Hi Model S Community! I recently purchased a used 2016 85D Model S directly from Tesla and the first thing I noticed was the poor audio quality (bass especially) in comparison to my 2009 BMW 650i. I was wondering if anyone has ever upgraded the sound system directly through Tesla or if they offer this service? I'm concerned to have after-market sound system changes external from Tesla since I can foresee that this will be a complicated process for EVs due to power management limitations. Any tips would be much appreciated. Thank you so much!
