Radio/Stereo: Description and Operation

AUDIO SYSTEM
Several combinations of radio receivers and speaker systems are offered as optional equipment. The audio system uses an ignition switched source of battery current so that the system will only operate when the ignition switch is in the ON or Accessory positions.

The audio system includes the following components:
- Antenna
- Power amplifier (with premium speaker system only)
- Radio noise suppression components
- Radio receiver Speakers

The vehicle has two speaker systems:

Standard Speaker System
- Two instrument panel speakers
- Two door speakers
- Two rear quarter panel speakers

Infinity Amplified Speaker System
- Amplifier mounted under the passenger seat
- Two instrument panel speakers
- Two door speakers
- Two rear quarter panel speakers

See the owner's manual in the vehicle glove box for more information on the features, use and operation of each of the available audio systems.

INTERFERENCE ELIMINATION
Some components used on the vehicles are equipped with a capacitor to suppress radio frequency interference/static.

Capacitors are mounted in various locations internal to the alternator, instrument cluster and windshield wiper motor.

To eliminate radio interference, ground straps are used in different areas of the vehicle. These ground circuits should be securely tightened to assure good metal to metal contact. The ground straps conduct very small high frequency electrical signals to ground and require clean surface contact area. The radio ground wire is supplied from the instrument panel harness and is attached to the rear of the radio. Some engines have other ground straps to eliminate further radio interference:

- Engine to shock tower.
- Engine to transmission.
- Muffler to bumper beam.

Radio resistance type spark plug cables in the high tension circuit of the ignition system complete the interference suppression. Faulty or deteriorated spark plug wires should be replaced.

REMOTE AMPLIFIER
The amplifier is located under the right front seat.

When the radio system is ON, and all or some speakers are not operating or have a noise distortion refer to the diagnostic tests.

The amplifier provides unique sound equalizations when the convertible top is in the up position or in the down position. The amplifier remembers which mode it is in as long as the battery voltage (B+) is supplied to the amplifier. If the battery voltage is removed for only a few minutes by:
- Disconnecting the battery
- Dead battery
- Fuse Removal
- Amplifier disconnected

The amplifier reverts to a top up condition even if the top is down. If the amplifier mode does not match the convertible top position, operate the convertible top one cycle and this will reset amplifier to the correct mode.

REMOTE CD CHANGER
The remote CD changer is located in the center console and is capable of holding up to six discs in a magazine.

The magazine can be ejected at anytime that the ignition switch is in the ON position. After the ignition switch is turned OFF, the magazine can only be ejected within one minute. After that period, the magazine will be locked in the CD changer.
