Door speakers rattle....need advice

Hey guys I was just wondering i've got a 2001 Civic LX and i'm looking to get a sound system in it. I don't like where the front speakers are mounted in the door and they rattle a good amount. I don't have a CD player yet, but i am getting one very soon. does anybody know if the CD player will help cut down on the rattling? i don't think so, and i was gunna get new speakers aswell. will the high quality new speakers help with teh rattling on the doors or am i pretty much screwed b/c of the way they put the speakers in the civics?? plz help, THANKS!
