How can i remove the front speakers in a ford festiva?

I bought new speakers for my 2000 ford festiva, and cant work out how to actually get the door card off to get to the speakers!How can i remove the front speakers in a ford festiva?Ok first look to see if you have any screws holding it if not then there should be like little thumb tack things holding it, in that case your going to have to pull the panel with a little elbow grease now I'm not shore but those are the 2 ways i know it so i guess give it a try.
