[sdiy] impedence stuff???

[Dr Strangelove]

Yea, the speak and spell and the casio sk1 aren't driving big speakers.  
Like the little amp that drives passive speakers from a PCs sound card.  I 
usually leave that amp switched "off", but I have it on right now, because I 
was trying some passive PC speakers (read: crap).  I am currently driving my 
stereo's aux in from that signal with no ill effects.  The signal doesn't 
even seem that hot.
