Cheers guys.
Paul, haven't bought them yet, going on the assumption of using flush mounted hardware.
Dano, no electric mirrors, otherwise I would have!
Jay, did you have them up there in your old IS?
For anyone interested, looking at Pioneer TS-A1702C's, can get them for about $160 on ebay. Autobarn / JB etc want $260-290!
Found the Alpine SD series 6.5" components have a tweeter that is WAY too bright, German Maestro (original MB Quart so i'm told) AS608's sound nice, but looking at $240 a set...
Anyone else got any suggestions for a decent set of 6.5" components under $200?
