A truck’s stock speakers have decent sound quality, but they may be missing something. Perhaps they can’t produce the low frequencies that give your music that extra punch you can feel in your gut. Truck subs are designed to reproduce the extra-low frequencies from your audio system. Check out our selection of the best truck subwoofers in the buying guide below.

Best Overall

Dual Electronics BP1204 illumiNITE Enclosed Car Subwoofers

Honorable Mention

  Kenwood KSC-PSW8 Under Seat Powered Subwoofer

This truck subwoofer is a great addition to car audio systems that lack a subwoofer. Its good frequency response range (35 to 150 Hz) contributes to its superior sound. It easily fits under the driver or passenger seat.
It has a slim profile and pumps out a lot of bass. It can be installed in a variety of trucks and its wired remote allows you to make minor tweaks to your music. You can change the volume, frequency, and phase. The speaker is very easy to install and can fit under the rear seats of some trucks.
It may start producing a fluttering noise after a while. The bass may also start to get muddy, even at moderate volume. The inline fuse is of low quality and hard-wired into the power line.

Benefits of Truck Subs

  • Better sound. Installing an aftermarket subwoofer will let you achieve better sound quality by using better quality equipment than stock.
  • More control. The sound system in your car is designed to achieve a decent sound that will appeal to the vast majority of people. Aftermarket subwoofers give you more control over the sound to customize it to your taste and music preferences. 
  • Accurate sound. A subwoofer is a dedicated speaker to the lower spectrum of tones. This allows it to have better accuracy in the sounds that it produces. Instead of trying to achieve several levels of sound, its components are designed for a small subset. 

Types of Truck Subs


This is the stand-alone speaker that you’ll need to install into a subwoofer box for correct operation. You’ll also need to buy an external amplifier. If you’re looking to design a completely custom system from the ground up, then this is the way to go. You’ll find they range in size from 8 to 15 inches and can function on low to high power. 


These subs come pre-mounted in a subwoofer box. This makes for easier installation since it takes a step out of the process for you. The downside is that you’re stuck with the options that are on the market, and they may not work for your particular vehicle. You’ll also still need an external amp for power. 


Powered subs come with the box enclosure and the amplifier built-in. This makes installation even easier since everything is built into one unit. They also tend to be quite compact in size, which makes finding a place in your vehicle to accommodate it even easier. The downside is that they may not produce that big, heavy thumping bass that you’re looking for. They’re better suited as a factory add-on piece than a custom system component. 


Some subs are manufactured with a specific vehicle in mind. They can come either powered or unpowered. You’ll find that they go in a specific place in your car. They’ll be color-matched and designed to fit seamlessly into your vehicle’s interior. They may not be as powerful as the component subs, but they’ll deliver plenty of bass and work for most car owners.

Truck Subs Pricing

  • Under $50: You can find stand-alone component subwoofers in this price range. You can also find empty enclosures in this price range. The car speakers are 10 inches and under, from reputable companies, and come with basic functionality. 
  • $50 to $100: In this range, you’ll find smaller speakers with greater functionality and larger speakers with basic functionality. You’ll also find dual subwoofer enclosures.  
  • $100 to $500: These speakers range in size but have more features and refined performance. You’ll also find all-in-one units that have the subwoofer and amplifier contained inside the housing. As you move higher in this price range, you’ll find better-quality subs. 
  • Over $500: These are specialty component subs that are designed for someone wanting to create an entire sound system from the ground up. These speakers are typically an unnecessary investment for the average truck owner. 

Key Features


If you’re looking for a system that has that teeth-rattling boom, then you need plenty of power. Look for the RMS rating and not the peak power rating. This will tell you the continuous power capabilities of the subwoofer and not what it can handle in power spikes. This is a more realistic measure of the output you can expect. 


After looking at power, you need to compare it to the subwoofer’s sensitivity rating. If the sub is more sensitive, then it needs less power to produce the same sound that a model with a lower sensitivity rating would need. This means you can increase sensitivity and lower your power needs. 

Frequency Range

This is the range of sounds that the sub can produce. It will tell you how low in tone the sub can go. But keep in mind that this is a subjective measurement. A lot of other variables will affect the performance of your sub and can limit this range. For example, the enclosure type can affect this. 

Other Considerations

  • Enclosure Type. A sealed box will give you the most accurate sound and enable you to achieve the deepest tones. A bandpass or ported box will give you more volume to the sound. The one you choose is about personal preference and the sound you’re aiming to achieve. 
  • Size. Ultimately, if space isn’t an issue and you want the loudest and deepest, then go for the biggest—but don’t get hung up on size. Smaller subs can produce plenty of bass if given the proper enclosure, supplied with the correct amount of power, and they have the right sensitivity. 
  • Impedance. You need to match your sub and amplifier in both power and impedance. A standard impedance rating is 4 ohms, but it’s becoming more common to see ratings of 2 ohms and 8 ohms. This measurement is the amount of pressure or load the electrical system can handle. You don’t want to over or under load your sub from the amplifier output. 

Best Truck Subs Reviews & Recommendations 2021

If you own a large truck and you like impressive speakers, you'll be delighted by these subwoofers. They do a lot more than just pump out great bass: their IllumiNITE lighting system produces a cool blue glow, making your vehicle look as great as it sounds. The speaker enclosure has a 12-volt input that powers the IllumiNITE system. An on/off toggle switch allows you to control all of the action.

The system's built-in protection circuitry keeps it safe. The 12-inch subs have polypropylene cones with a brushed chrome finish. The stamped steel baskets and foam surrounds ensure stability and control. We also like the carpet covering, mirrored chambers, plexiglass viewing windows, and 2.5-inch voice coils. If you want to feel like you're at a concert every time you hit the road, pair this speaker system with the right amp.

However, the dimensions of these subwoofers make installation challenging. In addition, the system has a peak power of 1100 watts, but it may blow if you connect it to a 1100-watt amp. The manufacturer provides no spare parts, so you must be careful when handling it.

Kenwood is a respected brand in the audio industry, and this subwoofer is a great option. The KSC-PSW8 takes the guesswork out of your audio upgrade. It is specially designed to produce great bass in less space. If you are not pleased with your truck’s sound system, take a look at this subwoofer. It fits under the seat in most vehicles, and its bass response is similar to that of a larger subwoofer.

This eight-inch Kenwood subwoofer is a great option for truck owners who want to enhance the bass of their audio systems without losing a lot of space. Its rigid enclosure eliminates rattles, while its sturdy, built-in amplifier gives it 150 watts RMS power. You’ll love the wired remote that Kenwood provides, as it allows you to control the bass from the driver's seat.

The sub has a frequency response of 35 to 150 Hz and a sensitivity rating of 81 dB. However, it may start producing a fluttering noise after a few months, and the bass may start to get muddy. The inline fuse Kenwood uses is also of low quality.

This 800-watt speaker system delivers crisp and clear bass in a small package. We love its deep impressive bass. It is CEA-2006 compliant, which means that it has been tested by the Consumer Electronics Association and it produces the power the manufacturer says it does. It features high-level inputs that make it easy for you to turn it on and off.

Installing a subwoofer in a truck is not easy because most people don't know where to install one in the first place. Rockville made the job simpler by creating a compact subwoofer at only 2.7 inches thick that fits under the driver's or passenger's seat. It has a thermal protection circuit, a short protection circuit, and an overload protection circuit.

The sub has awesome controls that allow you to modify the sound to your liking. It also comes with a 30-day money-back guarantee. But it has a few downsides. For starters, it is not very durable. After using it for several months, it may start to cut off, shut off, or not turn on at all. It may also get hot if you feed it with 5V or more from a head unit.

The Rws12ca has a powerful amplifier and a sturdy enclosure for optimal bass reproduction. It features a 150Mv - 5V variable input level and automatic turn-on circuitry and easily pairs with any factory system with little wiring. You can easily install and remove the speaker thanks to its angled terminals. It has high-level and low-level inputs for integration with factory and aftermarket head units.

This super slim sub has a power handling capacity of 300 watts RMS and 1200 watts peak. It has a low pass crossover frequency range of 50hz-250hz and a 4-ohm impedance. We like its adjustable low-pass crossover, remote bass control, and gain control range. You can install it in a car’s trunk or under a truck’s seats.

This is one of the smallest subwoofers manufactured by Rockville, but don’t let its small size fool you: it produces very intense bass. However, it tends to heat up very quickly because it lacks a built-in fan. It also has a poor bass response compared to other speakers with similar specifications.

Kicker designed the 44TCWC104 to produce a lot of bass in a limited space. It fits perfectly under or behind the seat of a truck and produces powerful bass. The deep-sounding and high-performance subwoofer works well in a shallow enclosure. It has a flex-resistant cone and delivers low frequencies without distortion. Its foam surround helps keep the cone in place.

This speaker system will add muscle to your music. Its rugged, ported box allows it to produce crisp and clear sound no matter what type of music you play. Its strong steel basket creates a good foundation for big bass, while the venting ensures it doesn't blow when the bass gets heavy.

Medium-density fiberboard gives the enclosure a long lifespan. However, we don't like how the bass sounds when the volume is turned up. You also have to connect the speaker to an amp pushing less than 300 watts or it may blow after a short while.

Don't let its compact size fool you—this 10-inch Rockford Fosgate sub means serious business. It has an RMS output of 200 watts and is one of our top picks for a truck. Paired with a slim enclosure, it can be installed in compact trunk spaces or behind the seats of trucks. The subwoofer has a 2-ohm impedance.

Rockford Fosgate has become very popular in recent years, and both Ford and Mitsubishi use its audio systems in their cars. Its midrange subs are not expensive and have solid sound quality. This speaker has a well-built enclosure and distributes sound very well. The enclosure is covered with a high-density carpet and has quick-release compression terminals.

However, we’re not too pleased with the bass response. Even when you turn up the volume, the bass sounds more like treble. The sub may also start to produce a rattling noise after a while, and if you connect it to a powerful amp, the sound may get distorted.

The JBL BassPro SL Under-Seat Compact Subwoofer delivers impressive bass from a low-profile enclosure that fits under the seats of many vehicles. Its eight-inch woofer puts out some strong bass.

The sub features a Class D amplifier that feeds it with 125 watts RMS power. Because the amplifier does not get warm when running, you can install the subwoofer under a seat or in another tight space in your truck. The amp's features include adjustable frequency and bass boost. Speaker-level and line-level inputs with an input load switch enhance its functionality.

However, we feel it is worth mentioning that this sub does not fit under the seat of every vehicle. For instance, you may want to get another under-seat speaker if you own a Jeep. It also lacks a good bass response, and its price is on the higher side.


  • When shopping for a truck sub, take measurements of the space where you will put it. If you’re going to build your own sub enclosure, take backspacing into account as well as speaker diameter.
  • A speaker’s peak power rating isn’t what it can constantly reproduce. The peak power rating is a speaker’s ability to produce instantaneous punches. The power output that a speaker can handle is known as its RMS (Root Mean Square) rating and is typically about half of its peak power rating.
  • Pay attention to magnet size when shopping for a truck sub. Question a high peak power rating if the speaker has a small magnet.


Q: Can I mix and match components when building a stereo system?

A: Yes. You can buy a matched kit from a single brand, or you can piece your truck’s stereo system together with components from a number of brands. 

 Q: Do I need a crossover with a subwoofer?

A: Yes. Subwoofers are designed to produce sound in a specific frequency range. Forcing them to produce sound outside of that range can damage them. Most modern amplifiers have a built-in crossover or band-pass filter to keep highs and midranges from ruining your subwoofers.

Q: Do all truck subs come with an amplifier?

A: No. You can buy individual component truck speakers by themselves all the way up to complete truck subwoofer systems that come with the amplifier, subwoofer, and installation wires.
