Best Equalizer Settings for Car Audio – The Ultimate Guide

The best equalizer settings for car audio are a balancing act. You want to make sure that you have good bass, without having it distort at high volumes. You also want to make sure that your mid and treble frequencies are set correctly so that your music sounds clear and crisp.

Most car sound system will have some kind of graphic equalizer (EQ) that you can use to adjust the sound frequencies. If your car stereo system does not have equalizer settings, you can usually find one in your audio settings menu. Once you open up your EQ settings, you will see a bunch of different frequencies that you can adjust.

The best equalizer settings for car audio bass, mid treble is by using a rule of thumb that is called the “Golden Ratio.” This ratio suggests that the bass, mid, and treble frequencies should be set at a ratio of 4:5. So, if you are adjusting your bass frequency, you would want to adjust it to 100 Hz. Then, you would adjust your mid-treble frequencies to 125 Hz and 250 Hz.

Of course, every car stereo is different, so you may have to play around with the EQ settings a bit to get it just right. And, don’t forget that you can always adjust the volume of each frequency as well! If you find that the bass frequencies are too overwhelming, you can always turn it down a bit.

In this blog post, we will discuss the best EQ settings for car bass, mid-treble, and everything in between!

What is an equalizer?

An equalizer is a special circuit that adjusts the level of low frequencies (bass), midrange, or high frequencies (treble).

It is a very useful device to have in a car to enhance the quality of your car audio systems.

Most cars come with equalizer settings that adjust the bass, mid, and treble (high) frequencies. Most modern cars also come with EQ presets such as jazz, rock, country, classical, pop and more.

However, if you want to make the most of your car’s bass, mid, and treble equalizer settings, it is important to understand what each frequency does and how to use them effectively.


Let’s start with the basics, and look at what frequencies are and why they need to be adjusted in your car audio system.

Frequencies are the units that the human ear hears. They are measured in hertz (Hz). A hertz is a measurement of cycles per second.

As an example, a song that plays at 150 hertz has 15,000 cycles per second.

Each frequency band (low, mid, or high) is separated by a number. For example, 50hz is half of 1,000hz. The higher the number, the higher the frequency.

In a car audio system, there are many different types of frequency bands.

Bass is the lowest frequency and mid is the mid-range frequency, while treble is the highest frequency. There is a separate frequency band for each of these.

Some equalizers have multiple equalizer frequency bands. The bass, mid, and treble equalizers typically have their own separate frequency bands. However, they may share some of the same frequency bands.

Here is a basic diagram of the different types of equalizer frequency bands.

How Do Equalizers Work?

To understand how equalizer settings work, you need to understand some basics about audio processing.

Equalization is the process of adjusting the volume of one part of a recorded audio signal relative to another part. Equalization changes the perceived frequency balance of the overall signal and makes audio files sound richer and more exciting to listeners.

Equalizers are often used by sound engineers, radio DJs, and music producers to fine-tuning an album to give it a more balanced, focused, and cohesive sound.

There are three basic types of equalization, based on how audio signals are processed:

The most common type of equalizer is a digital equalizer. This can be found on most car audio equalizers and allows the user to adjust the volume of the different parts of sound waves.

The second type is a parametric equalizer. This is similar to the digital equalizer, but instead of having only one slider, it has multiple sliders with varying frequencies. These allow the user to change the amount of emphasis on a specific part of sound waves.

A third type is a high-pass filter, which removes low-frequency content from a recording.

What are Bass, Mid, and Trebles?

Before we go further let’s first understand what is Bass, Mid, and Trebles.

Bass is producing low sound. We can adjust the bass frequencies from 20Hz to 20000Hz. The bass range is defined as the frequency at which a speaker or other sound transducer is capable of producing low sound (bass) frequency with sufficient volume, clarity, and quality for the listener to be able to adequately hear and understand it.

The mid-range, also known as the center frequency range, is the area of sound that is heard most clearly. The human ear is most sensitive to sounds in this range, so it’s important to get this frequency response just right. The mid-range sounds from 300 Hz to 3000 Hz.

Treble is a high-frequency sound. The hearing range of treble sounds is from 4000Hz to 20000Hz. Treble refers to the high-frequency sounds in music or other audio. These are the high notes that give the music its “great sound.”

Now that we know what these frequencies sound like, let’s talk about how to adjust them.

Equalizer Preset

There is no one perfect setting for the equalizer and most of the car stereo comes with default equalizer preset which are commonly known as Classic, Rock, Jazz, Hip-Hop, and so on. If you are not sure where to start, it is the best option, to begin with, one of these EQ presets and then make adjustments from there.

However, if you want more control over your desired sound, you can always choose the “custom” or “user” settings option. This will allow you to adjust each frequency individually.

Here are some steps recommended to get the best result:

Steps – Best equalizer settings for car audio bass, mid and treble

Step 1 – Start by finding the best equalizer settings for car audio bass, mid and treble. The bass should be set at a lower level to avoid distortion, while the mid-range frequencies and treble range can be increased to get the best sound quality.

Step 2 – Experiment with the different frequency bands to find the best settings for your car stereo system. You may need to adjust the levels several times before you find the perfect sound balance.

Step 3 – Balance the sound levels between the different speakers in your car to create an even soundstage. This will help you achieve the best possible audio quality no matter where you are sitting in the vehicle.

Step 4 – Adjust the volume and check if the quality of car sound is improved to ensure you’re getting the best possible results.

Step 5 – Once you’ve found the best equalizer settings, make sure to save them so you can easily revert back if needed. Equalizer settings can be different for each type of music, so it’s important to have a few different presets on hand.

By following these simple steps, you can greatly improve the sound quality of your car stereo system. With the right equalizer settings, you’ll be able to enjoy your favourite music or podcast with crystal-clear sound. Experiment until you find the best equalizer settings for car that work best for you.

Tips – Best equalizer settings for car audio bass, mid and treble

  • If your car has a subwoofer, make sure to adjust the levels accordingly. The bass should be turned up enough to provide a good low-end response, but not so high that it overpowers the other frequencies.
  • Listen to your music at different volumes to find the ideal listening level. You don’t want the bass boost or treble settings levels to be too loud or too soft, so adjust them as needed until you reach the balance settings.
  • Take advantage of any audio controls available in your car. Many newer vehicles have built-in equalizers that can be used to tweak the sound to your liking.
  • If you’re still not happy with the sound quality, consider upgrading your car speakers or head unit. Better-quality components will make a big difference in the overall sound of your car’s front and rear speakers.

Note: Before doing anything make sure you park your car in a safe place. It is not advisable to adjust your car’s audio system while driving. Adjusting your car’s audio system can be a dangerous task, especially if you’re not paying attention to what you’re doing and it causes you to lose control of your car.


The best way to get the most out of your car’s sound system is through experience and experimentation. If you’re not sure what frequency band should be set at a higher level, try listening to different types of music or podcasts on low volume with various adjustments until it sounds just right. Experimentation will allow you to find the perfect balance between bass, mids, and trebles that fits both your personal preferences as well as the acoustics of your vehicle. Don’t forget about other audio controls available in newer car models like built-in equalizers!


Why Is Tuning Your Stereo Important?

When you listen to music, you’re probably used to fine-tuning your stereo so that everything sounds just right. After all, a good stereo system can make any music sound great. So why is it important to tune your stereo?

Because a properly tuned stereo is easier to enjoy. Poorly tuned car stereos might even be painful to listen to. For instance, the front and rear speakers might not produce the correct volume, or the bass might be too loud. And while we often associate music with happy feelings, a well-tuned stereo can help you feel relaxed, calm, and content.

How to choose the best equalizer settings?

The frequency bands for your car audio system may be adjustable. If your car comes with EQ presets, you don’t need to adjust anything.

But if it doesn’t, then you will need to use the EQ adjustments to create your own custom settings.

You will want to experiment with the different sound settings until you find a sound that suits you.

Why are equalizers needed?

For years, we’ve been told that the best way to enjoy music is to listen to it in the exact same way as the artist intended.

But what if you want to hear something different? What if you want to change the sound of your music?

For instance, if you’re listening to a song and you notice that the vocals are overpowering the rest of the music, you could lower the volume of the vocals.

Or if you’re listening to a song and you notice that the guitar sounds a little weak, you could boost the guitar’s volume.

The point is that you can change the sound of your music without actually changing the music itself.

This is where equalizers come in.
