Hello, one last question...well, just for the heck of it. I am recieving a new Sony Sub(Sa-wm40) this week and recently bought an Ultralink 6m RCA type video interconnect cable from my local store which was having a sale and advised me not to buy a subwoofer only cable as they were mostly mockups of this cable sold at a higher price. My questions are as follows: 1) Despite the 'video' reference on the box, is this cable sufficient to connect from my receiver to my subwoofer? 2)Also, which way are the arrows on the cables supposed to point? extra: for my DVD player component cables, which way do those arrows point?
