How to connect an after market car stereo to a factory 6-disc changer

Updated March 23, 2017

Vehicles equipped with multi-disc CD changers enable drivers to play a wide variety of music without having to worry about changing discs. If you want to replace your stock deck, install an aftermarket stereo unit and connect it to your factory installed 6-disc CD changer. The new stereo can be connected to the changer by harness adaptors available through your local dealership or consumer electronic outlet.

Disconnect the negative battery cable from the terminal. Use a wench to loosen the cable's clamp and move the cable away from the battery until the stereo is connected to the changer.

Gather the stereo wiring in the vacant stereo mounting dock (after the factory stereo has already been removed).

Plug the stereo wiring from the vehicle into the wiring harness adaptor.

Plug the power supply and turn-on lead cables from the CD changer into the leads of the harness adaptor.

Plug the wiring harness adaptor leads into the rear panel of the aftermarket stereo. Connect the antenna cable to the FM outlet on the back of the new radio.

Install the new stereo unit into the dashboard stereo mounting dock of the vehicle. Follow procedure for installing an aftermarket stereo detailed in your vehicle's repair manual.

Place the negative battery cable back onto the terminal. Tighten the cable to the post with the wrench.
