There is a good guide for this in the FAQ section under removing interior bits. If you stick
to 6.5" fronts you won't need to remove the speaker grills. The grills are part of the door
trim and not directly attached to the speakers. The rears are all ready 6x9's but when I
upgraded mine I had to enlarge the cut out slightly. I'm sure you could fit 8" in the doors
if are prepared to put the effort into it. For a 6.5" you'll have about 70-75mm of depth to
play with. This may be less for an 8 which may foul the metal door skin so you'll need to
take the door trim out and measure up to be sure. Removing the door trim is simple and
quick.
