I ride with "Lee" on the 2A, he has a 2A... His is quite a bit quieter than my 3A and both are similarly broken in and set up. He has a set of medium density rubber floor mats that cover the floor on both sides and the transmission tunnel. I asked him to remove it for a ride one day and we discovered that with the matt out his jeep was about the same in noise and heat that mine was, with it installed it was much different. As a result I put a cow matt in the rear of mine. Those are from Tractor Supply and are about 3/4 inch thick heavy density rubber. Up front I don't have anything yet, working on that as it seems like a good way to go.
