How to Install a Car Stereo in a 93 Mazda Protege

The original stereo system in the 1993 Mazda Protege was an AM/FM stereo cassette deck. You can upgrade or replace a malfunctioning stock unit with relative ease. Mazda employs a system for removing factory stereos using DIN removal tools. The special tools are available through Mazda or Ford dealerships, or can be purchased through many retail car audio outlets. You will also need an installation kit to mount your new stereo.

Things You'll Need

• Adjustable wrench
• Mazda DIN removal tools
• Wiring harness adapter
• Mazda stereo installation kit (with mounting sleeve)

Instructions

1. Lift the hood of the Mazda to access the grounding cable connected to the battery. Use an adjustable wrench to loosen the bolt holding the cable to the battery terminal. Remove the cable from the negative battery lead post.

2. Insert the DIN removal tools into the holes on either side of the Protege's stereo face. Push the tools into the holes until they lock into place.

3. Pull outward on the tools while pulling the stereo from the Mazda's dashboard.

4. Unplug the white plastic wiring connectors from the outlets on the back of the factory stereo. Disconnect the antenna cable from the radio.

5. Insert the installation sleeve from the Mazda stereo installation kit into the stereo mounting dock.

6. Plug the white stereo wiring connectors into the corresponding connectors on the wiring harness adapter.

7. Plug the wiring harness adapter connectors into the two outlets on the back of the new stereo. Plug the antenna cable into the antenna outlet on the back of the aftermarket radio.

8. Slide the new stereo into the stereo dock opening of the dashboard until it locks into place.

9. Replace the grounding cable onto the negative battery terminal and tighten the cable's clamp with the wrench. Close the hood.
