The front speakers were pretty easy to do (as per TSN.00Z's instructions), but I did have trouble getting speakers with grunt to fit the hole size.
I ended up with 40W being the maximum speaker in that size.
The speaker mounts are little plastic speaker boxes, presumably to add a bit of Bass to the small speakers, and I had to cut into the drivers side one (from memory) to get the new speakers to fit in to the mount shape of the speaker box, as they had different mounting lugs.
I also lined the part where the speaker mounts to the box with 3mm foam tape to prevent any buzzes & to seal the box up again.
I may even mount a little subwoofer somewhere under the centre console if I can find one small enough - just to get a bit more "doof" in my doof doof, as there's not much bass in the system.
As for the radio, I replaced mine ASAP as the only thing I could pick up was christian radio. After a few weeks of listening to that I was almost ready to circumsize myself!
