New to club and new to site. Just purchased 98 z-3 and am looking to replace speaker system with upgraded one. Would like to find the good system that would be least intrusive to install. Local dealer will sell OEM, however technology now should keep hair blowing straight back. Also anyone who has done this, and could give info on how to install, remove grills, door panels etc. would be helpful.
See if these guys can help you out: http://www.bavariansoundwerks.com/ Bentley Manual: http://www.bentleypublishers.com/bmw/z3-series/z3/1996-2002/ You may want to also connect with the Z-club, listed here: http://www.bmwcca.org/chapters/specialgroups Congrats on the Z, welcome to the club & the forums!
The Bavarian SoundWerks site includes links to videos so you can see what it takes to put, say, a DICE unit in a Z4.
