Want the finest audio quality in your vehicle? Do you wish to spend hours in your car due to the high-quality music originating from the speakers? Why then not use an equalizer?

An equalizer or EQ is a sound engineering tool installed in a car audio system that modifies the output of various frequencies, allowing one to manage the level of the sound. I believe an equalization can improve the sound quality of any toy car’s speakers, regardless of how good they are.

There are various sorts of equalizers, each with unique features. The parametric and graphic equalizers. The graphic equalizer is user-friendly since it is pre-programmed with simple-to-control frequencies, has a wide variety of effects, and is less expensive than its parametric counterpart. The complexity of parametric equalizers stems from the fact that they permit additional adjustments beyond loudness, have a precise range of effects, and permit frequency adjustments. Always conduct thorough research on the desired product before to purchasing it.

This article will instruct you on how to connect an equalizer. Ensure that you have the essential equipment, which includes an equalizer, a receiver, an amplifier, two pairs of RCA cables, and tape. A receiver collects sound signals from the source, processes them, and supplies energy to the amplifiers that power the loudspeakers. An amplifier amplifies the low-level sound signal and makes it powerful enough to move the system’s speaker cones and produce sound. RCA cables transmit audio and visual signals from an input component to an output component. Remember that the length of the RCA cables must equal the distance between the receiver and the equalizer. The tape holds RCA cords together. Even if you have the best product on the market, hooking it is the most crucial step.

Receivers typically include fixed pre-amps or integrated amps. In this situation, the receiver should be connected to an equalizer using the methods below.

Step One

Unplug any connections before to beginning. On the back of your preamp or integrated amplifier are red and white input and output channels designated IN/OUT and L/R. Connect the white RCA jack pin to OUT/LEFT and the red RCA jack pin to OUT/RIGHT.

Step two

The INPUT or IN jacks on the rear of the equalizer are similarly colored red and white. While matching the colors, connect the RCA cable from the preamp or integrated amplifier.

Step three

Connect the second RCA cable to the pre-amp or integrated amplifier’s color channels with the second RCA cable.

Step four

Connect the second RCA cable to the back of the equalizer in the channels labeled OUTPUT or OUT, ensuring that the colors match.

Step five

Find INPUT/OUTPUT channels near the rear of the equalization. Connect the RCA cables from the receiver output to the equalization input while matching the colors.

Step six.

Connect the RCA cables from the receiver’s INPUT to the equalizer’s OUT channels.

Step seven

Turn on all three components, then adjust and regulate the knobs to your liking.

What happens if your receiver lacks pre-amp-out channels? That would be difficult. Well, it can be less challenging by making sure that your amplifier is integrated with the pre-amp IN and OUT channels.

Let’s examine how to directly connect the equalization to the receiver.

Step one

At the back of the receiver, there are input and output channels. Plugin the RCA cables into the OUT channels while matching the colors.

Step two

At the back of the equalizer, plug the red end of the cable to IN/RIGHT and the white end IN/LEFT.

Step three

Take the second RCA cable on the equalizer plugin the ends on OUT channels.

Step four

The receiver, plug in the other end of the cable with the red end on IN/RIGHT while the white end is IN/LEFT.

Step five

Turn on the equalizer and the receiver. Select “tape monitor,” and by now, the equalizer should be active. Adjust according to your taste and preference

There are instances where the pre-amps are fixed on the amplifier instead of the receiver. What should we do then?

We hook the equalizer directly to the amplifier using the following steps.

Step one

Check if your amplifier has pre-amp IN and pre-amp OUT channels. It is definitely, located at the back of the amplifier. With one pair of the RCA cable, plug into the pre-amp OUT while matching the red colors to RIGHT while white goes to LEFT.

Note that in some amplifiers, the channels will be marked as “tape monitors input/output. ” Don’t panic.

Step two

From the amplifier, plug the cable into the pre-amp IN channels. Red goes to RIGHT, and White goes to LEFT.

Step three

Switch on the tape monitor or the pre-amp connection buttons. You can now manipulate the control and adjust the knobs according to your preference.

In the procedures above, the equalizers are installed on the dashboard. In other vehicles where every space matters, the equalizer is remote-mounted, thus controlled using a remote. All you need is to make sure it is between the amplifier and the receiver.

You first have to decide the location of the equalizer bearing in mind you might add the amplifiers later, and you’ll need to run wires to the amplifier and the receiver.

Hooking up the equalizer should follow these steps.

Step one

You need to get access to the channels on the receiver, so you’ll have to pull it out slightly. The simple way is to pull off the plastic piece covering the dashboard, and it will slightly come out.

Step two

Plugin the cables into the pre-amp OUT matching colors and tape them together to avoid parting.

Step three

On your equalizer, plug in the RCA cables into the pre-amp IN. Tape the cables together so they can run from the receiver to the equalizer through the dash.

Step four

At this point, you need to mount your equalizer. To avoid interference amount on rubber material or a flat surface, avoid metal bases, interfering with the sound. If you must, use pieces of rubber in between.

Step five

Turn off the ignition and remove the key before installing to avoid shock.

Step six

This step entails how to ground a wire:

  • On the equalizer, you will see three wires. The black one is the ground wire.
  • Remove a bolt near the mounting location on the equalizer.
  • Scratch away any paint around the location.
  • Fasten a ring at the end of the wire and bolt it to the vehicle.
  • Make a hole on the base of the metal if there is no location. Avoid making it on the gas tank or brake line.

Step seven

In this step, you need to connect with the power cable. Look for a yellow/red wire on the equalizer. Connect the wire to the power cable on the receiver or any other source of 12v variable power in the fuse box. If you don’t know how to locate the wiring system, use the manual.

Step eight

Connect the remote turn-on wire. Identify a blue wire with white strips labeled on the equalizer. Look for a similar color of wire on the receiver, but it can be any other color. Connect these two wires after routing them around the vehicle. You Wires should be crimped together to make a connection and wrap them in electrical tape to avoid short.

Step nine

Turn on the ignition to test the equalizer. Turn on the radio and check if the equalizer does is working correctly.

Step ten

Put back the receiver after pushing all the wiring in the dashboard. Place a frame to cover the receiver back to place.

By now, we both agree that hooking up an equalizer is super easy. You make sure you’re armed with all tools on time, and your car ignition has to be off. You don’t want a slight forgetfulness messing everything up. Use manuals where necessary and if they can’t help, call an expert. Remember, if you want to overcome your speakers’ limitations go for the equalizer with the best controls. Just make sure your hooking up is perfect to avoid damages or anything else interfering with the sound output.
