Ok. I know next to nothing about car audio, but I'm interested in making an upgrade of the Bose system in my 2003 Z. For the record, it's the "premium" system with the 6-CD changer and the sub, etc.
I'm seriously looking at the Alpine CDA-9815 for my head unit, probably with the CHA-S634 CD changer unit and the TUA-T020XM unit so I can plug in the XM. But after that, I'm totally lost in terms of what kinds of speakers, etc., to go with.
I'd greatly appreciate any advice anyone feels comfortable giving.
Thanks.
