I have an 1980 and a 1987. the speaker mounting is different. The 80 mounts on to the metal of the door -- those pre drilled. the 87 mounts to the panel itself.

I think the mounting changed some time in the mid 80s. Also the factory grills changed. In my 80 the almost flush surface mounted grills are secured with plastic pins that are held to the panel with circlip type washers. Removing the grill is not possible without removing the entire panel. If you force it, the plastic pins break off.


The later style grills push on to the mounting metal backing of the speaker.

This is the later model stock grill mounting --- "above the surface"

So when I changed the speakers in my 80, I took off the panel and attached the speakers to the metal of the door and kept the original look with the original flat grills.

When I changed the speakers on my 87< I did what is shown in that post. Cut out the old speaker and used that old metal frame, putting it behind the new speaker so I could snapfit the original grills to the frame.

You may want to do some creative mounting. The later 240s, I think 90, 91 and on came with larger door speakers, 5 1/4" rather than the 4" in the 80s series.

If you want to keep the stock look then you can't get larger than 4" and the depth specs limit your choices to very few.


One possibility is to just put a tweeter up front and install larger speakers on the rear deck. There, if you don't want to cut metal, you can use above surface mounts and just run the wires up from the trunk to the rears.


I've got 4 speakers in my 80 sedan---6" ones in the rear deck. The prev owner had cut larger holes in the rear deck, so that job was done.
