If you are cheap like me you can get the amp and speaker by butchering pc speakers. I have built a few with them and used the amp but the low watt speaker is pretty loud all by its self. Most pc speakers only run 4 of 5 watts without spending mutch you can get a pair of them on ebay and i have hade good luck with them. I almost forgot you must make a box to get the sound out of it i make mine with cardboard and hot glue.
