This bulletin applies to vehicles built before 5/1/2004. The customer may complain of hissing or crackling in one or more speakers, and may be misdiagnosed as a speaker or radio issue. This complaint can be verified by turning the radio to low volume or to 0 (mute) and listening to the audio system from the driver's seat for noticeable audible hissing or crackling noise. If the hissing noise is heard, do not replace the speakers or radio. Instead, the amplifier needs to be replaced. The replacement amplifier should have a date code of 1134. (The amplifiers have a small, square label near the connectors. The date code is the four digit number in the lower left corner of the label.) Note: If there is no hissing or crackling with the radio muted, then the system should be root caused and corrected as necessary. ______________________________________ Contact Us at CAGRIS@Chrysler.com for feedback related ONLY to this GPOP Tech Tip.
