In an effort to reuse what I have on hand, I've put together a box with two old computer speakers and a mid range loud speaker I have on hand. The idea behind this is to have a single self contained speaker cube to plug my mp3 player into using a 3.5mm. It's not going to sound amazing, but I hope it will sound decent. To complete the project, as I am not a great electronics tech, I am looking for an out of the box chip amp that I can simply plug the speakers into to give them enough power to make some noise. Any suggestions would be greatly appreciated.
