Installation:

If your Miata did not come equipped with factory headrest loudspeakers,
you will need to install the clearwater Headrest Harness. See Full
Installation 1990-94 or Full Installation 1994-97½.

Installation Time:

There are two levels of installation. If you simply replace your factory
headrest speakers with the Clearwater speakers, installation time
should be approximately 25 minutes. If you need to install the Harness,
installation time should be approximately 1-2 hours for 1990-94 and
approximately 40 min. for 1994-97½. We strongly suggest that you do
the full installation to correct any potential incorrect Mazda factory wiring
mistakes. These were common in early cars…..

Replacement Install:

• Unzip the top of each headrest cover. Fold forward the cover and
remove the perforated white plastic cover. (If zipper is stuck, rub some
sort of lubricant on it to make it easier to unzip, otherwise you could
damage the zipper.)

• Remove the four small Phillips head screws that mount the factory
speakers to the black plastic rectangular speaker frame. Gently pry the
factory speaker from the frame.

• Remove the two slide-on speaker connectors from each speaker.

Remove factory speaker.

• You will need to pull each of the factory speaker wires through the
bottom of the black plastic frame. A rubber grommet surrounds each of
the wires.

• Now remove the three larger Philip screws that attach the black plastic
frame to the seat back. Remove the black plastic frame.

• Position the Clearwater speaker near the headrest and slide-on each
of the factory connectors.

• Gently spread the headrest foam apart and press into place each of
the Clearwater speakers. It is best to push the foam inwards. Screws are
not used to mount the speakers, the foam will hold them in place.

• Position the white perforated plastic cover in place and zip the
headrest cover. Do not pull zipper too hard or you may risk tearing the
zipper.
