SPEAKER
DESCRIPTION
STANDARD - JR41
The standard equipment speaker system includes
speaker in four locations: One 15.2 cm X 22.9 cm (6
in. X 9 in.) speaker is installed in each front door and
one 15.2 cm X 22.9 cm (6 in. X 9 in.) speaker is
installed outboard at each end of the rear shelf
panel.
STANDARD - JR27
The standard equipment speaker system includes
speaker in six locations: One 15.2 cm X 22.9 cm (6 in.
X 9 in.) speaker is installed in each front door, one
15.2 cm X 22.9 cm (6 in. X 9 in.) speaker is installed
in each quarter trim panel and one 6.4 cm (2.5 in.)
speaker installed in each end of the instrument
panel.
PREMIUM
The optional premium speaker system includes
speakers in six locations: One 15.2 cm X 22.9 cm (6
in. X 9 in.) speaker is installed in each front door,
one 15.2 cm X 22.9 cm (6 in. X 9 in.) speaker is
installed outboard at each end of the rear shelf panel
and one 6.4 cm (2.5 in.) speaker installed in each end
of the instrument panel. The system includes a sep-
arate 120 or 150 watt amplifier located under the
front passenger seat.
OPERATION
Two wires connected to each speaker, one feed cir-
cuit (+) and one return circuit (–), allow the audio
output signal electrical current to flow through the
voice coil. For complete circuit diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.

WARNING: DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, SEAT BELT TENSIONER, SIDE AIRBAG, OR
INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE, THEN WAIT TWO MIN-
UTES FOR THE AIRBAG SYSTEM CAPACITOR TO
DISCHARGE BEFORE PERFORMING FURTHER DIAG-
NOSIS OR SERVICE. THIS IS THE ONLY SURE WAY
TO DISABLE THE AIRBAG SYSTEM. FAILURE TO
TAKE THE PROPER PRECAUTIONS COULD RESULT
IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSI-
BLE PERSONAL INJURY.
CAUTION: The speaker output of the radio is a
“floating ground” system. Do not allow any speaker
lead to short to ground, as damage to the radio
may result.
(1) If all speakers are inoperative, check the radio
fuses in the Junction Block (JB). If OK, go to Step 2.
If not OK, repair the shorted circuit or component as
required and replace the faulty fuse.
(2) Check the amplifier fuse (if equipped) in the
junction block. If OK, go to Step 3. If not OK, repair
the shorted circuit or component as required and
replace the faulty fuse.
(3) Turn the ignition switch to the ON position.
Turn the radio receiver ON. Adjust the balance and
fader control controls to check the performance of
each individual speaker. Note the speaker locations
that are not performing correctly. Go to Step 4.
(4) Turn the radio receiver OFF. Turn the ignition
OFF. Disconnect and isolate the battery negative
cable. If vehicle is
n o t
equipped with a amplifier,
remove the radio receiver. If vehicle is equipped with
an amplifier. disconnect wire harness connector at
output side of amplifier. Go to Step 4.
(5) Check both the speaker feed (+) circuit and
return (-) circuit cavities for the inoperative speaker
at the radio receiver wire harness connector for con-
tinuity to ground. There should be no continuity. If
OK, go to Step 5. If not OK, repair the shorted
speaker feed (+) and/or return (-) circuits(s) to the
speaker as required.
(6) Disconnect wire harness connector at the inoper-
ative speaker. Check for continuity between the
speaker feed (+) circuit cavities of the radio receiver
wire harness connector or if equipped, the amplifier
wire harness connector and the speaker wire harness
connector. Repeat the check between the speaker
return (-) circuit cavities of the radio receiver wire har-
ness connector and the speaker wire harness connector.
In each case, there should be continuity. If OK, replace
the faulty speaker. If not OK, repair the open speaker
feed (+) and/or return (-) circuits(s) as required.
