Advanced Audio Sound Speaker System

The advanced audio sound system consists of seven speakers and an amplifier. There is a 0.75 in. tweeter in each of the front doors, a woofer in all four doors (6 in. ERS speaker in each front door and 5 in. ERS speaker in each rear door), and a 5 in. subwoofer (located on the rear shelf panel for the sedan. In the wagon, the subwoofer is mounted to the left side wheelhouse area). The amplifier module is found attached to the I/P beam. The supporting structures are rigid as to not allow unwanted resonance or loss in bass frequencies for both the subwoofers and the amplifier.

The amplifier contains all of the necessary signal processing and power amplifier circuitry that is not contained within the radio and has dedicated battery circuits, a battery fuse, and ground circuits for its power source. The wiring from the radio outputs to the amplifier inputs consist of a harness containing four twisted pairs, one for each audio channel. The radio also supplies a switched battery control signal to the amplifier for the purpose of controlling the module's ON/OFF modes. The speaker outputs are not grounded, but are protected against accidental grounding or connecting to battery.
