I need to wire up some surround speakers at home. I already have mains and center wired with Monster cable, and have the sub taken care of too. However, I dont have my rear speakers wired yet....which is where I need your help.

1) Is Monster the best bet, or could I do something cheaper and still get good performance? Amazon has Acoustic Research cable, 100ft, 16 gauge, for $22. Good deal, bad idea, or "I will never hear the difference"?

2) What gauge to use, or does it make any difference? They are Bose speakers if that matters, but not running them on a Bose system. They are probably 40-45 feet (total wire run distance) from the Receiver.

Thanks!!
