Your audio system sounds pretty groovy, man!  I myself bought a new Kenwood CD 45x4 watt player over a year ago.  I replaced my old Kenwood tape deck that had been serving me for ten years.  Just last month I finally replace my two 4"- 50 watt speakers in the front with two new 100 watt 4" Pioneer speakers and the old 6x9 Kenwood 100 watters with brand new 350 watt Pioneer 6x9s for a killer deal off of Ebay.  The sound is much more rich and crisp...although I feel that in the next two years or so I am going to get a much better deck and a nice subwoofer with a decent amplifier just for a better over all sound, especially since I do most of my music listening in my ride.
