What brand is the original audio system in the Audi S4?

Audi S4 premium audio experience upgraded with the original German B&O audio system. Here are the specific details about the Audi S4 audio system: Output power: Most current head units indicate music power, typically between 40W60W, and the power should not be too high. Frequency response: The human ear can hear frequencies ranging from 20Hz20KHz, so this specification should at least cover this range, and the wider the better. Signal-to-noise ratio: This refers to the ratio of music signal to noise. High-end car audio systems generally have a ratio above 90DB, and the higher this value, the better. Total harmonic distortion (THD): This indicator reflects the fidelity of sound reproduction. The lower the value, the higher the fidelity, and the better the audio performance.

I've driven quite a few cars, and the Audi S4 comes standard with a Bose audio system, which is pretty common in its class. As a performance vehicle, the sound tuning has a sporty feel—clear and powerful audio with particularly impressive bass, perfect for listening to music at high speeds. Bose and Audi have collaborated for years, so the integration is seamless, with speakers strategically placed in the doors and dashboard to minimize noise interference while driving. Personally, I find rock or electronic music especially thrilling in the S4. The system also supports multiple connections like Bluetooth or CarPlay. If you're considering an upgrade, some versions offer Bang & Olufsen, but the base Bose system is already satisfying. Overall, Audi doesn’t cut corners on audio, and it really enhances the driving experience.

Once I rented an Audi S4, and what impressed me most was the performance of the factory-installed Bose sound system. The audio quality was rich and detailed—listening to music on the highway felt like being at a concert. The Bose system balanced highs and lows perfectly, with no interference or distortion, and integrated seamlessly into the interior. As an average user, I appreciated not having to tweak the settings—the default tuning was already excellent. Audi’s choice of Bose for the S4 wasn’t accidental; their brand partnership ensures reliability and consistent sound quality. If you test-drive it, you’ll notice it outperforms most standard car audio systems, making it ideal for daily commutes or long trips. Occasionally, I see discussions about upgraded versions in forums, but I believe the standard setup is already a great value.
