Three-Way FlushMount Car Speakers
Your Optimus Three-Way FlushMount Car Speakers provide clean
sound and each speaker can handle
up to 30 watts. The panel-mount design lets you easily mount the speakers so that they are flush with the
mounting surface. To get the best
sound from your speakers, read this
entire manual carefully for the proper
wiring and mounting procedure.
BEFORE YOU BEGIN
We recommend that you wire the
speakers to your sound system before
you mount the speakers so that you
can test the speakers and the wire
connections. Then, disconnect the
wires, route the wires, and m ount the
speakers.
If you are unsure about wiring
Note:
or mounting, we suggest you have a
professional install the speakers.

Notes:
• Be sure you match the speaker
wires to their corresponding positive (+) or negative (–) speaker
terminals to ensure proper phasing. Improper phasing can cause
poor bass response.
• If your speaker system includes
rear speakers, the same color
code applies. If your auto sound
system has a front to rear fader,
connect your speakers as follows:
MOUNTING THE
SPEAKERS
Follow these steps to mount the
speakers.
1. Remove the door panel you want
to mount the speaker on and find
a location where the speaker will
fit. Most vehicles hav e a prepared
cut-out area in the door for
speaker placement. Use the supplied template to be sure the location you choose is large enough
for the speaker opening.
To be sure the speaker will
Note:
not interfere with your vehicle’s
window mechanism, roll down
your vehicle’s window completely.
If the window has a hand crank,
be sure the speaker will not hinder
you from turning the crank.
2. Mark the mou nting hole locations
and outline the speaker on the
door panel using the supplied
template.

3. Drill a starter ho le inside the outlined area. Carefully remove the
area you marked, using a razor,
tin snip, or a hacksaw blade.
4. Drill three
1
/8-inch mounting holes.
5. Disconnect the wires from the
speakers and route them from
your sound system through the
door sill and to the speaker’s
mounting location. You might
need to drill a hole to route the
wire through the door sill. Some
cars have predrilled holes and
rubber tubes for routing wires.
Cautions:
• Be sure you allow enough slack
in the wire to prevent pulling the
wire front he speaker when you
open the door all the way.
6. Replace the door panel. Then,
pull the wires through the hole you
made for the speaker and connect
the wires to the speaker’s terminals. See “Wiring the Speakers.”
7. Mount the speaker as needed.
• If you mount the speaker on a
metal surface, align the moun ting holes on the speaker with
the three drilled holes and
secure the speaker with the
supplied screws.
• If you mount the speaker on a
non-metal surface, insert the
three supplied speed clips into
the mounting ho les to ensure a
firm mount and to protect the
mounting holes. Then align the
mounting holes o n the speaker
with the three drilled holes and
secure the speaker with the
supplied screws.
8. Align the speaker grille with the
speaker and press it onto the
speaker until it snaps into place.
• Tape any exposed wire to prevent the wire from being
pinched or cut when the door is
closed.
