What you need is an amplifier, not a power supply. Just don't exceed the wattage rating of the speakers (that should be indicated somewhere on the speakers) and it should work.

I couldn't begin to tell you how to build an amp. You can do a search for instructions or do what I would do and buy one for 25 or thirty dollars. The parts to build one would probably cost near that.
