WoW!!! It really sounds good. I drove all over the place tonight listening to it and the sound brings a huge smile to my face. Now I know why everyone recommends it. I stopped off at my girlfriends condo and I think it set off a car alarm in the underground garage. Cannot wait to drive through some tunnels. Thanks FOBH & Giovanni, very clean and quick install. They also updated my software which is supposed to help cold starts.
