6- x 9-Inch 2 Way Flush-Mount Speaker System

CHOOSING A LOCATION

For the best performance, install these
speakers on a solid, firm surface that
does not vibrate at high volume leve ls.
We recommend you mount the speak­ers in the door panels or the rear
deck.

Note:

Cardboard or fiber panels are

not good mounting surfaces.

(illus showing suggested
mounting area.)

INSTALLING THE
SPEAKERS

1. Use the supplied template to mark
the speaker opening and the
mounting-screw hole locations.

2. Cut out the marked speaker open­ing in the mounting surface.

Note:

Steel door panels and the
rear deck (behind the upholstery)
might already have large cut-out
areas for recessing the speaker.

3. Drill the four mounting-screw
holes.

Caution:

into anything behind the mounting
surface.

Be careful not to drill

As you are deciding on a location,
carefully inspect the area behind the
proposed mounting surface.

• There must be a clear unob­structed area of at least 3 inches
(76.2 mm) behind the panel.

• If it is a door location, check to be
sure the window, window mecha­nism, and window handle will
clear the speaker.

Note:

Make sure the window

opens and closes properly.

4. If necessary, route new speaker
wire from the autosound system to
the mounting area.

Cautions:

• Avoid routing speaker wires

near moving parts, sharp
edges, or where they will be
pinched or stepped on. You can
usually route them along the
channel beneath the vehicle’s
door facings.

• If you selected door locations,
you might need to punch a
small hole in the door edge
(near the door hinges) to route
the wires into the door. Leave
enough slack wire to open the
door all the way.

5. Securely connect the positive (+)
and negative (–) stripped speaker
wire ends to the corresponding
speaker terminals.

(illus - show the speaker
wires properly wrapped
around the speaker’s ter­minals.)

Cautions:

• Improper phasing can cause

poor bass response. To ensure
proper phasing, you need to
match your autosound sys­tem’s positive (+) and negative
(–) speaker wires to the corre­sponding positive (+) and nega­tive (–) speaker terminals.

If you have a two-speaker sys­tem:

with proper polarity)

If you have a four-speaker sys­tem (front and rear):

diagram for connec­tion to four speakers
with proper polarity)

6. Remove the grille from each
speaker’s mounting bracket to
expose the mounting holes.

7. Place the mounting bracket on the
speaker.

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

(illus – show how
the bracket fits on
the speaker.)
