the wire usually is very obviously soldered to two leads on the base of the actual internal speaker and is "really easy" to replace (naturally depends on the particular speaker). make sure to keep black and red on the proper leads. (as far as I know, wiring it backwards still works, but the sound will be weakened or something.)

the harder part is probably the other end with the plug. you need to either splice the new wire to the old plug, or onto a new plug (or maybe you have wire that already ends in a plug). as long as you replace the part of the wire that has the break, and solder it properly with no shorts, this will very very likely solve the problem.

a speaker that just doesn't work even with a replaced wire is not something I've ever seen or heard of. I've seen speakers that are basically torn in half still work, they just sound terrible. I think the actual speaker mechanism is simple enough that it's very unlikely for it to fail. (not an audio or electronics expert by any means though.)
