If you fit Co-axials in the dash watch out for the tweeters fouling the grills. I had this problem when I got mine so I cut the grills (which is a bit of a bodge!) Im getting some new grills when I get some Fusion 10cm components and mounting the tweeters in the doors. As for 6x9's, dont get me started! I hate the bloody things! They are just awful speakers, they mess with the bass from a sub in the boot (if you have one) and sound terrible when people cut into the standard parcel force. Your better off just getting the jigsaw out and cutting the rear armrest things (where the ashtray is) This makes a good mount as its a good size behind for small speakers and (with the aid of sound deadening) can sound quite good. I've also got some 10cm Co-axials in there. These are much better for rear fill as they dont dominate the sound as 6x9's do.
