How many speakers does the BMW E90 have?
2 Answers
BMW E90 has six speakers. Methods to maintain speaker appearance cleanliness: Ensure all wiring connections are secure. Regularly inspect and tighten the fixing screws of the speakers and brackets to ensure reliable grounding. Speaker mounting methods: The mounting method of the speaker significantly affects its sound output. To ensure normal sound production, speakers should not be rigidly mounted. Instead, they should be fixed on a vibration-damping bracket, meaning a leaf spring or rubber pad should be installed between the speaker and the mounting bracket. Checking generator output voltage: Excessive voltage can burn out the speaker contacts, while insufficient voltage (below the speaker's rated voltage) will cause abnormal sounds from the speaker.
My car is an E90, which I've driven for over five years. The audio system comes in different configurations. The standard version only has six speakers: four in the front (one mid-range and one tweeter on each door) and two coaxial speakers on the rear doors. If you opt for the top-tier Harman Kardon package, there's an additional center speaker in the dashboard and a small subwoofer hidden under the rear windshield, bringing the total to thirteen speakers. When buying the car, you need to check the configuration sheet—mine is the standard version, and the speaker quality is indeed average. A friend spent over 10,000 yuan to upgrade to a full Harman Kardon system, and the surround sound effect is absolutely amazing.
