Installing the SPEAKERS

Once the mounting locations have been established, run speaker cables from the amplifier outputs to the mounting locations. If you are running cables through bulkheads, drill holes for the cable and use a urethane or plastic grommet to protect the wire from chafing in the hole. Make sure that the cables will clear any mechanical devices in the boat and secure them with wire ties.

If you have any questions about the installation or setup of your coaxial speaker system not covered in this manual, please contact your dealer or technical support.

COAXIAL INSTALLATION PROCEDURE Diagram A (page 7) shows the typical

installation procedure into a fiberglass panel, using the supplied hardware. Always follow proper safety procedures. Use eye-protection at all times and a dust mask and gloves when cutting.

1)Choose a flat mounting surface that has sufficient depth and air space behind it to accept the speaker.

2)Using a hole saw or jigsaw, cut a mounting hole for your respective speaker model (see “Mounting Hole Diameter (E)” specifications, page 2). If using a jigsaw, tracing the supplied mounting template will provide you with an accurate line on which to cut.

3)Run the speaker cable from the amplifier output to the mounting location.

4)Place the speaker in the hole (or use the mounting template) and mark the screw hole locations using a sharp, pointed tool.

5)Remove the speaker and drill a pilot hole (see Pilot Hole Recommendation chart,

page 7) in each of the screw locations. It is also advisable to use a hand-driven countersink tool on each hole to further inhibit gel-coat cracking of fiberglass panels.

6)Connect the speaker wires from the amplifier to the woofer connections.

See Wiring Diagram on page 5.

7)Place the speaker into the opening.

8)While holding the speaker firmly in its mounting location, place the #8 x 1 3/8-inch Phillips pan-head mounting screws (with washers) and snug in a criss-cross pattern, then tighten with a hand screwdriver in a criss-cross pattern.

Non-standard installations may require different hardware. Always use marine-grade, stainless-steel fasteners to ensure a secure, reliable installation.
