I would not expect it to sound any different at all. It's going to be pretty much the same since you will have the same 20 year old speakers in the car. Basically an expensive radio for keeping the Porsche name on it.

Unless you replace the speakers & amp no radio is going to sound better then what is original. Plus it's a convertible so it's never going to sound all that great to begin with.
