6 Best Car Subwoofers of 2021

Looking to fall in love with your music all over again? Then you need to discover the bass in your favorite songs. From the powerful thump of string instruments to the low bell of a cello, bass is there in all genres, and the only way you can feel it is by adding a subwoofer.

The reason we’re saying that is because built-in car speakers generally have trouble reproducing low-frequency sound. Their small size makes then unable to play those lower frequencies the way a recording artist singer wanted them to sound. This restriction negatively impacts their sound quality.

Luckily, that isn’t the case with the best subwoofers for cars. These products are designed to reproduce frequencies below 80 Hz, a range even high-quality aftermarket speakers cannot reach. They are your entry pass to deep, vibrant music on the go.

Subwoofer for Car Buying Guide

Whether you’re investing in a car subwoofer to enjoy every bump and thump in your favorite tunes or you’re simply looking to blast your music at window-shattering levels, there are a few questions you need to ask yourself before making the purchase. Scroll down to see them.

Once you’re done answering all those questions, you’d better understand the need for features that we have listed as a must-have for a high-quality sub.

5 Considerations When Buying a Car Subwoofer

Here are some of the essential questions you need to ask yourself before you start searching for a car subwoofer:

  1. How much power does my subwoofer system need to have?

    The answer to this question depends on the sound system you’re currently using. Factory speakers or built-in dash stereos can easily blend with less powerful subwoofers. Aftermarket receivers and amplified receivers will need a subwoofer with more juice.
    For instance:

    • If you have a factory radio: Your subwoofer needs to provide only 50 to 200 watts RMS of power to ensure adequate bass.
    • If you have an aftermarket speaker: You should be looking at a subwoofer with 200 to 300 watts RMS of power.
    • If you have amplified speakers: Subwoofers providing 250 to 500 watts RMS of power are a good starting point
    • If your system has 100 watts RMS per channel: You shouldn’t settle for any subwoofer with less than 1,000 watts RMS of power.
  2. What kind of enclosure should I get?

    It isn’t only the sub’s inner components that affect its sound quality and volume of bass. The style of the enclosure the sub is mounted in also plays a crucial role in the richness of the bass that the subwoofer will be churning out. Here’s why we’re saying that.

    To protect the bass, the enclosure’s design must ensure the separation of sound waves produced at the front of the speaker from the ones produced at the back. If the enclosure’s design is faulty, it will fail to do its job and both the sound waves will cancel each other.

    Subsequently, both of them will go ‘out of phase’ and your system’s bass response will be weak, if not outright poor. That is why you need to pay attention to the style of the enclosure the subwoofer is mounted in.
    With these facts in mind, let’s look at the various styles of enclosures:

    • Sealed Enclosure:

      These enclosures are airtight from all sides and provide deeper, precise bass and more accurate sound. However, since their driver is continuously putting pressure on the diaphragm due to its movement, they require more power for high volume.

    • Ported Enclosure:

      They are louder than sealed enclosures, require less power and produce more boom. Listeners of hip-hop, rap and R&B music will find them as a better option. On the flip side, they are harder to tune and require you to use a subsonic filter on the amp to get bright tunes.

    • Bandpass Enclosure:

      Their dual-chambered design (one chamber sealed, other ported) allows bandpass enclosures to produce extra loud sound. Audiophiles who want nothing but the maximum slam as well as listeners of hard rock, rap and reggae will find them extremely useful.

  3. What is the material of construction of the subwoofer’s cone?

    Also known as subwoofer diaphragm, the cones are critical to the overall performance of the sub. Experts tell us that the main requirements for cones are that they should be rigid, but low mass. They should also be self-damping to minimize the effects of self-resonance.

    Like their counterparts used in speakers, subwoofer cones are also made of various materials, including treated paper, composites (like injection-molded quartz) or synthetics. Paper is lightweight in construction and less durable, but its responsiveness is rapid.

    Synthetic cones are more rigid than paper cones and are exceptionally damped. They boast a controlled breakup and provide a smoother high-end roll-off. Remember, all these materials work great, so you need to play different genres to determine the cone that’s right for you.

  4. What kind of subwoofer should I get?

    If you intend to build a truly personalized system, you’d be better off with component subwoofers. These subs consist of only the speaker and range in size between 8’’ and 15’’. They require you to mount them in a dedicated subwoofer box or else they won’t operate properly.

    Provided you are looking for a system that comes pre-mounted in a box, check out enclosed subs. They don’t require you to do much work designing your system. However, the number of speakers that they provide is limited and like the component sub, you’d have to power them with an external amp.

    Lastly, if all you want is a simple, space-saving bass system, you might want to go with powered subs. These models have a built-in amplifier, don’t take much space and are a cinch to install. Having said that, they may not be the right option for you if you’re a fan of massive bass.

  5. What is the material of the surround?

    Every subwoofer has a cone that moves back and forth to produce the sound. The suspension that holds the cone in place while also letting it move freely is called the surround. The material of the surround must be durable. Otherwise, it won’t stand up to the extremes of bass.

    Surrounds that are made of foam withstand massive excursion and don’t warp over time. They are also super lightweight and are often blended with other materials to improve their overall strength. Those that are made of rubber might warp over time if they aren’t mixed with other synthetic materials.

  6. What should be the size of my subwoofer?

    If space isn’t an issue and you are looking for a sub that plays extremely loud, go for the biggest model. But that isn’t to say that smaller subs are inferior. They can also churn out plenty of sound if they are mounted in the right enclosure and are correctly wired.

A List of the Most Important Car Subwoofer Features and Specs

Following are the features and specs which almost all top-rated car subwoofers possess:

  • Adequate Power:
    You need to make sure that the power of the system you’re looking at is equal to your amp’s RMS power. Only then you can count on the sub to be able to handle your system’s output power.
  • High sensitivity:
    Assuming your sub has a higher sensitivity rating, it will require less power to produce the same amount of sound as another sub with a lower sensitivity rating. That’s why you should always go for a model that has a higher sensitivity rating.
  • Dual voice coil:
    Subwoofers that have a dual voice coil (DVC) are incredibly flexible as far as their wiring is concerned. Their parallel wiring arrangement lets you connect multiple amps to the same output without much impedance loss. It also ensures maximum amplifier output.
  • Wide frequency range:
    The more comprehensive the frequency range of a subwoofer, the better will be its ability to play both lows and highs of the bass sequence. That’s why we recommend that you go for a sub with a wide frequency range.

Car Subwoofer Sizes: 10-Inch Subwoofers Vs 12-Inch Subwoofers

Although subwoofers are available in multiple sizes, the most popular sizes among the car owners are the 10-inch subs and 12-inch subs. Let’s have a brief look at both:

  • 10-Inch Subwoofers

    Users who want a little extra power but not at the cost of sound quality might prefer these subs. They have the ability to inject life to your music whether you frequently listen to metal, pop, jazz and even blues.
    You can also count on them to draw in additional air to provide a quick response to heavy drums that are found in these types of music genres. They are also a bit punchier than 12-inch subs.

  • 12-Inch Subwoofers

    Those of you who have a voracious bass appetite might praise what the 12-inch subs have to offer. They are capable of generating extra bass and work excellently with a lot of frequencies.
    At the same time, their relatively large size makes them less responsive, and due to this reason, 12-inch subs are best suited for low-lying music such as Rhythm and RnB.

Active vs Passive Subwoofers

Subwoofers can be categorized into two types: active and passive. An active subwoofer is one that has an internal amplifier. It is also known as a powered sub and requires only one wire connection for it to connect to your car’s receiver.

A passive subwoofer, meanwhile, must be powered by an external amplifier. The limitations of the amplifier project themselves onto that of the sub – which is why you need to select a high-quality amp to work with your passive sub if you want better sound quality.

Having got their definitions out of the way, let’s look at the differences between both:

  • Design and construction: Active subwoofers have their amplifier and speaker housed in the same enclosure. That isn’t the case with passive subs. Their enclosure only has a speaker, with the amp residing outside.
  • Ease of installation: Passive subwoofers are more challenging to install than active subs. That’s because apart from connecting their components with the speaker, you also have to connect an external amp to the subwoofer. This means that you’d be dealing with more wiring.
  • Power consumption: Experts tell us that active subwoofers consume more power (watts) than their passive counterparts. They put a massive power load on the receiver to get the required power for their tweeter speakers and the mid-range.
  • Cost: Most of us juxtapose the price tags of both subs before announcing that the passive ones cost less. That is not true. You need to purchase an extra amp with passive subs whose price, when added to the price of the sub, makes it an expensive option.

What is the Difference Between a Woofer and a Subwoofer?

A woofer is basically a loudspeaker with a frequency range between 40 and 2,500 Hz. It is capable of playing both low as well as mid-range frequencies. It is ideal for use in a setup like home theater where you have a more extensive range of sounds that could fully exploit the woofer’s dynamic range.

Subwoofers, meanwhile, are meant to reproduce low-pitched sound frequencies. Their focus on the lower frequencies – between 20 and 200 Hz – allows the subwoofers to crank a constant bass for most tunes. It also allows them to make the bass of your music easier to notice.

Even though the frequencies of both of them can overlap in some cases, the application of each will be different. While the subwoofers add a more consistent and wider range when used in conjunction with tweeter and drivers, woofers provide a dynamic range alongside a home theater system.

Putting everything that we said in the previous three paragraphs in perspective, one can say that woofer is a ‘specialized speaker’ and the subwoofer is a ‘specialized woofer’. Both of them cover a narrow frequency range of the model they are specialized from.

FAQs and Answers

  1. Q: Why has my subwoofer blown out?
    A: There are two reasons why your sub might have blown out. The first is that you may have over-blown it. That means that you regularly played music at a level that was above and beyond its voice coil’s limit. Eventually, it burned out.
    The second reason involves the subwoofer receiving too much of a distorted signal. That hissing, gritty or crackling sound that you hear coming out from the speaker can burn out the subwoofer no matter what the volume.
  2. Q: How to position your subwoofer for loud bass?
    A: Here are two common positions where you can mount your sub in your car:

    • Facing the boot in the rear of the car: By placing your model behind the last row of seats, facing towards the boot, you’re allowing the subwoofer to offer bass that is evenly distributed across your car and is more pronounced as a result.
    • Facing upwards in the trunk hatch: Looking to save some space in your boot? Then mount your sub upward. This position will allow the subwoofer to offer big bass without consuming a lot of space. It will also prevent it from rattling loose parts in your car.
  3. Q: Should I install my subwoofer myself or pay for professional installation
    A: Most subwoofers that you see in this review are a cinch to install. They come with all the instructions you’ll ever need to mount them using a few tools, such as screws, clamps etc. However, if you have never installed an audio-equipment before, it’s probably a good idea to hire a professional.
  4. Q: Does the positioning of the vent (middle, top, bottom, or off to the side) affect sound quality?
    A: Experts tell us that as long as the vent can freely move the air in and out of the subwoofer, it won’t have any effect on the sound quality.
  5. Q: Should I use mono amplifier or multi-channel amplifier to power my subwoofer?
    A: To answer this question, let’s have a brief look at both the types of amps:

    • Mono Amp: These amps are compatible with almost all subwoofer configurations. Their design is such that it enables them to process low frequencies with ease. Aside from that, they boast excellent efficiency and have a high power-to-heat ratio.
    • Multi-channel amps: While the mono amps are designed to work with 2-ohms loads, multi-channel amplifiers are designed to run at 4 ohms. You must keep this difference in mind as it rules out the possibility of bridging multiple sub-2-ohm woofers with a multichannel amp.


Although subwoofers aren’t treated as a vital part of a car’s audio system, you should treat them as such if you want to enjoy mind-blowing music. They emphasize and reproduce the low-end frequencies whose presence in the music injects more life and vibrancy into it.

In addition to that, the best subwoofers for cars allow you to fully exploit all the plus points of your vehicle’s built-in audio system. Their components like low-pass filter and phase controls give you full control over the music you’re hearing.

That means that while most potential users view subwoofers as audio equipment that won’t do much more than rattling your windows, there’s more to this audio equipment than what meets the eye. You can go through the subwoofer for car reviews to make sure of that.
