What Audio System Comes Standard in BMW?
1 Answers
BMW utilizes audio systems from Harman Kardon in the USA and B&O (Bang & Olufsen) from Denmark. Here is some extended information: 1. Harman Kardon and B&O: Harman Kardon is a division of Harman International Industries (NYSE: HAR), specializing in the production of home and automotive audio systems, headquartered in Woodbury, New York, USA. Brands such as JBL, AKG, and Infinity also fall under the Harman group. Harman/Kardon was founded in 1953 by Dr. Sidney Harman and Bernard Kardon, both passionate about music and art. B&O (Bang & Olufsen), produced in Denmark, is renowned for its aesthetically pleasing audio equipment. Denmark is also the country with the highest number of audio brands globally, with approximately one brand per 250,000 people. 2. Precautions: The temperature inside a car can get very high, so it is recommended not to turn the audio volume too loud. Doing so not only affects the sound quality but also reduces the lifespan of the audio system. Additionally, the mechanical parts consist of a combination of metal and plastic components integrated with circuit boards. Metals and plastics have different specific heat capacities, meaning they react differently to temperature changes. When the car interior is very hot, be patient when changing CDs—let the system operate automatically without forcing it. For multi-disc changers, avoid repeatedly pressing the disc change button; allow the system to control the process automatically. External high-power amplifiers are even more sensitive to temperature changes and require substantial heat dissipation. Therefore, during summer, ensure that any external amplifiers are well-ventilated when the audio system is in use.
