What Do Subwoofers Do In A Car


What Do Subwoofers Do In A Car: To comprehend the significance of subwoofers, it’s essential to grasp the nature of low-frequency sound, often referred to as bass. Bass frequencies are the deep, rumbling tones that you can not only hear but also feel in your chest when they’re delivered with precision and power. These frequencies, typically ranging from 20 Hz to 200 Hz on the audio spectrum, provide the foundation and emotional depth of music and sound.

However, there’s a catch deep bass frequencies demand a substantial amount of energy to be reproduced faithfully. Standard car speakers, while capable of handling mid-range and high-frequency sounds admirably, often fall short in delivering the sheer force required for authentic bass. This is where subwoofers step onto the stage, offering a dedicated solution to fill this sonic gap.

Subwoofers feature larger diaphragms (or cones) compared to regular speakers. These diaphragms can move back and forth over a significant distance to displace air and generate low-frequency sound waves. Subwoofers are typically paired with dedicated amplifiers that provide the substantial power needed to drive the speaker’s cone with authority. This ensures that the bass is not only audible but also impactful. Subwoofers are designed to reproduce frequencies in the bass range with precision and clarity, delivering the fundamental tones that underpin music and movie soundtracks.

Does a subwoofer improve sound?

Music or movie aficionados looking for better bass performance from their home audio setup should get a subwoofer. With a sub, you’ll get more of the low bass frequencies than conventional loudspeakers or soundbars can deliver.

Enhanced Bass Performance: Subwoofers are specialized speakers designed to reproduce low-frequency sounds (bass) accurately and powerfully. They are capable of producing deep, resonant bass notes that smaller speakers cannot replicate. This results in a fuller, more immersive sound experience.

Balanced Audio: By offloading the task of reproducing low-frequency sounds to a dedicated subwoofer, the main speakers (often referred to as satellites) can focus on mid-range and high-frequency sounds. This division of labor results in a more balanced and clear audio output across the entire frequency spectrum.

Increased Sound Depth: Subwoofers add depth and dimension to music and movie soundtracks. You’ll not only hear the low-frequency instruments and effects but also feel their impact. This adds an emotional and visceral quality to the audio.

Do subwoofers make car louder?

Adding more subwoofers to a car can make it louder, but it depends on a few factors. Firstly, the size and power of the subwoofers will play a role in how much louder the car will be. Generally speaking, larger and more powerful subwoofers will produce louder and deeper bass.

Bass Impact: Subwoofers are designed to produce deep, powerful bass notes that are felt as much as they are heard. When subwoofers are properly integrated into an audio system, they can add a significant amount of impact and presence to the music. This gives the impression of a fuller and more immersive sound, which can make the audio experience feel “louder.”

Balanced Sound: Subwoofers work in conjunction with the main speakers (satellites) to create a balanced audio output. By handling the demanding low-frequency sounds, subwoofers allow the main speakers to focus on mid-range and high-frequency sounds. This balance ensures that all frequencies are reproduced effectively, contributing to a more dynamic and clear sound.

Perceived Loudness: Human perception of loudness is influenced by various factors, including the frequency and volume of sound. Subwoofers, by reproducing the low-frequency range, can enhance the perceived loudness because low-frequency sounds are more physically felt and have a greater impact on our perception of volume.

What are the disadvantages of a subwoofer?

A subwoofer is generally going to drain more power from your system than a normal woofer. That’s because low frequencies take the most power to produce. So, a subwoofer needs to work harder, meaning it needs to draw more power. Woofers, on the other hand, will generally require less power.

Size and Space Requirements: Subwoofers, especially larger ones, require significant space in your car or home. This can be a limitation, particularly in compact cars or small living spaces. Finding an appropriate location for a subwoofer can be a challenge.

Cost: High-quality subwoofers and amplifiers can be relatively expensive, and the cost doesn’t end there. You may also need to invest in additional accessories, such as wiring, soundproofing materials, and professional installation services, which can add to the overall expense.

Power Consumption: Subwoofers, especially powerful ones, can consume a significant amount of electrical power. This might lead to increased energy bills in the case of home theater setups, and it could potentially strain your car’s electrical system, affecting fuel efficiency.

Installation and Setup Complexity: Properly installing and configuring a subwoofer can be complex. Incorrect installation or tuning can result in poor sound quality, distortion, or even damage to the subwoofer or other audio components.

Why should I use subwoofer?

For starters, it can help you get a more even bass-response in the room, with less distortion and more dynamic headroom, making for more precision. In principle, using multiple subwoofers has the same positive effect of using one subwoofer. It’s just even more of the good stuff. Sometimes more is just… more.

Enhanced Bass Response: Subwoofers are specifically designed to reproduce low-frequency sounds, commonly known as bass. They excel at delivering deep, powerful bass notes that regular speakers cannot reproduce accurately. This adds a new dimension to music and movie soundtracks, making the audio experience more immersive and enjoyable.

Balanced Sound: Subwoofers work in tandem with your main speakers (satellites) by handling the demanding low-frequency sounds. This division of labor allows your main speakers to focus on mid-range and high-frequency sounds, resulting in a more balanced and clear soundstage.

Feel the Music: Subwoofers provide a tactile element to your audio experience. You not only hear the bass but also feel it as vibrations, adding a physical dimension to the music that can be quite thrilling.

Is subwoofer necessary for car?

Do I need a subwoofer in my car? Subwoofers are not a necessity in a car, but they can certainly enhance your listening experience. If you enjoy listening to music with a lot of bass, then a subwoofer can really help to bring out those low frequencies.

Audio Quality Preferences: If you’re a music enthusiast who values high-quality audio and enjoys listening to music genres that rely on deep and powerful bass, such as hip-hop, electronic, or rock, a subwoofer can significantly improve your listening experience. It enhances the bass response and adds depth to the music.

Cinematic Experience: In a car audio system used for watching movies or enjoying audio from video content, a subwoofer can make a notable difference in reproducing the low-frequency effects and soundtrack elements, providing a more immersive cinematic experience.

Sound System Goals: If you aim to create a well-balanced and dynamic audio system in your car, a subwoofer can complement the main speakers by handling low-frequency sounds. This balance improves the overall audio quality.

Which is more powerful woofer or subwoofer?

Get a subwoofer if you need something with great power and deep bass. If all you care about is high-quality sound without too much emphasis on those low frequencies, go for woofers instead! Having both dramatically improves the quality of the music you hear, and we recommend it.


  • Woofers are speakers that are designed to handle mid-range frequencies, typically ranging from around 40 Hz to 2,000 Hz.
  • They are commonly found in full-range speakers, including car door speakers and home audio bookshelf speakers.
  • Woofers are responsible for reproducing mid-range sounds, such as vocals and instruments like guitars and pianos.
  • The power handling and size of a woofer can vary widely depending on the specific speaker and application.


  • Subwoofers are specialized speakers designed to handle low-frequency sounds, specifically the deep bass frequencies below 200 Hz (often as low as 20 Hz).
  • They are dedicated to reproducing the lowest and most powerful bass notes in music and movie soundtracks.
  • Subwoofers are typically larger in size and have larger diaphragms (cones) compared to woofers, which allows them to move more air and produce deeper bass.
  • Subwoofers often require a separate amplifier or are powered by an external amplifier with substantial power output.

Do all car subwoofers need an amp?

Powering a subwoofer — Subwoofers require much more power than the typical speakers in a vehicle. A separate amp (or amp channel) is necessary when adding a subwoofer to any audio system.

Powered Subwoofers: Some car subwoofers come with built-in amplifiers and are referred to as “powered” or “active” subwoofers. These subwoofers have an amplifier integrated into their design, which means you don’t need an external amplifier to drive them. Powered subwoofers are often a convenient choice, especially if you have limited space or want a simpler installation.

Passive Subwoofers: Most subwoofers, however, are “passive” or “unpowered,” which means they do not have a built-in amplifier. These subwoofers rely on an external amplifier to provide the necessary power to produce sound. If you have a passive subwoofer, you will need a separate amplifier to use it effectively.

Power Handling: The power handling capacity of a subwoofer is an important factor to consider. Subwoofers typically have a specified power handling range (e.g., 100 watts RMS to 500 watts RMS). To get the best performance and avoid damaging the subwoofer, you should match it with an amplifier that can provide the appropriate amount of power within this range.

Where do you put a subwoofer in a car?

Under the Front seat

This is, according to us, the best place to put a subwoofer in a car. For this, of course, you will need two subwoofers placed under the driver seat and the co-driver’s seat.

Trunk: Placing the subwoofer in the trunk of your car is one of the most popular and practical locations. It provides ample space for larger subwoofers, and the trunk can act as an enclosure to enhance bass response. Ensure that the subwoofer is securely mounted to prevent it from moving around while driving.

Rear Seat: If you have a sedan or a car with a rear seat, you can install the subwoofer behind the rear seat. This location allows for a hidden and space-saving setup. However, it may require a custom enclosure or installation to fit properly.

Hatchback or SUV Cargo Area: If you drive a hatchback, SUV, or crossover vehicle, the cargo area can be an ideal location for a subwoofer. You can place it in the rear cargo space, taking advantage of the available room. Consider securing the subwoofer to prevent it from shifting during driving.
