What would I need to do to amplify the headphone output of the uMP3 to drive a single external 8 ohm speaker? This is a speaker from a stereo, it is rated at 8 ohms and 25 watt rms.

thanks
andrew

    Try using an LM386.

    The easiest thing to do is get an inexpensive set of amplified PC speakers; you can find them anywhere.
