I have what sounds like the same rattle, and I have a soft top. I have not been able to get the latches right above the front seats to align properly, but the rattle definitely sounds passenger. It sounds like it’s coming further to the back. I only really notice when I am off reading or hitting rough road. I was thinking it was the soft top lowering mechanism hitting the back support bar, but I was not to see any thing that was loose when riding in the back seat.
