Have you set the bass, trebble, and mid for the satellite radio? Each audio source retains separate settings, so if for example you like your music a bit brite and have high trebble for FM and CD you will also need to set it that way for Satellite. Otherwise it would seem flat.
Might not be this at all, and pretty soon I will have mine installed and find out for myself. Just a thought.
