Truthfully, to everyone hooking up thier speakers to their AV system, i highly reccomend running it through your computer, if it doesn't have seperate pre outs. Look on the back of your reciever for a "tape out" connection (also can be labeled "record" "tape record" ...ect) use a standard 2 rca male to stereo 1/8" then just hook up the 1/8th" connector to your computer soundcard (Line in or mic in...but if you use mic in be sure to disable the 20db boost). Also, after you have done this be sure that the input you used on your computer is enabled (if you do not see it listed in windows sound mixer go to "options" then "properties" then put a check next to the correct input, or look in the control panel for "sounds and multimedia" then the "audio" tab then click the "volume" and repeat the previously mentioned process.). After this, you will want to set the input level...probably to around 2/3rd but this can vary greatly depending on the output of your reciever the only main disadvantage of this is your computer will need to be on for it to work. After you have set it up go to the control panel and set It should however provide you the best audio quality with the least amount of wire hacking. If anyone wants to use this method and has any more questions please PM me about it and i will post it back in here (as i will probably not be rechecking this thread often).
Hope this helps.

(BTW, line level converters are about $20 for a stereo signal and you will need 2 of them, and radio shack has decent speaker cable fairly cheap....look for a good quality 14 guage cable which you can buy on a spool.)
