What Causes the Trunk Speaker of Tango to Stop Working?
3 Answers
The reasons why the trunk speaker of Tango does not work include speaker wiring failure and speaker damage. The details are as follows: Speaker Wiring Failure: If there is a wiring failure inside the door speaker, the rear speaker will not produce sound when the audio system is turned on. The maintenance technician can identify the abnormal speaker by sound, remove the door inner panel, check whether the speaker wiring is loose, and use a multimeter to test the continuity of the speaker wiring to determine if there is a wiring failure. Repairing the speaker wiring can solve the problem. If the vehicle is under warranty, it can be handled for free at a 4S shop. Speaker Damage: In a new car, the speaker diaphragm is relatively hard. If the speaker volume is set too high, it can easily cause the diaphragm to break, resulting in abnormal sound from the speaker. The maintenance technician can identify the abnormal speaker by sound, and the speaker needs to be replaced. If the vehicle is under warranty, the speaker can be replaced for free at a 4S shop.
I had a similar issue with my car before. After struggling for a while, I found out it was a loose amplifier connector in the rear. The subwoofer in the Tango's trunk is particularly sensitive to poor wiring connections, especially on bumpy roads where vibrations can loosen the plugs. You might want to start by peeling back the trunk lining to check if the black square amplifier connector is securely plugged in. Another common issue is a blown fuse—look for the 15-amp mini fuse labeled 'AUDIO' or 'AMP' in the fuse box on the driver's side, pull it out, and check if the metal filament is broken. If both the connector and fuse are fine, then you might need to consider whether the amplifier module has overheated and burned out. In summer, the trunk temperature can reach up to 60°C, which is really damaging to electronic components. If the audio system has been modified, also pay attention to whether the shop did any improper wiring that could cause a short circuit.
If you find the subwoofer in the trunk has no sound, don’t rush to send it for repair. Try this first: After starting the engine, turn up the volume and feel the subwoofer’s casing for slight vibrations. If there’s vibration, it means the amplifier has signal output, and the issue might be a torn speaker cone or a stuck voice coil. If there’s no movement at all, check three things: In the car’s audio settings, see if the 'Sound Field Balance' was accidentally set to mute the rear speakers; turn off the engine, disconnect the negative battery terminal, and wait three minutes to reset the audio system; for older Tango models, also check if the optical fiber cable at the back of the head unit has come loose. Once, after a car wash, my audio stopped working—it turned out the car wash worker had tugged on the trunk wiring harness, and upon opening it, I found the harness clip was broken.
