What is the reason for no sound from the two speakers at the back of the car?

When there is no sound from the two speakers at the back of the car, the first step is to confirm whether this configuration includes speaker installations in the rear doors. If speakers are installed but not producing sound, it might be an issue with the channel adjustment. If neither of these is the case, then the problem could be with the speakers themselves or poor contact, requiring an inspection and repair at a 4S shop. Below is more information about car audio systems: 1. Introduction: Car audio (auto-audio) is a device installed to alleviate the monotony of travel for drivers and passengers. Initially, car AM radios were used, followed by AM/FM radios, tape players, and later CD players and digital audio systems compatible with DCC and DAT. 2. Components: The car audio system mainly consists of three parts: the head unit, speakers, and amplifiers, which are the most important components of the system. 3. Issues to note when modifying the audio system: The primary concern when modifying a car audio system is the electrical circuit. It is essential to go to a professional modification shop for any modifications or repairs to avoid damaging the original car circuit, affecting the vehicle warranty, and to ensure proper after-sales service. During installation, power cables, audio cables, and signal cables should be routed separately, with proper shielding and protection between the lines.
As an experienced driver, I've encountered situations where the rear speakers suddenly stop working, and there could be several reasons for this. The most common issue is that the rear speakers themselves are damaged, as audio units are prone to aging due to constant vibration and volume fluctuations over time—lights may be on but no sound comes out. Another possibility is wiring connection problems, such as loose or corroded plugs, preventing signal transmission. Additionally, it's worth checking the audio settings: press the balance button on the car's infotainment panel, as the settings might be biased towards the front or the rear audio source might be disabled. If none of these issues are present, it could be a blown fuse or a fault in the head unit affecting specific channel outputs. If you notice this problem while driving, avoid operating the audio system immediately; instead, find a safe place to stop and check. Distractions can easily lead to accidents. If you can't resolve it yourself, promptly visit a reliable repair shop for diagnosis and repair.
