Probably the cheapest, simplest way. 2 x 10 watts. You might need to make a small mod or two to get good low frequency response, but it's easier than building from scratch and it's well documented on the web. Or look for a small car stereo amp on e-bay. Steve at ApexJr. also has a 25 watt car amp for cheap.
Listen to the music through the stereo, not the stereo through the music.
