Buying Guide To Choose The Best Car Equalizers

The car equalizers are of two main types (parametric and graphic equalizers) and come with a variety of features like subwoofer controls, crossover circuits, and time alignment to achieve the best sound quality in the car.

Selecting the right equalizer for your car audio system based on several factors, including audio preferences, features, and compatibility is a bit difficult task. Here are some of the best features that help you to make the best buying decision.

Let’s dive into its details…

1. Type of Equalizer

Car equalizers are of two types – parametric equalizers and graphic equalizers. You have to decide the type based on the kind of sound/audio preference you need to achieve. A parametric equalizer is suitable for people who prefer customized audio tuning of each frequency band, which means you can fine-tune every little detail in the tone. While, on the other hand, a graphic equalizer is ideal for people who prefer preset audio tuning, which means you can either cut down the particular frequency or boost it in the mix.

2. Compatibility

The equalizer you want to purchase has to be compatible with the audio system of your car. For this, you need to check whether or not the equalizer is compatible with the head unit, speakers, and amplifier without any unnecessary wiring or connectors.

3. Number of Bands

The number of bands in the car equalizer is the way to adjust the frequencies range. An equalizer with higher bands will allow for precise adjustments. So, prefer to select the car equalizer with a minimum of 4 – 10 bands for the finest sound quality. However, equalizers with 7 or more bands are the most preferred options for car audio systems.

4. Build Quality

A car equalizer made of high-quality materials and components is always the preferred option. So, look for a well-constructed equalizer that will deliver better sound quality and last longer.

5. Signal-To-Noise Ratio

The signal-to-noise ratio (SNR) measures the audio signal quality produced by the equalizer. Prefer to look for an equalizer with a high SNR (above 90 dB) to enjoy the best audio quality.

6. Easy Installation & Mounting

An easy-to-install car equalizer is the most preferred option rather than one with a complicated installation or setup process. So, choose the equalizer that comes with clear instructions and is compatible with the car wiring system as well.

The dash-mounted equalizer is installed on the below or top of your receiver. Equalizers are available with different mounts, which means you need to check the available installation space in the vehicle along with the proper fitting of the equalizer before making its purchase. Otherwise, you need to buy the mounting brackets and other hardware material for its proper installation & usage.

7. Brand Reputation

Ensure to look for the brand that offers the best reputation for producing high-quality car audio equipment. Select the equalizer from a well-known brand having a proven track record of manufacturing durable and reliable car equalizers for their longevity and enduring performance.

8. Controls

EQs offer a wide range of controls like volume, faders, Auxiliary inputs, and others to improve the user’s ability to fine-tune the sound quality and thereby produce better audio. So, an equalizer with more added controls will enhance the ability to fine-tune and customize the sound quality for an excellent audio experience.

9. Filters

Some EQs come with filters or crossovers used to separate high, medium, and low frequencies and then set them properly to the correct sound driver in the speaker for exceptional audio. This means the high frequencies of the audio signals are sent to the tweeter & super tweeter, mid-frequencies to the mid-range driver, and the low frequencies to the woofer.

10. Price

The price of the car equalizer is another deciding factor for most users, in which the price will range from $25 to $300. All you need is to consider the required features and the budget range and then select the model that comes within the budget range and offers the required features to enjoy high-quality audio.

11. Extra Features

There are some additional features, including built-in crossovers, subwoofer controls, and Bluetooth connectivity that allows for optimal audio quality. So, check for these extra features whichever you need for exceptional sound quality.

12. Read User Reviews

The user reviews will help you get a clear idea of the audio quality, ease of installation, and overall satisfaction with the product. So, it is a must to look and read their valuable insights into the performance and reliability of the product. Also, it is advisable to check the warranty period offered by the manufacturer on its products for durability, longevity, and reliability.


All these factors will help you in selecting the best car equalizer that meets your audio requirements along with providing optimal sound quality in the car.

Best Equalizers for the Car – FAQs

1. What is the minimum EQ to improve the sound?

Ans: The car equalizer with a minimum of 40 Hz will enhance the sound quality. Choose and set the equalizer with the apt range to improve the overall sound quality for an exceptional audio experience.

2. What EQ will provide the best bass or make the music louder?

Ans: If you want to maximize the bass-heavy music, you need to adjust the equalizer for bass frequencies that have a low range from 20 Hz to 400 Hz. Setting the equalizer within this range will help you to get the best bass. If you are looking for louder and clearer music, then prefer to go with the equalizer offering the frequency response of 20 Hz to 20 kHz.

3. What’s the difference between a crossover and an equalizer?

Ans: Both (crossover & equalizer) are two advanced-level car audio components that are used for processing the sound. The equalizers are used to adjust the audio signal and enhance the sound frequencies in the music. Whereas, the crossovers are used to control the sound sent to one or more amplifiers depending on the speakers, and also allow for 2-way or 3-way component speaker systems. Simply, EQ customizes (cuts or boosts) the frequency output of the audio system while crossover blocks some frequencies from the audio signal and sends the remaining to the relevant speaker.

4. Is an amplifier required to use an equalizer?

Ans: In general, an amplifier is not required to use an equalizer. In most cases, the car receivers have a built-in amplifier that has to add an equalizer to work with the unit instead. If not, you need to set an amplifier for the proper functioning of the equalizer.

5. Are equalizers worth it (or) do I install them by myself?

Ans: If you want to have complete control over the sound and bass quality on different frequencies, then an equalizer is a must to purchase and set in your car.
If you have some knowledge of the car audio system and its installation steps, then you can install an equalizer in the car/vehicle all by yourself. If you don’t know how to install it, then take some professional assistance for the proper installation of an equalizer in your car.


To conclude, equalizers (EQ) are used to shape the sound coming out of the stereo system. They let you fine-tune the audio (bass, midrange, or treble) to produce high-quality sound output by selecting the required frequencies.

Here are the quick recommendations that help you to pick the car equalizer instantly based on your requirement.
