buying/replacing dash speaker

[fab]

Any suggestions where I can buy a speaker to replace my existing dash speaker for my 00 boxster? I would like to replace only one. It sounds terrible. Is it easy to replace? Something like unscrew, unplug speaker wire and then plug speaker wire into new speaker and re screw.
Thanks

Do a search on this forum on speakers... MLegere posted the make and model of some speakers that should fit as he's unhappy with his sound system as well. I think he posted it about two weeks ago.
