What is a Car Equalizer?

An equalizer controls the tones of your sound, up to and above what is found in most radio systems. This precision control allows for unique customization based on your needs and wants of your sound system.

Each system comes with a certain set of bands that allow you to control certain frequencies. These bands can be adjusted based on numerous different quantities and ranges. All these adjustments might seem a bit superfluous to you, but if you really want a killer sound system setup, a great equalizer can push you over the edge. Allowing you to tune to your tastes can give you a sound not heard before.

Physically these devices are made from a non-conductive metal and are flat and wide in appearance. The back has a series of inputs and outputs to connect to your audio equipment, while the front has different knobs that can control the frequency bands.

Equalizers can also have additional adjustments, lighting for the knobs, along with the ability to save certain adjustments for repeated use. These tastes can be tailored to overcompensate for certain noises intrinsic to cars such as wind, road, grills over the speakers, and so forth.

Equalizer Terms to Know

Best Car Equalizers: Review and Buying Guide (2018 Update)

To understand a bit more about car equalizers you need to know some of the lingoes. While not an exhaustive glossary of terms, knowing what some of these words mean will definitely give you a leg up when picking the equalizer that you want.

  • Analog: This type of equalizer uses physical mechanisms to work, such as sliders and knobs, to control the frequencies.
  • Articulation: The level of articulation is how intelligible each part of the sound, or frequency, is.
  • Bandwidth: High bandwidth translates to a higher range of notes that are affected by that specific control. Also called the Q.
  • Crossover: These filters isolate certain frequencies that are typically higher and lower on the spectrum to make your music sound less distorted.
  • Decibel (dB): This is a relative measure of sound, that increases exponentially. For example, 20dB is 10 times louder than 10dB, not twice. For an equalizer, decibels are used to show the relative loudness of one part of the frequency to another.
  • Digital: These types of equalizers use software to control frequencies.
  • Filter: This electronic circuit blocks certain signals while allowing others to pass. Filters are often described via bandwidth, magnitude, and frequency.
  • Frequency: An audible tone that is measured by the amount of air vibrating per second, typically measured in hertz (Hz).

Car Equalizer Buying Guides

These machines come in many different varieties, types, and brands. While all of them allow for more fine-tune control of your audio system, there are certain qualities and features you need to be privy to get the model that is the best fit for you.

  • Bands: The more bands, the finer tuned control you can have. Each band represents a certain amount of frequencies, but it’s important to know what frequencies they are, as it can vary depending on the equalizer. What is a mid-range for one equalizer isn’t the same for another.
  • Crossovers: These features control the lower and higher frequencies that can disrupt the music. The larger the decibel range, the more frequencies it can cover.
  • Adjustment Range: Often measured in decibels, the higher the range the more you can diminish or boost certain ranges.
  • Spectrum Analyzer: These are found on higher-end rigs as they give real-time measurements of your audio signal. They allow you a visual representation of your frequencies.
  • Bipolar Switching: This unique electrical system allows for increased voltage output by using twice as many quadrants compared to traditional systems.
  • Parametric Equalizers: A step above more common graphic equalizers. These allow even more adjustments in the form of bandwidth control, the primary frequency, and the level.
  • Sound Processors: Another higher-end part of the equalizer that allows it to automatically adjusts its setting based on the noise found in the car

Car Equalizer Installation

Best Car Equalizers: Review and Buying Guide (2018 Update)

Because you are going to be messing with electrical equipment, you’re going to need a wire stripper, crimper, and electrical tape along with a screwdriver and screws. Depending on your setup you might also need some wrenches, a drill, and wire ties.

Most equalizers are mounted above or below the dash, but a few can be put into the trunk. Wherever you mount yours, make sure to stay away from steel or other metal surfaces as this can interfere with your sound quality from vibrations.

When it comes to the wiring you’re going to need to strip a 16 gauge wire that is attached to the fuse box. In order to activate the turn-on signal, you’re going to need to attach the turn-on wire from the head unit – this is typically a blue wire.

You’re also going to need to connect the amplifier with RCA cables, use wire ties to keep everything that is needed together. Connect these RCA cables through the output of the amplifier into the input of the equalizer – make sure to avoid any power cables as this can distort your sound. Most sound systems will require approximately four different outputs – the front, center, subwoofer, and front.

From here it’s just a matter of hooking your battery back up and trying it out. As long as the equalizer is powered and doing its job properly, go ahead and put everything back together as you are ready to go.

Final Thoughts

When setting up your audio system there are a few pieces of equipment that stand out – speakers, amplifiers, and of course equalizers. Providing fine-tune control at your fingertips to create a unique sound that is perfectly tailored to your wants and needs, an equalizer is a must-have for your audio automobile rig. When picking a car equalizer you need to see how many bands it has, how much they can be adjusted, along with all the other features like crossovers and bipolar switching. Follow the proper installation instructions and you’ll be jamming out to great tunes in no time.
