I had a bit of a problem fitting the Mike Satur 'FX' speaker grills whilst using the original speakers, so I thought this may help if anyone else want's to go down the same route
The main speaker is easy, just cut the 3 lugs that hold the original speaker grills at the back and remove:
Put the new grill bolts in the original holes. I had to enlarge the holes slightly as the bolts don't quite match up:
Now comes the tricky part if, like me, you want to use the exising tweeters. You need to recess the tweeter to allow fitment of the new grill. First remove the original tweeter by unplugging and then unscrewing the ring on the back of the tweeter:
Screw in the 6 bolts to the FX speaker grill:
Use this to mark the position for the corresponding holes in the door card and drill the holes, ensuring the 'FX' is aligned correctly before drilling!
Remove the tweeter cover and dremel notches in the orignal tweeter surround to match up with the bolts. This allows the speaker to fit within the bolts. Don't over do the notches, you want a nice tight fit between the bolts. As you can see in the photo I had to have 2 goes to get the notches right on the first tweeter
:
Using the original plastic ring as a template for the inner hole make a ring out of a suitable material (I used some spare hardboard). The ring needs to be big enough to take holes for the 6 bolts and the hole must fit tightly over the threaded rear of the tweeter (you can discard the original plastic ring):
Now fix the speaker cover with appropriate washers and nuts:
Place the tweeter betwen the mounting bolts:
Finally put the ring onto the bolts and affix with some more washers and nuts:
Your doorcard will now look like this
