The audio system is standard factory-installed equipment. The system uses an ignition switched source of battery current so that the system will only operate when the ignition switch is in the ON/RUN or START positions.
The audio system includes the following components
- Antenna
- Rear Window Antenna Module
- Power Amplifier
- Radio Receiver
- Speakers
OPERATION
For detailed operation instructions for the factory installed audio system, refer to the Understanding Your Instrument Panel section in the Owner's Manual.
DESCRIPTION
The antenna body and cable are secured below the quarter panel by the antenna cap nut through a mounting hole in the left rear quarter panel (1). The coaxial cable is then routed behind the instrument panel to the back of the radio.
Scheme 2
The antenna body and cable connects the antenna mast to the radio. The radio antenna is an electromagnetic circuit component used to capture radio frequency signals that are broadcast by local commercial radio stations in both the Amplitude Modulating (AM) and Frequency Modulating (FM) frequency ranges. These electromagnetic radio frequency signals induce small electrical modulations into the antenna as they move past the mast. The antenna body transfers the weak electromagnetic radio waves induced into the rigid antenna mast into the center conductor of the flexible primary antenna coaxial cable. The braided outer shield of the antenna coaxial cable is grounded through both the antenna body and the radio chassis, effectively shielding the radio waves as they are conducted to the radio. The radio then tunes and amplifies the weak radio signals into stronger electrical signals in order to operate the audio system speakers.
The liftgate glass contains the audio antenna (4) attached to the inside surface. Grid lines running horizontally form the antenna, which terminates to bus bars (1) at either side. Blade type terminals, also attached to the inside glass surface at the bus bars, form the beginning connection point for the radio frequency signal.
