Please don't fall for the snake oil cables while we're at it Proper gauge copper wire will do it, terminations are your choice but bare wire ends are essentially the best. Avoid copper clad aluminum wire particularly if the ad isn't clear, an indicator is the price is too good to believe. You can usually go to your local home improvement store for sufficient speaker wire depending on in wall or not requirments.....or online places like monoprice.com for value or bluejeanscable.com for prettier stuff plus very good construction....
