Yes, get your speaker cable from Lowes, Home Depot or any other discout company. I would suggest #12, but #14 will probably do just as well.
Every once in a while you can get a good deal on "oxygen free" #12 wire on EBAY. You might check it out, but be careful, all is not what it is made out to be on EBAY.
