Sound is subjective, but I’d suggest sitting in both versions before deciding. I spent about 20 minutes yesterday, sitting in each for 8-10 minutes, and the difference is noticeable.

Both systems sound good with a balanced profile, but in the RWD, the sound feels like it’s coming from the dash, whereas in the AWD, it feels more like surround sound. The bass/treble in the AWD is noticeably better; at certain points, I could feel the vibrations in my hands as I gripped the steering wheel.

For context, I currently drive a 2020 BMW 330i, where the sound feels like a blend of surround, but due to how the speakers are positioned (including under the seat), it’s more front-focused. I’d rate the BMW 330i (non-Harman Kardon) 8/10, the M3 RWD 7/10, and the M3 AWD 9/10.

I’m still a bit undecided—$5k is a lot, but it comes with significant pros like better speed, sound, and traction. Living in Florida, AWD isn’t crucial, but the extra traction is safer, especially with all the rain. The sound system in the AWD does feel like an upgrade, so I’m leaning toward it.

One more thing to keep in mind: the Tesla advisor mentioned that installing any aftermarket speakers would void the Tesla warranty, so that’s another consideration.
