Weak sound in G9 Performance MY26
I picked up my Xpeng G9 Performance in February 2026. Before this, I owned a Tesla Model 3 Performance and a Model Y Performance, so this was quite a technology switch for me.
I genuinely like both brands — Tesla definitely does some things better, while Xpeng excels in other areas. Overall, I was mainly looking for increased comfort, and in that regard I feel the G9 delivers compared to the Model Y.
I’m quite passionate about audio quality. In my experience, Tesla’s sound systems in both cars I owned were surprisingly good “out of the box.” The G9, on paper, has an impressive premium audio system, but I’ve started to notice a few things I’d like to get feedback on from other owners:
- The system sounds really good at low to medium volumes, but it feels like there’s a ceiling around ~70% volume. Beyond that, the sound doesn’t really open up or scale further. I can still comfortably talk to a passenger at full volume, which was basically impossible in my Teslas.
- There seems to be a lack of deep, impactful bass even after adjusting the EQ to max bass settings.
- Spotify audio quality feels underwhelming in the built-in app, while oddly enough, apps like YouTube seem to deliver better sound quality.
- Dolby Atmos is advertised, but I’m not even sure which apps actually support it properly in practice.
I’d also really appreciate any tips on EQ settings — if anyone here has managed to dial in a setup they’re genuinely happy with, I’d love to try it out.
Curious to hear if others have had similar experiences or found any settings tweaks that improve things.
I'm currently on XOS 5.8.7.8905
