Car Audio Equalizers: What are they?

A car audio equalizer is a device which adjusts the sound output from your stereo speakers according to the type of vehicle you drive. It’s purpose is to make the sound more pleasant for drivers while driving at high speeds, and it does so by adjusting the frequency response of your stereo speakers.

The most common types of car audio equalizers are the Pioneer AVIC-6000NEX (also known as the “Pioneer NEX” or “Super NEX”), the Denon D2000, and the JVC KD-X330BT. All these models have been designed with high quality components and are very popular among audiophiles.

They’re all made by different manufacturers and differ in their design features, but they share many similarities.

What do they do?

All three of them adjust the speaker’s frequency response to suit your specific vehicle. The Pioneer AVIC-6000NEX and the Denon D2000 adjust the bass and treble frequencies respectively, while the JVC KD-X330BT adjusts both bass and treble. You may want to use one or another of these equalizers depending on how you like your music to sound.

How do I choose between them?

The best way to choose between them is to listen to each one and see which one sounds better to you. You’ll also need to take into consideration the space available in your dashboard. The JVC KD-X330BT is quite large and may not fit in smaller vehicles.

How does it work?

All three of these equalizers work by adjusting the speaker’s frequency response to make music sound better at high volumes, as well as adding extra bass, if desired. They all have different features, so read their descriptions to see which one you want. If you don’t need all of the extra features, you may be able to save some money by buying a cheaper equalizer.

How do I connect it to my stereo?

Once you have chosen an equalizer, follow these steps to connect it to your stereo:

1. Find a spot to mount the equalizer in your dashboard.

The location you choose must be easily accessible so you can adjust the settings on it while driving.

2. Locate the “line-out” on your stereo.

This will be a red and white output usually marked by the words “line out”, “aux”, or something similar.

3. Connect one end of the auxiliary cable to the “line out” on your stereo.

Connect the other end of the cable to the “input” on your equalizer.

4. Turn on your stereo and equalizer.

Adjust the settings on your equalizer until you get the desired sound quality.

How do I use it?

Although car audio equalizers are simple to use, they do take a little getting used to. You must learn to use your eyes as well as your ears to adjust the settings so that you get the best quality sound. Start by turning the bass boost up one or two notches and listen to the music. If you want more bass, turn it up until you get the desired effect. Next, use the treble control to boost the high frequencies if needed. Finish off by turning the mid-range and presence controls to adjust the mid-range frequencies.

What is it made of?

Car audio equalizers are made up of several different parts, all of which are important for its proper functioning. The most important parts are the amplifier, the bass boost circuit (in models with bass boost), the rotary controls, and the wiring. The rotary controls adjust the sound frequencies. The amplifier boosts the sound output of the stereo. The bass boost circuit increases the low frequency sounds. Wiring is used to connect the equalizer to your car battery and stereo. There will also be a power supply that plugs into your car’s cigarette lighter, which the wiring attaches to.

How do I clean it?

To keep your equalizer looking good and in good working condition, wipe it down with a dry cloth occasionally. Never use any cleaning agents or water on it, as this may damage the materials of which it is made.

What if I want to hook up my mp3 player or connect external speakers?

If you want to connect your mp3 player or connect external speakers, then you may need an FM transmitter. An FM transmitter plugs into your equalizer and broadcasts a clear signal so you can play your music through your car speakers. You can also buy speaker wire that consists of two parts: one part connects to your stereo, while the other part connects to the speakers. There are several types of plugs, so make sure you buy the right type of speaker wire for your stereo.

Car Stereos

Car antennas are used to pick up signals from local radio stations. If you live in an area that doesn’t have good reception, you may need to install an antenna on your roof or buy a replacement antenna that is better at picking up radio signals.

Car Stereo Accessories

There are many ways to customize and improve the performance of your car’s sound system. Car stereos include many different features like Bluetooth and HD radio.

You can also improve the sound quality by adding speakers and subwoofers.

Car Subwoofers

A subwoofer is a speaker that is designed to produce low-pitched audio frequencies, such as those produced by drums or bass guitars. A subwoofer can enhance the sound of any vehicle.

There are many types and sizes of subwoofers.

Car Speakers

Car speakers are used to reproduce sound. Most vehicles come with speakers already installed, but you may want to add more.

Car speakers come in different sizes and shapes, like cubes or domes. They can be mounted in the doors or dashboard, or they can stand alone.

Tuners & Antennas

A tuner is a device that picks up radio signals. If you listen to the radio on a regular basis, then installing a tuner in your vehicle may improve your listening experience.

A tuner can pick up on different types of transmissions, like AM and FM, or just one specific type.


An amplifier is a device that makes sounds louder. Most vehicles already come with an amplifier to power the speakers.

If you find that the volume on your car stereo doesn’t get loud enough for your liking, then you can install an additional amplifier.
