3.5" speaker assembly Before replacing a speaker part for crackles or rattling noises make sure to take the following steps: 1. Check for electrical harness routing too close to speaker's rear moving parts, improper connection, and/or harness pinch or damage. 2. Ensure no loose components, including trim grilles, fasteners, surrounding IP parts, etc. were found when removing the speaker. 3. Try "bad" speaker at another IP location and see if noise follows speaker. Try a different "good" speaker at "bad speaker location" and see if noise still happens at "bad" location. 4. Remove the bad speaker and replace it back. 5. If even with this verification and adjustments the speaker sounds bad, test the individual speaker with the audio files provided in the Service Library Homepage under "Reference Materials" prior to replacement. Follow all these steps, if issue still happens; reach out to the engineer at Stellantis for more support, if the engineer doesn t respond in 30 minutes. Then the speaker can be replaced.
