drill inside and close to the line you
have marked.
Installation from the rear of the bulkhead
A 4
Choose the 5 3 ⁄
8
inch (13.6 cm) diameter hole size if you can comfortably hold the
speaker enclosure from behind the wall while installing screws from the front. This is
the preferred mounting method. If the hole you cut is not perfect, any slight overcut
will be hidden by the grille.
Determine that there is enough room by
reaching into the mounting area and
sweeping with your hand. Determine
where you will drill the hole for the
speaker. You should also experiment by
placing the speaker enclosure behind
the bulkhead before making your final
selection. Any orientation of the speaker
enclosure is acceptable. A 1
CAUTION: Determine whether any
obstacles exist behind the mounting
surface. To be certain, contact your boat
manufacturer or dealer. Also, be certain
that the enclosure will fit within the mount-
ing area before drilling any holes.
Place the template over the area
where the speaker is to be located
and mark the 5
3 ⁄
8
inch (13.6 cm)
hole with a metal scribing tool or
pencil.

The round outer edge of the template
shows how much room to allow for
the grille. The long end is used to plan
for room for the enclosure behind the
bulkhead. There are two perforated
circles in the template. Snap out the
smaller one. A 2
