Mustang Kick Panels with Speaker Openings (1967-1968) Installation Instructions
2. The displacement on the speaker holes on these kick panels was pretty shallow for typical Mustang 6.5 inch speakers
so I used inexpensive 1 inch standoffs for installation of my speakers.
3. I also used a Mustang Dynamat Xtreme Speaker Kit
on the backside of my kick panels to make the plastic more rigid. This will lessen the flex and stop unwanted noise or buzzing.
4. Now that the new kick panels are prepped with the new speakers and Dynamat, remove the original Mustang kick panels
. To do so, remove the door sills by removing all nine Phillips head screws on each side. The original kick panels are held in place with two Phillips head screws. Remove them. There is a curved lip along the door's opening edge, so you have to pull the panels towards the back of the car to release them.
6. The insulation comes with a perforated opening for the speaker wire. Run it through the opening and connect it to your sound system. Once they're connected, test the Mustang speakers
before you finish installing the kick panels.
7. To install the kick panel, I simply pressed it in place over the door opening lip. I don’t plan on using additional installation screws because it is a tight fit, and the kick panels did not come with pre-drilled holes for any mounting screws. However, if I notice the kick panels flexing as time passes, I will install self-tapping screws.
