Golf Mk IV stock speakers

i've bought some new speakers for the front of my 2003 Golf. I've taken the door panels off but when i finally get to the speakers they are pot rivetted in. Can anyone explain an easy way of removing them?

Any help will be appreciated, thanks

If its pot rivetted you should be able to just use a chisel and hammer and pop the rivets with that, just make sure you get a very thin chisel, you can subsute a screwdriver if you dont mind damagine the screwdriver

Just A thought
