Correct...take s screw driver and put tape around it so you won't scratch the cover when you pry the mesh off. Once this is off, you'll see the 3, or was it 4 screws that come out to take the speaker out. The wiring is a quick connect plastic piece...very easy. Now, the question is where to get another speaker. I would first try a yard, like http://www.erievovo.com/ If you still can't find one then the dealer it is...what I had to do when I had one go bad...a few years ago, they were about $35 or $40 each. I wouldn't try to put a different speaker in there unless you're changing the other one too and the Ohms match.
