I also reached out to them about a month ago. They are supposed to be a great shop but I have no first hand knowledge. They took a couple weeks to return my email (website says email is the best way to contact them!). They said they hadn't done any systems in a model 3 yet and wanted me to contact them about building a system for my car. Unfortunately, I don't want to drop $5k or more on a system nor can I leave the car with them for weeks to R&D a system. I was just hoping to have a sub built and maybe some speakers to supplement what is already in there. FWIW, I never got back to them. Was hoping they'd already worked on a 3.
