Quick question will replacing my standard radio in a 99 SLS with the Bose model show any better performance in sound or is there more to just replacing the standard head unit with a Bose unit?

There's more. More speakers and more importantly, a separate amp.

So Just buying a BOSE headunit is only part of what I need. So with the Bose system there are 2 amps behind the rear seat?

Do a search on the Bose unit. I will try and explain here. This is just what I remember from reading here. The Bose head unit is basically just a remote module. The real stereo is behind the rear seat, but, it does not have an internal amp. I have read that you can remove the Bose head unit, with it on, and still have the stereo play. Anyway, after the unit behind the seat, each speaker has it's own amp. So to switch from a non-Bose unit, to a Bose, you will need to purchase the entire set-up. I also believe that the wiring harness is not the same, but I may be wrong on this. Good luck
