RAM 2500 Truck 4WD V8-5.9L VIN Z (1997)
Audio Control Relay: Description and Operation
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.
