Just fitted a set of the 6500's, bloody sweet they are too.
Only problem is that they're a bit lacking in the old bass department. Not sure if we've got a problem with our setup or if they just need to be backed up by a sub. Bit concerned that we're only running them from the OE kenwood cd player, might not be kicking out enough juice for them.
They really are cracking speakers, just forget ever listening to MP3 sourced stuff woth them though, they show up every digital artifact like you wouldn't believe, right pain in the arse.
