Best Car Subwoofer

Many people simply can’t imagine driving without a pleasant music with high-quality sound. Any music consists of a whole range of frequencies (sounds), the reproduction of which helps us to enjoy the listening. By removing some of those sounds, we won’t be able to fully enjoy our favorite music. Low frequencies play a very important role in the sound quality. For example, percussion instruments and bass guitar are the basis of the music of most songs, because they set the rhythm. And the rhythm is fundamental. If you are determined to achieve the best sound in the car, you can’t do without a subwoofer. The subwoofer delivers a deep, loud bass, at the same time making the acoustic design of the car complete and flawless.

We recommend looking at these main criteria

Audio Quality
The sound quality doesn’t depend on the number of speakers in a car. If you use mediocre quality equipment, you could get the opposite effect – all the noise and rattles will sound simultaneously from all the speakers. In most cases, for a strong and beautiful sound, it’s enough to have a powerful subwoofer and a good amplifier.

In order to determine the really worthwhile equipment, it is necessary to investigate the general composition of the background music and the influence of sound components on each other. Usually, several records of different styles are selected to fully test the equipment. That is, the high-quality sound makes it possible to hear all the nuances of music, both individually and in a single sound.

Power Handling Performance
When reading the characteristics of the subs, you should pay attention to the RMS power. This is exactly the index at which the sound will go without any distortion. Usually, the power of 150-300W is enough for a car, but if you want to feel the bass with all your body, go for 300-600W.

If you want to achieve the high-quality sound, then the power handling performance of the subwoofer should be no less than the total power of all acoustics in the car. For example, if you have four speakers of 60W. Their total power will be 240W. So, to create a quality sound, the sub power handling of 240W will be enough. You can also buy a sub with a margin of 10-20%. This power handling performance of the subwoofer will suffice for the normal sound of the audio system.

Enclosure Specifications
As for the subwoofer enclosure, there are several options:

  • Closed – this is a type of subwoofer, in which the cabinet has no holes. This option is most popular due to the optimal ratio of price and sound quality.
  • Vented (box with bass reflex) – a subwoofer is made in the form of a tube with a hole. It features a deep and loud bass. It costs more than the closed one, but the sound is also much better. The downside is that this form does not always fit well into the trunk space of the car.
  • RadPass – a subwoofer that includes two low-frequency drivers, each of which operates at its own frequency. The additional driver serves to lower the overall resonant frequency of the loudspeaker. This option is very expensive, and it is quite rare for ordinary cars. As a rule, it is used for expensive cars or those that participate in auto sound competitions.
  • Compact-Sub (compact subwoofer) – a low price subwoofer of medium size. It is easy to install and does not stand out with an extremely high-quality sound. Commonly, car subwoofers of this type are located in the passenger seat area.
  • BandPass – a subwoofer of this type provides the location of the woofer inside the case, while the sound goes out through the bass reflex. This option is not cheap, but beneficial because it allows connecting a sub without a crossover.

Recently, super-compact flat subwoofers, which are designed for installation under the seat, have become popular. Their main advantage is that they can easily be installed under the driver or passenger seat, screwed on the rear shelf or to the back of the seat in the trunk. They almost do not take up space. But not all subwoofers need a cabinet. There are so-called Free Air models. For such driver, it is enough to simply cut out a hole in the rear shelf of the car and install it there. The high price and complexity of installation make free-air subwoofers not in demand in the world.

The other quality parameters are the size and number of voice coils. Many people think that the larger size is the better, but this opinion is not true. Larger dimensions will make more noise. A huge woofer can simply “shake” the car and kill all the sounds. Too small sub may not give the necessary result due to noises that are caused by the road when driving. Therefore, we recommend buying subwoofers with the driver dimensions of 10-12 inches. This will help to get a good quality bass and more options for placement in the car.

As for the number voice coils, usually, the single-coil is enough. But if the probability of future experiments with an audio system (changing the overall configuration or its components) is not excluded, then it will be better to use a subwoofer with dual voice coils. Their huge popularity is explained by the flexibility in connection. The installation of two coils in one sub is one of the constructive methods of the manufacturers, which is used to increase the power handling performance. Naturally, the introduction of an additional voice coil leads to a rise in the cost of the subwoofer.

We suggest looking at the rating of three best subwoofer models in 2017 and compare their characteristics.

  • Audio Quality Score

We determined a score to quantify the overall sound quality of each subwoofer. For our comparison, we compared 12-inch subwoofers because this is the most common size.

  • Lowest Frequency Response (Hz)

The lowest frequency produced by the speaker’s woofer. These frequencies account for the bass notes.

  • Highest Frequency Response (Hz)

The highest frequencies produced by the subwoofer. The highest frequency response should crossover with your car speakers’ lowest frequency response.

The passive subwoofer Pioneer TS-W3003D4 belongs to the professional model range of Champion systems. With the 12-inch driver, it provides a flawless reproduction of bass sounds with a frequency range of 20-80Hz. The peak power of TS-W3003D4 is 2000W, and 600W is stated for the RMS power. The use of a special suspension device Air Suspension System determines the peculiarity of the internal design of the subwoofer. It creates an airless diffusion zone. Due to this, the main diffuser moves smoothly and this creates the conditions for deep bass.
For making extremely hard and resilient diffuser the manufacturers used a top quality composite material based on carbon and basalt fibers. The low weight of 18.4 pounds allows the subwoofer to create a powerful bass sound with virtually no dissonance distortion at maximum volume.

  • High RMS and peak power performance
  • You can choose different amplifiers
  • Diffuser made of carbon and basalt fibers
  • Requires an amplifier to be bought additionally

  • Sensitivity (dB)

A measurement for how efficient the speaker is able to convert wattage to sound. Sensitivity ratings indicate the decibel levels measured at one meter from a speaker using one watt of power. A higher decibel sensitivity rating means that the speaker is louder with less power. For example, if an 88dB speaker needs 100 watts to produce a specific volume, then a speaker with 91dB speaker would only need 50 watts to produce the same volume.

  • Continuous Power Handling (RMS Watts)

The speaker’s optimal wattage for continuous use. Exceeding this for long periods at a time can cause damage to the speaker.

  • Peak Power Handling (Watts)

The maximum amount of wattage that the speaker can handle in short bursts before damaging the speaker.

  • Impedance (Ohms)

A measurement of electrical resistance. When purchasing speakers, it is important to make sure that the impedance conforms to the amplifier you use.

Kicker 40CWRT122 belongs to the CompRT ™ series, which is the flattest of all the released series in the world of powerful bass. A small installation depth allows you to install it in the narrowest places. And that’s the main advantage, 40CWRT122 gives out deep bass and could be installed in places not enough for subwoofers of the usual size.

Despite the small installation depth, this subwoofer comes with dual voice coil and 2-Ohm impedance. The peak power reaches 1000W, while the RMS power is also quite high and equals to 500W. This model uses a centering shim of large diameter with progressive characteristics to increase the linearity of the stroke and reduce distortion. Kicker 40CWRT122 has a die-cast polypropylene diffuser and a solid Santoprene ™ pendant.

  • Possibility to install in the trickiest places
  • Reasonable price
  • Two pairs of strong clips
  • Dual voice coil
  • Power handling is not rated correctly

  • Fs Resonant Frequency (Hz)

The frequency at which the subwoofer naturally resonates with the air. The Fs is important for installation and tuning of the enclosure box.

  • Mounting Depth (Inches)

The depth required for the subwoofer to be mounted in an enclosure.

  • Ideal Sealed Box Volume (Cubic Feet)

The ideal size needed to install a 12-inch subwoofer with a sealed enclosure box. Sealed enclosures are smaller and produce a tighter bass sound than a ported enclosure because the sealed air moderates the cone’s motion. This style is ideal if you want to hear accurate and balanced bass.

  • Ideal Ported Box Volume (Cubic Feet)

The ideal size needed to install a 12-inch subwoofer in a ported enclosure. Ported enclosures have holes in the box that allow air to move in and out. Ported enclosures produce booming bass because the port allows the woofer to move freely. Ported enclosures are ideal if you like your bass to sound big and punchy and you don’t mind some distortion.

  • Dual Voice Coil

The voice coil is the magnetic component that moves the speaker cone. Two of these adds flexibility to a subwoofer and provides multiple wiring options.

Polk Audio DXi124 subwoofer of the DVC series can boast of only the best technologies, moderate cost, and excellent characteristics that will certainly please fans of unsurpassed sound quality. DXi124 DVC has a large diffuser with a diameter of 12-inch. Such size of the subwoofer is optimal for installation in any large-sized cars. The RMS power equals to 360W, while at peak capacity this number can reach 720W. Dual voice coil and a nominal impedance of 4 Ohm ensure the reliable operation of the DXi124 subwoofer at high power. Thus, it provides the reproduction of deep and juicy bass that you will not only hear but also feel with your whole body. Polypropylene diffuser with a rigid dust cover made of ABS plastic provides increased mechanical strength and helps reduce distortion.

  • Extremely low distortion
  • Excellent sound quality
  • Clever design
  • 4 Ohm impendence instead of stated 8 Ohm


When choosing subwoofer for car, it is important to understand that no one can guarantee the perfect sound in your car and its sound system, even a car audio seller with more than ten years of experience. There are a lot of various nuances in this sector. Protection Status
