How to Install a Car Digital Equalizer

A car digital equalizer provides a more advanced alternative to its analog predecessor. With a lot of electronic gadgets going digital, it is also appropriate to change the analog equalizer into a digital version. Below are the necessary steps to follow when installing the device.

Tools and Materials

  • Screwdrivers
  • Connecting EQ patch cables
  • 10mm wrench

Step 1 – Detach the Negative Battery Cable

Detach the grounding cable or negative battery cable from the battery of the car. The grounding cable is the cable that connects the battery’s negative lead to the car’s chassis. Use a 10mm wrench or a crosshead screwdriver to loosen the clamp bolt securing the cable. Detach the clamp and pull out the cable from the battery.

Step 2 – Plan Where to Install the EQ

Some of the popular choices include the glove compartment, the trunk or under the dashboard. Choose the dashboard to make sure the installation is somewhere that you can easily reach when adjusting controls. If not, choose the trunk for simplicity. The space provides ample room for the installation without having to change or add to any vehicle hardware.

Step 3 – Detach the Stereo Unit

Detach the stereo unit from the car to gain access to the connections at the back of it. Removing the device from the car varies from one model to the other so check the manufacturer’s manual for correct removal procedures. Usually, this involves removing the dash cover and loosening the clips or bolts securing the device to the dashboard. After detaching the clips or bolts, pull the stereo out from where it is installed.

Step 4 – Connect the Stereo to the Digital EQ

Connect the patch cables at the back of the stereo. Newer models usually have input ports for digital equalizers. Simply connect the cable to the EQ jack to bridge the connection. As soon as the EQ is connected to the stereo, it will not need a separate source of power. While receiving signals from the stereo, it will also receive power supply from it.

Run the cables to the location of the equalizer. Use the same path designed for the speaker wires if possible. It may be necessary to remove some of the carpeting temporarily so that the cables can be hidden from view. Connect the cables to the correct input ports located at the back of the equalizer.

Step 5 – Secure the Stereo and Equalizer

Insert the stereo back into its original location in the dashboard. Tighten the screws and re-place the dash cover. It is also necessary to mount the equalizer to the car using the mounting hardware provided in its kit. This will depend on where it has been installed. Follow mounting procedures detailed in the manufacturer’s manual.

Step 6 – Reconnect the Battery

Reattach the grounding or negative battery cable back to the battery. Re-tighten the bolt on the clamp to secure it to the negative lead. Turn on the car and the stereo to check if the equalizer is correctly installed. The device can be controlled indirectly from the stereo.
