I would prefer that the 9500i be a tiny bit louder....my 8500 was louder I think. I was at a truck stop today and picked up a sort of CB extension speaker with a mini plug on it for $9.00. It is surprising solid and made of metal. When I plugged that into the 9500i and powered on you could really hear it (like in the car next to me you could hear it). I may try to mount that out of the way and thread the cord down thru the smart cord.
