Why is one side of the Atenza's audio system not working?

Atenza's audio system having sound on one side but not the other is an audio malfunction. The following are specific introductions about the Atenza: 1. Configuration: The new car comes standard with intelligent idle stop system and brake energy recovery system. The Atenza 2.5L model accelerates from 0 to 100 km/h in just 8.3 seconds, with a minimum comprehensive fuel consumption of 6.9 liters per 100 km, while the 2.0L model's comprehensive fuel consumption is only 6.3 liters per 100 km. 2. Appearance: It adopts Mazda's KODO design philosophy, with a U-shaped front face and LED headlights, giving it a stronger sporty feel. The new car introduces an 11-speaker audio system. Compared to the previous generation Mazda6, the Atenza's wheelbase has been increased by 105mm, providing more spacious rear seating. The Atenza uses the SKYACTIV chassis technology, equipped with high-performance MacPherson independent front suspension + multi-link independent rear suspension. Through structural optimization, it achieves both weight reduction and increased rigidity.
Last time my Mazda Atenza also encountered this issue, and I was really worried at that time. Later I found out the most common cause is poor contact in the door speakers, where prolonged vibration causes the wiring to loosen. You can even check the connectors by poking the speaker cover with a toothpick. Another possibility is a damaged crossover, which requires removing the door panel to inspect. Additionally, a faulty channel in the head unit amplifier can also cause sound loss on one side—you can locate the problem by playing music through different channels. In my case, it was a burnt speaker coil, and replacing it with a set of domestic speakers only cost 300 yuan. I suggest not rushing to the 4S dealership to get overcharged; it's more cost-effective to have it checked at a professional car audio modification shop.
