I have a very old receiver. A Sony STRDE475. http://www.iq.sony.com/srvs/DocsConnect/docget.asp?manualid=11637&DL=', ( I think that link works) The receiver came with speakers but instead of those speakers I am wondering if I can hook up my klipsch computer speakers to the receiver instead. Then vice versa use the speakers that came with the receiver on my computer via the klipsch sub. The Receiver says output is 80watts per channel. The information on the Klipsch sound system is kinda sketchy. I couldn't find much besides that the unit puts out 400w. Now I'm just a noob to this but wouldn't this mean the receiver puts out 400watts (5 channels [80watt per channel]+ sub) So if it puts out the same wattage as the Klipsch sub then I'm good right? No worries about turning it up too loud and blowing the speakers.
