I am helping someone set up a 7.1 system. the room was prewired for 5.1 and the only way to get the back two is by using flat wire. the carpet is being replaced so I figured that would be perfect. Here is what we got..

The run will be about 15 feet to a 8 ohm tower and I was wondering if there would be any benefit to doubling the wire if we have enough. (I don't mean bi-amping)
Does 2 16ga make a right? \:\)
