### Circuit Operation

The front speakers' location is in the front doors. The rear speakers' location depends upon the model:

• | On 2-door models, the rear speakers mount in the rear quarter trim panels.

• | On 4-door models, the rear speakers mount in the rear seatback-to-rear window shelf.

The radio incorporates an electronic memory for the following:

• | Preselected stations

• | Clock settings

The DOME fuse applies voltage at all times for the following circuits:

• | The radio clock

• | The memory circuitry

If this voltage source interrupts for any reason, reset the clock and the memory functions.

With the ignition switch in the ACC position or in the ON position, the ACC fuse applies the battery voltage to the radio. The ON switch applies voltage for all of the electronic radio functions. The radio is permanently grounded at G203.
