The noise is probably dust as Adamou said, either clean it or replace it. Sometimes you'll need to replace it, as dust gets into the voicecoil underneath the tweeter (if coaxial), which the turns the ferrofluid into a sort of abrasive porrige which given time will kill the tweeter.

Removal is as John said, except there are 2 philips screws. (John, I think you're missing one!!). To remove the speakers is tricky... you need 6 hands and a lot of patience. I took the easy route... I removed everything from the area and jigsawed the old speakers out! Not recommended tho if you want to use the old mounted holes :-)

Good luck

Brian
