Note: If you are drilling into fiberglass, use a small drill bit to drill pilot holes before drill-
ing the screw holes.
Drill through the corners of the hatched area where marked, then cut out the hatched 3.
area to create a cavity in the mounting surface. (The dashed line shows the total area
that will be covered by the radio fascia after installation.)
