Difference lies in the noticeable variation in audio-visual effects. Comparison between Audi A3 standard audio and BO sound system: 1. Audio Experience: A simple analogy would be that the standard audio performs like built-in TV speakers, whereas the BO sound system delivers a home theater-like experience. Superior sound quality significantly enhances the audio-visual sensation. 2. Price Difference: The gap is 6,000 RMB. The vehicle comes equipped with standard audio by default, while the BO sound system requires post-purchase installation. Opting for factory-installed BO audio during vehicle purchase yields far better results compared to aftermarket modifications. All Audi A3 models are fitted with standard audio systems. For those prioritizing premium sound quality, BO sound system can be directly installed at authorized 4S dealerships.

When I was buying a car, I specifically compared the standard audio system of the A3 with the B&O option. The standard system only has 6 speakers, and the sound feels thin, with the bass somewhat floating and the highs not clear enough—it tends to distort at higher volumes. The B&O system comes with 16 speakers and an independent amplifier. As soon as you turn it on, it feels like bringing a live band into the car—full and rich, with every detail crystal clear, even the drum beats resonate deeply. For audiophiles, it's absolutely worth the extra over 10,000 yuan, but if you're on a tight budget, you might need to think twice. The overall ambiance upgrade after choosing this option is massive.

From a hardware perspective, the A3's standard audio system is a basic configuration with fewer speakers, lower power output, and mediocre sound quality. The B&O upgrade adds high-density material drivers and a digital signal processor, doubling the power to deliver a surround sound effect. Even road noise can't mask its refinement—especially when listening to vocals, it feels as if the singer is sitting right beside you. However, this upgrade doesn't come cheap, costing an extra 10,000 yuan. For daily commuting, the standard audio system is usually sufficient.

I have no problem using the regular audio system for daily commutes. It plays pop songs loud enough but lacks refinement, and the navigation voice is clear. The B&O system adds more speakers and tuning functions, providing a stronger surround sound experience with solid bass that doesn't distort. It's great for relaxing on long highway trips, but the installation cost is significantly higher—the money saved could cover half a year's fuel expenses.
