But I think my disappointment with the system is with its fidelity, the subwoofer actually gives off good clean bass, but the overall sound quality can be improved. I noticed that the system now sounds better than 3 weeks ago, perhaps it's the speakers finally breaking-in, if there is such a thing, I hope it keeps improving.

Eric--I noticed you said you thought the premium sound system could be better. Have you by any chance tried to look at the factory subwoofer in the rear parcel shelf? I am wondering if it might be pretty easy to replace it with something with more "oomph" to it.
