1996 century remove dash speakers

I want to replace my dash speakers, how do I get to them?

you should be able to remove the vent cover with a small flat head screwdriver, but be carefull or you will break them like i did, then you will need to use aabout an 8m ratchet (not quite sure about the size) and remove the bolts from the speakers, they are 4"x6" speakers
