wire strippers
electrical tape
phillips screwdriver(+ shape in case you call it something else)
installing them is pretty simple. remove screws, remove old speaker, cut wires loose, attach wires to new speaker, put in new speaker, put in screws.
the only thing about the wire part is you don't want to let them touch each other or metal. as soon as you cut them loose put electrical tape around the exposed wire so it can't touch anything.
you can also pull you battery to avoid that but its easier just to take that 2 seconds to put tape on the cut wire until you're ready to hook it up.
