Best Car Equalizer 2019 and Updated Buying Guide
Have you been wondering why your old car stereo is not satisfying your needs?
You might have selected the right head unit, installed great aftermarket speakers and even coupled them with an amplifier. There are particular sound factors that even the best speakers and amps cannot handle, the reason you are still receiving mediocre sound from your car audio system. Audio delivery may be affected by the absorbent nature of your car seats, glass reflectivity, the engine, noises from your car’s interior, and so on. These factors can affect sound frequencies such that some frequencies sound sharper and others muffled.
The ultimate solution for smoothing out frequencies is installing an equalizer, or EQ. An EQ balances audio frequencies between and within electronic signals. In other words, an equalizer enhances frequencies that need to be boosted and cuts those that the car or its sound system is exaggerating. Also, it compensates for the frequencies that a car’s interior distracts so that you get the best sound quality possible.

How to Choose the Best Car Equalizer
You want a car equalizer that gives you the best value for its price. The value of an EQ is reflected in the overall improvement it causes in your audio system. There are several vital features one should evaluate, as well as factors to consider so that the EQ achieves the required improvement in audio performance.
Before we look at factors to consider, it is important to understand the function of a car equalizer. A car EQ does not make car audio louder. Nor does it amplify speakers’ power. Rather, it smoothens out the frequencies of the sound system you have already installed in your car.
When it comes to the actual selection of equalizers, there are key considerations to make. These are explained briefly below:
i. Type of car equalizer
Car equalizers are of two main types: parametric equalizers and graphic equalizers.
A parametric EQ gives you higher sound control. They are designed to allow you control over the boost, bandwidth, and center frequencies.
On the other hand, graphic equalizers have graphic displays of different frequency bands for precise tuning. They have audio filters for specific frequency bandwidths of the audio spectrum. Most graphic EQs come with sliders which you can move up or down to adjust sound accordingly.
The type of equalizer you prefer depends on your experience with equalizers. It’s noteworthy that graphic equalizers are generally easier to use than parametric EQs.
ii. Number of bands
The number of bands implies how many sliders an EQ has. A 4-band EQ has 4 sliders. Correspondingly, a 7-band EQ has 7 sliders. The more the sliders the more control you have over the audio frequencies.
iii. Mounting location
There are different places you can place your car EQ. It’s inherent that you choose an EQ that’s suitable for installation in the spaces available in your car. Some dash-mounted EQs can be installed above or below the receiver. Others can fit below the dash using a special kit or a bracket. Truck-mounted EQs work with remote controls so that you can make sound adjustments from the driver’s seat.
Filters located on the front and rear channels are useful when using sub output. These filters allow certain frequencies to pass through them. The filter allows high frequencies to go to small speakers and low frequencies to subwoofers. The use of filters makes sure that the speakers and the sub are not forced to recreate sounds that they weren’t created to reproduce. Consider EQs with filters as they enable the system to produce higher quality sound.
v. Audio controls
Different EQs come with different controls for master volume, fader, sub volume, main or AUX inputs, etc. Inspect these controls, aiming to take home an EQ that gives you as much control over the sound as possible.
We have added a few additional useful tips to help you get the best out of the car equalizer you choose.
With an understanding of the critical factors to consider when choosing a car EQ, you can go ahead and evaluate each of the EQs we have included in this best car equalizers review.
