SYSTEM OPERATION
Speaker
Speaker system options include two or four speaker locations. On two-speaker systems, one full-range speaker is located in each front door.
Four-speaker systems add one full-range speaker in each rear side panel above the rear wheelhouse.
The premium speaker option upgrades all the speakers in the above locations to Infinity bi-amplified models. Infinity coaxial speakers are
mounted in the front doors. Each Infinity speaker features an integral amplifier and frequency filter unit. The amplifier of the radio is used to drive
the tweeters of the front door coaxial speakers. The speaker-mounted amplifiers drive the woofers at each speaker location.
Filter Choke/Speaker Relay
Models equipped with the Infinity premium speaker package use this choke/relay to control battery feed to the speaker-mounted amplifiers. The
choke/relay is mounted above the heater-A/C air distribution duct, under the right side of the instrument panel. The choke/relay can be accessed by
removing the glove box bin.
The choke/relay should be checked if there is a lack of bass and low frequency response noted at the front door speakers, and no sound output at
the rear speakers. The choke/relay cannot be repaired and, if damaged or faulty, it must be replaced.
