marking the location for the holes, remove the speaker and drill
a pilot hole about 3/8 of an inch deep. Pilot hole should be smaller
than screws. DO NOT drill all the way through the mount. If you
do not have a drill you can use your screw driver to "force" the
screws into the plastic. It is not difficult, but we recommend
the speakers not be in place during this step as the screw driver
could slip and damage your new speakers.
