Car audio is the only excuse for the compression used in so many recordings. When the noise floor is that high you can't get another 80db without damaging your hearing. Ask how I know.
Years ago I used dbx for noise reduction on tapes and had a car deck with a dbx expander add-on. Discovered that in the car, many dbx recordings were better left unexpanded because you could then hear the sounds normally obscured by the noise floor.
