i have a friend who is finishing his basement. he is not an audiophile (not even close, he has a 10 year old aiwa type shelf system as his stereo) he wants to know the absolute cheapest way to power 3 sets of speakers in his house (basement, kitchen, back yard) i was thinking of using his pc+receiver card and mp3s to be music source, and getting a multiple 2 channel amps or one big multichannel amp to push the power. what would be the absolute cheapest (i mean cheap cheap cheap) way of doing it. sound quality is not a big issue, but money is....thx in advance
