The door panels come of with common tools but there aren't any direct drop in speakers to replace yours. It will take some work as the woofer is not standard size. Are you planning on adding some new/more amplification? This is one of the weak spots of the stock system. I wouls recommend a professional installation because it can get complicated if you don't have a lot of experience with car audio.
