Yeah, they did say premium at the Flagstaff event and referenced Audi in some video's I watched as a comparison.
I always am leery about truck audio systems and they're speaker arrangement. A great (not just good) sound system is crucial for EV's with they're near silent operation.
I'd be hoping for like at least a 12 speaker set up, with 2 speakers per door, 1 for each a-post, a center channel speaker and sub under the seats. But again the more the better.
