Rob, did you lay down the jute or some sort of underlayment? Amazing how much carpet and jute quiets the ride from rubber mats. When I got my carpet, the guy sent a 25 lb roll of some sort of black pliable linoleum looking stuff. It laid down flat and I was able to form it into the corners and over the hump for a flat finish. Not real happy about another 25 lbs but it sure is quiet down there now.
