i thought 95-97 was all the Harmon Kardon systems? i know at least some of the X300 says Harmon Kardon on the speakers. Then they went back to Alpine in 98. My dads 2000 XJR had complete Alpine factory stereo.

 

^ i think ALpine makes the best headunits, you can buy a middle of the line high quality Alpine headunit for right about $150, almost all of the 07 newer models have integrated Ipod interface and all you need to do is buy the ipod cable... i took my alpine out of my last car and am contemplating installing it. i saw a x300 with an alpine installed - it was recessed in a couple inches from where the factory one sits flush and had a custom surround - it looked just fine.

sound quality will increase imensely with a nice modern Alpine headun.
