Radio/Stereo Noise Filter Relay: Description and Operation
SYSTEM OPERATION
Filter, Choke, And Speaker Relay
Models equipped with the Infinity premium speaker package use this filter, choke, and speaker relay unit to control battery feed to the two
speaker- mounted amplifiers. The filter, choke, and speaker relay unit should be checked if there is no sound output noted from both of the front
door speakers and the A-pillar tweeters.
The filter, choke, and speaker relay unit is mounted to the lower instrument panel center brace, inboard of the Central Timer Module (CTM) and
directly above the 16-way data link connector. The filter, choke, and speaker relay unit can be accessed for service without instrument panel
disassembly or removal.
The filter, choke, and speaker relay unit cannot be repaired and, if faulty or damaged, the unit must be replaced.
