D'oh! This GameTrailers user has an easy way of increasing the volume of his PSP speakers ... with his bare hands! By placing his hands under the speakers, the sound waves bounce back up, instead of away from the listener. Wow! Simple science that gets great results. See it in action, and then try it for yourself.
