2022-2025 Stellantis Door Speaker No Sound TSB

Symptoms

Owners of 2022-2025 Stellantis vehicles equipped with Premium Audio Systems may report that their door speakers appear "inoperative or no sound." This often stems from the perception that the speakers are not functioning because they do not produce sounds in the vocal range.

Diagnosis / Trigger Conditions

The primary reason for the perceived "door speaker inoperative or no sound" issue is the specific design of the door woofers in Premium Audio Systems. These speakers are engineered to reproduce only low-frequency (bass) tones. Consequently, customers might mistakenly believe the speakers are not working when they simply aren't producing mid-range or high-frequency sounds.

To accurately diagnose whether a door speaker is genuinely faulty, Stellantis STAR Online Publication S258A000017 recommends using specific audio test files. The 80Hz MP3 audio test file is crucial for verifying the proper operation of the door woofer speakers. This diagnostic method helps differentiate between a speaker functioning as intended for bass frequencies and one that is truly non-operational.

Repair Procedure Summary

Stellantis STAR Online Publication S258A000017 outlines a clear diagnostic procedure to confirm the functionality of door speakers in vehicles with Premium Audio Systems. This process helps address concerns about a "door speaker inoperative or no sound" condition. The steps are as follows:

1. Download Audio Test Files: Obtain the necessary MP3 audio test files, specifically the "80Hz Audio Test File.mp3," and transfer it to a USB drive. Other available test files include various Hz frequencies (40Hz, 43Hz, 46Hz, 49Hz, 52Hz, 55Hz, 58Hz, 61Hz, 64Hz, 67Hz, 70Hz, 73Hz, 76Hz, 79Hz) and a "Test Signal for Harman Amps.mp3" for comprehensive testing.
2. Insert USB Drive: Plug the USB drive containing the audio test files into the vehicle's radio system.
3. Play 80Hz Tone: Play the 80Hz audio track through the vehicle's sound system. Listen carefully for the tone emanating from the door speakers.
4. Evaluate Speaker Function: If a clear 80Hz tone is audible without any unusual noise, the door speaker is functioning correctly as designed. Conversely, if no sound is produced from the door speaker, it indicates that the speaker is indeed non-operational or inoperative.

This diagnostic guidance applies to all Stellantis vehicles equipped with an external audio amplifier as part of their Premium Audio System.
