I'm seriously disappointed with my sound system in my 2017 S. I was too impatient to order a car so I settled for one on the lot last month that didn't have the premium interior package, but DID have the ultra high fidelity sound package that I really wanted. I was decently happy with the performance of my demo test drive vehicle that had both, so I had to have that option while settling for not getting premium. Since delivery, I'm completely unimpressed with the sound. The sound is not crisp. The door panels make the car sound like a cheap economy car sound system. Even the amplification seems weak. I've had a loaner 2015 P85D with premium and ultra high fidelity and it sounds like I expected. So, has anyone else experienced this and have you been able to get Tesla to do anything about it? I feel like I've gotten cheated in many ways since delivery--60 sec time reduction, standard Air suspension, premium lighting, etc. And now this having paid the extra $2500 for a system that sounds like crap. Thanks for the help. Sorry to complain!
