A graphic equalizer, also known as a peaking equalizer or tone control, is an audio filter used to modify the frequency response of audio signals. It is used in speaker monitoring and home stereo systems to adjust the frequency response of individual frequencies. A car audio system has different kinds of speakers that are capable of reproducing various sound frequencies -- from bass, midrange, high-end tweeters, and so on.

Using a car graphic equalizer, you can customize your listening experience by adjusting these different frequencies to create a more balanced sound. A graphic equalizer has multiple slider controls that look like a graph; hence the name “graphic” equalizer. These sliders control different frequency bands and allow you to boost or cut volume according to your preference.

We believe we will help you choose the best car graphic equalizer, especially with our Clarion EQS755 7-Band Car Audio Graphic Equalizer and Rockville R7EQ 1/2 Din 7 Band Car Audio Equalizer that will make you satisfied.

What to Look For in a car audio graphic equalizer?

Actually, when you decide to invest in car audio graphic equalizer for yourself, lots of things to consider! It's harder to choose since the product comes with many types, functions, and features from different manufacturers. That’s why you should find a reliable space to acquire knowledge related to the item. 

We’ve highlighted the essential features of the car audio graphic equalizer below. Along with checking out the list of best models in the list, you should also carefully read the buying guide here:

Parametric Equalizers

These equalizers are a step beyond the more standard graphic equalizers. They allow for more adjustment in terms of bandwidth control and primary frequency.


These controls control lower and higher frequency that could disrupt music. You can reach more frequencies if the decibel range is larger.


Some frequency ranges can be amplified, passed or reduced by audio filters. This is done by using a frequency-dependent amplifier circuit. An audio equalizer can adjust your music and remove or modify certain sounds with the filters.

Adjustment Range

Decibels are often used to measure ranges. The higher the range, the greater the ability to reduce or increase certain ranges.

Spectrum Analyzer

They are used on higher-end equipment as they provide real-time measurement of the audio signal. These allow you to see the frequencies of your frequency.


You can achieve finer control with more bands. Every band corresponds to a specific frequency, however, it is important that you know which frequencies each one represents, since it may vary depending on your equalizer. The definition of a middle-range in an equalizer may differ from the one used by another.

Bipolar Switching

The unique system uses twice the number of quadrants than traditional systems to increase voltage output.

Sound Processors

The equalizer also has a higher end part that adjusts its settings based on noise in your car.


What Is My Budget?

Graphic equalizers are available for purchase from $50 to $25,000, depending on the number of channels and features included. The price of graphic equalizers will rise significantly if you require more channels than 8. You will also need to have the ability to adjust all your parameters (high pass, low pass, volume, etc.) using your console without having to move faders. Expect to spend between $200 and $25,000

Should I Use The Presets?

Presets are great for novice users. The presets allow you to choose between rock and metal as well as any other musical style. These are not meant to be used for guidance when first using an equalizer.

What Is Equalization?

Equalization, from a musical perspective, is the act of changing the frequencies and sounds of a song. You've likely heard most of these frequencies at one time or another. Sound frequencies can be described as terms such as bass and treble. There are many instruments that can be found in any musical composition. The music might sound fantastic to the casual listener, but it could sound off for professionals. Audio equalizers are used to remove or filter certain frequencies in order to create a perfect harmony.

Do I Need To Equalize With Expensive Speakers?

You don't have to buy the most expensive speakers to use your audio equalizer. You can get just as much value from middle-range speakers as you will with high-end ones. Be careful with equalizing. If you aren't careful, your equalizer could cause damage to your speakers. You could damage your speakers if you have accidentally set the output level to the wrong place. You can check for damage by playing the sound through your speakers at a higher volume. The speaker may be damaged if the volume is too low. Modern speakers are capable of handling short-term distortion. Listen carefully.

What Is The Physical Size Of The EQs?

Although this may sound obvious, I have seen many people make the same mistake. If you have a rack case or console, make sure it has sufficient space for the new EQs. Make sure you measure the equipment before buying. Then compare the measurements to your rack/console. Engineers these days are working on a tight budget and needing minimal equipment so any additional weight or size can be problematic.

Will This EQ Be Rack-mounted Or Used On A Console

You can buy all of the PMQs listed above in rack-mountable 1U or 2U models. You can purchase multiple units of this type at one time, but it will cost more. However, you could order a customized-fitted box and put them all together. There are two types of MBCs: analog or digital. Make sure that your console can support an analog model. Although not essential, it is best to purchase equipment that works well together.

Do I Need An Audio Equalizer?

It's a difficult question that will be influenced by how obsessed you are about music. While the average person won't think about equalizing music, audiophiles may. A newbie should take it slow, particularly if creating or recording music or mixing songs. A slight tweak can make a huge difference in the sound and it may not be for the best.

After knowing the suitable kinds of car audio graphic equalizer and the features you wish, it’s high time for you to start your shopping. Note that you shouldn’t run out to a particular store or start scrolling through online sales just yet. With the development of technology, especially the expansion of sale sites, you can easily find your buddy.
