(3) Turn the radio off. Turn the ignition switch to
the Off position. Disconnect and isolate the battery
negative cable. Remove the radio and the amplified
subwoofer. Check both the speaker feed (+) circuit
and return (–) circuit cavities for the inoperative
speaker location(s) from the radio wire harness con-
nectors and to the amplified subwoofer for continuity.
In each case, there should be continuity. If not OK,
repair the shorted speaker feed (+) and/or return (–)
circuit(s) to the speaker as required. If OK, replace
the amplified subwoofer.

REMOVAL

(1) Disconnect and isolate the battery negative
cable.
(2) Remove the center console (Refer to 23 -
BODY/INTERIOR/CENTER CONSOLE - REMOV-
AL).
(3) Disconnect wire harness retainer.
(4) Disconnect wire harness connector.
(5) Remove the mounting screws from the side of
the console.
(6) Open console lid and remove the retaining fas-
teners from the console.
(7) Remove amplified subwoofer from console.

INSTALLATION

(1) Install amplified subwoofer to console.
(2) Install retaining fasteners to the top of the con-
sole.
(3) Install the mounting screws to the side of the
console.
(4) Connect wire harness connector and retainer.
(5) Install the center console (Refer to 23 - BODY/
INTERIOR/CENTER CONSOLE - INSTALLATION).
(6) Connect the battery negative cable.
ANTENNA BODY & CABLE
DESCRIPTION
All models use a fixed-length stainless steel rod-
type antenna mast, installed on the right front cowl
side panel of the vehicle. The antenna mast is con-
nected to the center wire of the coaxial antenna
cable, and is not grounded to any part of the vehicle.
To eliminate static, the antenna base must have a
good ground. The antenna coaxial cable shield (the
outer wire mesh of the cable) is grounded to the
antenna base and the radio chassis.
The antenna coaxial cable has an additional dis-
connect, located behind the right end of the instru-
ment panel between the radio and the right cowl side
panel. This additional disconnect allows the instru-
ment panel assembly to be removed and installed
without removing the radio.
DIAGNOSIS AND TESTING - ANTENNA BODY
AND CABLE
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, (REFER TO
BEFORE ATTEMPTING ANY STEERING WHEEL,
STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE
TO TAKE THE PROPER PRECAUTIONS COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
The following four tests are used to diagnose the
antenna with an ohmmeter:
• Test 1 - Mast to ground test
• Test 2 - Tip-of-mast to tip-of-conductor test
• Test 3 - Body ground to battery ground test
• Test 4 - Body ground to coaxial shield test.
The ohmmeter test lead connections for each test
are shown in Antenna Tests (Fig. 1).
NOTE: This model has a two-piece antenna coaxial
cable. Tests 2 and 4 must be conducted in two
steps to isolate a coaxial cable problem; from the
coaxial cable connection under the right end of the
instrument panel near the right cowl side inner
panel to the antenna base, and then from the coax-
ial cable connection to the radio chassis connec-
tion.
Fig. 1 Antenna Tests
TEST 1
Test 1 determines if the antenna mast is insulated
from the base. Proceed as follows:
(1) Unplug the antenna coaxial cable connector
from the radio chassis and isolate.
