2004 Honda Civic: Radio Installation & Instructions
(Hemera Technologies/AbleStock.com/Getty Images)

Owners of the 2004 Honda Civic had the option of the standard AM/FM stereo with in-dash CD player or a multi-disc CD changer. Install an aftermarket radio in the event of a malfunctioning stock stereo or to upgrade the factory stereo system. Use a Honda aftermarket stereo installation kit to fit the new radio into the Civic's stereo dock. For an easier connection, choose a wiring harness adaptor to avoid having to splice the vehicle's stereo wiring to hook up the aftermarket radio.

Things you need

  • 10mm wrench
  • Trim panel removal tool
  • Phillips-head screwdriver
  • 8mm socket and drive
  • Wiring harness adaptor

  • Flat screwdriver

    Unplug the stereo wiring and antenna cable from the back of the factory stereo.

    Slide the Honda stereo-installation kit into the stereo bracket and replace the two 8mm bolt screws.

    Insert the aftermarket radio into the Honda's stereo kit. Push the unit into the sleeve of the kit until it snaps into place.

    Plug the Civic's antenna cable into the outlet labelled "FM ANT" on the back of the radio.
