If you want great sound with no frills or a terrible boom at highway speeds, this is for you. The delivery was incredibly fast. I installed it so can't tell how difficult it is, but the installer said it wasn't difficult with a lift. It just sounds good. At speed on the Autobahn you hear a little more than at the factory, but you can still talk, make phone calls, drive hungover (laughs). etc. without being disruptive.
