Any chance you could give some tips on the audio upgrade, I have added the sub package but not sure where to go with upgrading the door speakers. Unfortunately there's no chance my Indiana car will make it to California for just an audio upgrade.
Thanks for the kind comment. "Refining Teslas is more than just a business for T Sportline. The attention to detail and the love for all that is special and unique about Tesla Motors is what drives us to produce out of the ordinary Model S’ and Model X’s."
