Help removing front speakers
I hate to ask this, but my manuals are packed away because I relocated to Pennsylvania. BUT, is there a thread to show how to remove the front speakers on a 1993 C4 coupe? I checked both this forum and the C4 tech, but was unable to locate one.
My winter project is to send the front units to Dr. Don for referb.
Any photos or instrucions would be appreciated.
Thanks.

Fronts are easy.
You need to remove the Framerail cover (the carpeted one) runs the length of the door. There are 2 screws on the door side, seen with the door open, You may also (i usually do) remove the plastic trim at the back of the door above the carpeted piece.
the carpeted piece may be a bit stuck as there is some goop underneath but it should pull up and out..
The Front speakers are held in with 4 10mm bolts and then disconnect the harness and it it out

Update:
I spoke with Dr. Don, and one of the problems experienced by Corvette owners is replacing the factory units with generic units not EQ'd for that particular car's interior. This of course results in poor sound.
The fronts are EQ'd for highs and mids, while the rears are EQ'd for mids and lows. This particular Bose system was designed by Amar Bose himself, and this is documented in Corvettes From the Inside, by Dave McClellan.
Dr. Don said that the electrolytic capacitors leak and contaminate the amplifier board. As the caps weaken, sound degrades and power falls. Eventually, the caps are not strong enough to activate the speakers as they were designed to.
As for installing the wrong units: mine were the factory originals, and contained all the identifying data needed to determine the proper replacements. Year and make of car, position of speaker/amp and body type (vert or coupe). My Ruby now has 119,000 miles on it and it is of course thirteen years old...
