What sizes of speakers could I fit in the front and rear of a '87 FC GXL, and what happend to my center console? The power mirror control isnt working, along with the clock, cigarette lighter, and suspension setting.

 

4 inch in both front and back.....but the for the rear you can get adapters to allow a whopping 6 1/2!!!!
as for the center console, i gess check the connectors under the switches by prying up the plate that houses the switches
the clock probably needs resoldered

 

Where can you get the adapters at?

 

If you check www.crutchfield.com they have adapters that will let you use 6 1/2's in the back. They're cheap, or free if you buy some speakers with them.

They're made of cheap plastic, but they work, can't ask for much more than that.
