopefully, we were able to make the picture clearer so that you can make a well-thought choice.

As for our favorite pick, it’s the Focal SUBP25F 10” Flax Cone Subwoofer. We love its immense power, top-notch materials, and sturdy build.

However, if you’d prefer something a bit more affordable, we suggest you go for the Alpine RW10D2 10″ Coil Subwoofer instead. Not only does it offer great value for the money, but it also produces up to 750 watts of RMS. That’s pretty impressive at this price point.

Now, it’s time for you to choose your top pick and bathe your car in bass!
