Tools required
You will need the following tools to complete this installation:
• Phillips-head screwdriver.
• An appropriate cutting tool for the surface to be cut. For installation in fiberglass or wood,
we recommend a sabre saw. Use a short blade, and have some extra blades available. A
hole saw may also be used. Large diameter hole saws are available and they allow you to
make circular cuts on a flat surface.
• Drill with...

Test the speakers
It is a good idea to test your system before installation. With the power turned off, connect
the receiver to the speakers.
The provided speaker cord consists of two insulated wires; one is marked or ribbed, and is
always positive (+). The plain wire is always negative (–). The wires correspond to the red (+)
and black (–) terminals on the back of the speaker, receiver, or amplifier. Place the stripped
end of...

Installing Your Speakers From The Rear Of The Bulkhead

Drill a starter hole that is large enough
for your sabre saw blade. Be sure to
drill inside and close to the line you
have marked.

Hold the speaker enclosure up to the
hole from behind the bulkhead and find
the best position for the extended
portion of the enclosure. Be sure the
enclosure is hidden behind the bulkhead.
If the enclosure does not fit, use the file
or rasp to enlarge the hole. Use a half-round file or wood rasp to
smooth out any roughness in the hole
you have cut. Using the sabre saw, cut the hole for the
speaker, carefully following the...

Drill the marked holes using a 1⁄8 inch
(.32 cm) bit. Use a center punch to make
a slight indentation for your drill bit. This
will keep the drill bit from “walking” away
from the mark you have made.

Connect the speakers. Be sure the receiver or
amplifier is turned OFF. If possible, disconnect the
power source. Use the supplied silicone-filled wire
nuts to secure the ends of each wire pair. Place the
stripped end of the positive (+) right channel receiver
wire together with the stripped end of the positive (+)
right speaker wire. Place the wire nut over the ends of
the wires and turn it in a clockwise direction. Turn it...
