What Brand of Audio System Does the BMW 3 Series Use?
1 Answers
BMW 3 Series uses Harman Kardon audio systems. Harman Kardon is a division of Harman International Industries, specializing in the production of home and car audio systems. Below are some maintenance tips for the BMW 3 Series audio system: 1. The main unit is particularly susceptible to weather conditions, especially the circuit board and plastic components. The parameters of electronic components on the circuit board vary with temperature changes. Therefore, if the car's interior temperature is high, it is advisable not to turn the volume up too high, as this can affect both the sound quality and the lifespan of the audio system. 2. The mechanical part consists of metal and plastic components combined with a circuit board. Since metal and plastic have different specific heat capacities, they react differently to temperature changes. When the interior temperature is high, avoid rushing when changing CD discs—let the system operate automatically without forcing it. For multi-disc changers, refrain from repeatedly pressing the disc change button and allow the system to control the process automatically. 3. External high-power amplifiers are more sensitive to temperature changes and require substantial heat dissipation. During summer, ensure that external amplifiers are well-ventilated when the audio system is in use. 4. Summer is often rainy, leading to higher humidity. The main unit and discs are most affected by humidity. Always clean discs thoroughly before inserting them, wiping gently from the center outward. 5. The speaker cones are the most temperature-sensitive part of the speakers, directly impacting sound quality, especially in the mid-to-low frequency range. It is recommended to recalibrate the audio system during extreme temperatures.
