Three-Way Bass Reflex Car Speaker System
(120-1725) Features Faxback Doc. # 38063

Your Optimus Three-Way Bass Reflex Car Speaker System is designed to give
you clean sound with powerful bass. The system is ideal for rear-deck
mounting.

To get the best sound from your speakers, please read all of these
instructions carefully for the proper wiring and mounting procedures.

BEFORE YOU BEGIN

We recommend that you connect your autosound system to the speakers before
you mount them so you can test the speakers and the wire connections. When
you verify that everything works properly, turn off your autosound system
and mount the speakers.

NOTE: If you are unsure about the following installation process, we
recommend that you have a professional install the speakers.

Three-Way Bass Reflex Car Speaker System
(120-1725) Wiring the Speakers Faxback Doc. # 38064

Connect two speakers to your auto sound system as shown.

NOTES:

If your autosound system has a front-to-rear fader, follow the
instructions in the audio component's manual for the correct speaker
connections.

To ensure proper phasing, match the speaker wires to the corresponding
red (+) or black (-) speaker terminals. Improper phasing can cause
poor bass response.

CAUTIONS:

Do not connect any of your speaker wires to chassis ground. Use all
four wires to connect the speakers to your vehicle's autosound system.

Do not connect four speakers to your car stereo/amplifier unless it is
designed for a four speaker connection. See your stereo/amplifier's
owner's manual for instructions.

ROUTING SPEAKER WIRE

Avoid routing speaker wire near moving parts or sharp edges. You can
usually route it along the wiring channel beneath the vehicle's door
facings by carefully removing the molding that holds the carpet in place.
After routing the speaker wire, replace the molding.

MOUNTING THE SPEAKERS

After you have connected the speakers and turned on your autosound system
to ensure that everything is working properly, turn off your autosound
system and mount the speakers.

1. Select a flat area (such as your car's rear deck) for the mounting
surface. The surface should be sturdy enough to support the weight of
the speakers.

2. Use the speaker cabinet's base as a template to mark the desired

mounting position. Then determine the center of the mounting position.

3. Drill a hole 1/4-inch wide in the center of the mounting position.

4. Attach the bolt to the bottom of the speaker cabinet and secure the
bolt using a Phillips screwdriver.

5. Position the speaker cabinet on the mounting surface by inserting the
bolt through the drilled hole.

6. Underneath the mounting surface, place the washer over the bolt. Then
thread and tighten the wing nut until the speaker cabinet is secure.
