Automotive subwoofer: How to choose the best in 2022?

Thinking of increasing the quality or the sound power of your vehicle? So a great alternative could be the purchase of an automotive subwoofer. In this article, we will explain all the details about these products!

Subwoofers are just one type among many possible speakers. They have specific applications, mainly to reproduce lower sounds, at lower frequencies than other types of speakers.

To find out if this really is the kind of automotive speaker you need, stay with us! We will explain each detail for a perfect understanding of what a subwoofer is and show which models are most suitable.

First, the most important

  • Automotive subwoofers are used to improve the sound quality in a vehicle. They differ from other types of popular speakers, such as woofers and tweeters, in the sound frequency they produce.
  • Due to frequency and other important characteristics, subwoofers are more recommended for improving the internal sound of a car, not for parties or projections in large environments.
  • The values ​​of subwoofers can vary between R $ 100 and R $ 3,500, but most models between R $ 300 and R $ 400 are already of excellent quality.

Buying Guide

How to choose an automotive subwoofer? What are the most important technical criteria? How do you know that it will really make a difference in your vehicle?

Check now all the details so you can enjoy a high quality sound inside your car!

What is an automotive subwoofer and what is it for?

It is very common for people to want quality sound in their cars. Whether listening to music or radio during the daily commute, or having fun with friends in open places, this is a reality for many.

For this to be fully possible, it is necessary to buy good speakers. There are several types: subwoofers, woofers, squakers, tweetters, among others. But how do you know which is ideal?

Subwoofers are the speakers that reproduce the lowest frequencies, ranging from 20 to 200 Hz. This serves to reproduce the lowest sounds, giving a higher quality to the audio.

In addition to automotive use, speakers like this are essential in sound systems that are intended to achieve a high level of reproduction. In home theaters, for example, there will always be a subwoofer.



Did you know that the first subwoofers were developed in the late 1960s?

They were necessary because the evolution of sound for cinema and television began to allow the reproduction of very serious sounds that did not exist in these media before.

The 1974 film “Earthquake” (which won the Oscar for Best Sound) was one of the pioneers in introducing these lower frequencies. Without speakers capable of reproducing them, the sound industry worked on perfecting subwoofers.

What are the differences between subwoofers and other speakers?

The main difference between subwoofers and other speakers is in the sound frequency reproduced. The tweeters are the ones in the highest spectrum, reaching up to 20 thousand hz. They are special for high-pitched sounds.

In the middle layer are the woofers, capable of reproducing frequencies between 80 and 400 Hz. Medium-low are the sounds that find the best reproduction with them. At the other extreme, there are precisely the subwoofers.

Subwoofers, in order to reproduce such serious sounds, must have special designs and taller and heavier cones. Physically, they are likely to be larger in height, but smaller in width.

But which one is right for your car? Well, it depends on what you want to have in your sound system!


Very low sound travels shorter distances. Quality is likely to be improved, with better recognition of instruments. However, the further away from the vehicle, the more that quality will be dissipated.

Thus, subwoofers are recommended in two situations: if you want a high quality sound system for the inside of the car, that is, to listen while driving, or if you want a more visceral experience, with a shaky floor , in external situations.

If the desire is for an external sound of greater power, but still well defined, for parties and meetings with friends, the ideal is to have a woofer. We exemplify all of this in the table What should be the size of the automotive subwoofer?

Be sure to pay attention to the size of the automotive subwoofer: very common numbers to be found are 8, 10, 12, 15 and 18 inches. This will have a great influence on the sound produced.

The larger a subwoofer, the more it moves air in a movement that generates a sound wave. Thus, it will have a lower frequency and reach lower sounds.

In other words, an 18-inch subwoofer requires much more internal space in your vehicle, but it produces a much higher quality sound. For a good internal sound, the 8 would be ideal, but the higher, the more perfect the bass will be.

How much?

Automotive subwoofers vary in price according to their size, material and power supported. The cheapest ones cost approximately R $ 100, but they are not usually the most powerful.

To get a product of the highest quality that the market offers, it will probably be necessary to pay between R $ 300 and R $ 400. However, there are some models that can cost up to R $ 3,500.

It is worth mentioning that these models that are so much more expensive tend to be the so-called “active subwoofers”. They need their own power supply, unlike the others, but they produce a much more accurate sound.

“The real beauty of music is that it connects people. It carries a message and we, the musicians, are the messengers.”

Where to buy?

There are stores specializing in automotive sound. In them, you will find a high level of service, coming from people who work daily with the subject and understand everything that is necessary.

If your preference is an internet purchase, Amazon has a large number of models. Other famous e-commerces, Amazon international also bring a satisfactory range of options.


Purchasing criteria: Important factors in evaluating an automotive subwoofer

In addition to everything we’ve already explained, there are a few more important factors to note before buying an automotive subwoofer. We list some of them below:

  • Wattage
  • Impedance
  • Material and design
  • Sensitivity

Curious? Then we will explain below what each of these points means!


Do not confuse power with pitch or sound range. What this number actually means is the charge it can receive from an amplifier or player without burning.

The number of power is agreed to be measured in RMS. The ideal is never to use a product with less power than the amplifier. This will cause serious damage to your sound system and a lot of headaches.


Technically speaking, impedance is the resistance of a speaker’s coils to the passage of electrical energy. This number, measured in ohms, is related to the power and the reproduced frequency.

In subwoofers, impedances of 1, 2, 4 and up to 8 ohms can be found. For day-to-day use, there is hardly any perception of difference between one and the other. If the intention is for external use, a higher impedance is already recommended.

Material and design

There are two reasons why material and design are important: the first and most obvious is the visual factor. A model may be more beautiful for some, not so much for others. If this is a key feature for you, choose calmly.

Another factor is that, in subwoofers, the cone usually needs to be thicker and heavier than in woofers or tweeters. This requires more resistant materials such as polypropylene, graphite and titanium.


The sensitivity, together with the size, directly influences the audio quality. The larger it is, the greater the power required to generate more serious waves, thus reaching the full potential of the model.

In some ads, this number is highlighted, in others, it is not. Sensitivity is a field in which, if it is in your interest to evaluate at the time of purchase, the help of a specialist will be essential.
