I just heard from Cliff at Reus Audio. You may have heard about them or read about them on the forum, but owners have been very happy with the sound upgrades they have done to Tesla's. I have never used them, but being dissatisfied with the stock (and premium) Tesla Audio, I figured I would give them a try. They are coming to Chicago 6/18 or 6/19 to do installs. The more people who get it done, the less expensive it is for everyone. If you are interested, please contact Cliff asap at [email protected] or 714-633-6636 Again, I have nothing to do with them and can't answer any questions about their service, just thought it might be beneficial for everyone to have more done at once.
