What is an Equalizer or EQ? 

Before jumping on “how to adjust the car equalizer”, we’ve to understand what the heck is “Equalizer”? Well, as the name suggests, an equalizer is a device that helps you hold the control of some adjustments. In-car stereo, serves as an audio filter that catches and separates specific frequencies and alters them according to the adjustments made.  

How does an Equalizer work? 

With the help of an equalizer, you can adjust the low and high ranges, whether it is an EQ embedded in the car stereo or the one that works at your home – the function is the same for all. 

Every car model is equipped with a dual-band equalizer, which means the driver can easily cut off enhancing any bass. An EQ works in the band of the ranges. This dual-band can also be referred to as “band” and “treble”. 

But many advanced cars with the magnificent stereo system may come with the three, five, twelve, twenty, or even thirty bands depending on the car’s model, and for that many bands, the hearing also gets a wide range. 

Each band can control a certain frequency and you have to be certain about which one is the right fit for your eardrums. 

However, the system working in the equalizer is complicated but thanks to the graphics that made it easier for the drivers to adjust the settings by moving up and down the knobs, it’s done.

Bass Mids and Treble – what are these? 

In general, the voice of the human is considered to be the mid-range but being more specific in this, the mid-range frequencies range from 28Hz to 3900Hz, which is the same as the standard piano frequencies. 

There are ten audio frequencies ranging from low to high in the car stereo, so we can easily differentiate between each. 

  • 40Hz
  • 80Hz
  • 160Hz
  • 320Hz
  • 640Hz
  • 1280Hz
  • 2560Hz
  • 5120Hz
  • 10,240Hz
  • 20,480Hz

Let’s classify the ranges of the frequencies in following: 

  1. 20-80Hz is considered as the Low-Bass.
  2. 80-320 Hz is considered as the “Mid-bass”. 
  3. 320-1280Hz is considered as the “Mid-range”.
  4. 1280-5120Hz is considered as the High Mid-range
  5. 5120-20,480Hz is considered as the High-Treble. 

Bass describes the low tones, it essentially refers to the low frequencies and pitches. 

Most drivers prefer to make sound adjustments in the mid-range. Mid-range frequencies are the natural ones, not too fast and dull. 

They cover the excellent details so precisely without even making the tone too bright.  

Treble is the category of the sound frequency higher than the level of human hearing, such as flute tunes. It is exactly opposite to the bass frequencies.

It must have the cymbals, flutes, and brass that make high notes, vocal, piano, and guitar that sit on the mid-range, and drums and bass to create low notes. 

In short, pick the song that makes the whole of it, it has to make the variable notes with different frequencies. 

Step: 03 Tuning the Fade Control for the Speakers and Eliminating Noise

First, you will need to control the car fade control. Make some adjustments until you eliminate the fade property and feel the music is coming right from the speaker in front of you. Record the adjustments.

Once you eliminate the fade and listen to the speaker’s type of audio. Go for the fade setting again and adjust it the way that the sound is coming from the rear speakers. Note the reading and feel the difference in both cases. 

The settings for both the front and back speakers have to be the same. Mostly, the speakers come with the same settings, but if they are different, you’ll have to get some minutes and make the right adjustments with the speakers until you pull off the right balance. 

You have two speakers, and their adjustments can be done via the head unit. . It enables tone control. The rare speaker needs to have a lower treble than the front one. Make the setting in your head unit because it will help you achieve the sound as if it is coming from the front speaker no matter how low or high the volume is. 

You have to play around with the adjustment in your head unit so that you reach that desired point where the noise could also be eliminated precisely. 

If not, you may have tweeters at some different locations in the car, you need to focus on the rare speaker – set the frequency again and try, while subwoofers can also be the best match when introduced along with the speakers. 

This is all the settings done here for the speakers, the next part is to set the tone of an Equalizer.

Listen to the music you’ve made adjustments for with the speaker, a little tuning might require more than with your EQ. 

  • Play around with the frequency, and if you don’t get the desired settings, you can have an equalizer sound booster or a bass booster. 
  • High tones have to be nice to the ears and not piercing. 
  • You can try different EQ presets, bass, treble, and cuts unless the desired music settings are achieved. 

Step: 05 Test the Loudness and Bass with the Multi-level Song

All adjustments are made here, now you have to test the settings of an EQ with the multi-level song. The game is all about how the speakers run and the frequencies that your ears love to listen to.
