1964.5-1973 Mustang Kick Panel Speaker Install Instructions

For this install, we chose custom Autosound kick panels with a 6 ½ inch speaker system for a 1967-1968 Coupe or Fastback Mustang. If your Mustang is a different model, make sure the kick panels you use are designed to fit your Mustang.

These kick panels are direct replacements that attach to the factory kick panel location. They feature a black plastic mold that can be dyed to match your interior color.

Parts and Tools Needed:

  • Phillips Head Screwdriver

Step 2: Install Speaker Insulation

Grab a sheet of kick panel insulation and cut it so it conforms to the shape of the speaker panel. Make sure to cut out a section in the center so the insulation forms around the speaker. Remove the adhesive seal on the back and attach the insulation to the kick panel around the speaker. This will help lessen the flex of the plastic and stop unwanted noise or buzzing. Repeat this process for both kick panels.

Step 3: Remove Door Sill

Locate the door sill panel at the base of the inside section of the door. Remove the panel by unscrewing all nine Phillips head screws on each side. Repeat this process for the opposite-side door.

Step 4: Remove Factory Kick Panels

The original kick panels on your classic Mustang are held in place with two Phillips head screws located in the top-central and bottom-central sections of the kick panel. Remove the screws from both kick panels. There is a curved lip along the door's opening edge so, once the screws are removed, pull the panels towards the back of the car to release them.

Step 5: Install Kick Panel Insulation

For additional help with cabin temperature and road noise, lay down adhesive spray on the areas of the kick panel around the speaker. Cut a sheet of Mustang kick panel insulation to match the size of the kick panel. Make sure the perforated center section of the insulation is over the speaker.

Step 6: Connect Speaker Wire to Sound System

Fold the perforated opening in the insulation back. Run the speaker wire through the opening. Connect the speaker wires to the terminals located in the under dash wiring harness. Once they're connected, test the Mustang speakers before you finish installing the kick panels.

Step 7: Install New Kick Panel

Install the new kick panel by pressing it in place over the door opening lip. The panel uses the pinch weld and door sill plate to hold it in position. If the connection is not as secure as you would like, mark the location of the factory screws and drill two small holes in the same locations on the new kick panel. Install two new screws to hold the panel in place.

Reinstall the aluminum door sill on your Mustang by inserting it over the top of the kick panel. Reinstall each of the factory screws with a phillips head screwdriver and tighten them down. Repeat this process for the door sill on the opposite side.
