I have a Yamaha YHTS400 and am looking for longer speaker wire. The length they gave me is only 3m and is too short. I want to buy longer wire but I cannot seem to find 6 conductor speaker wire anywhere online. The reason its 6 conductor is because it is connecting 3 speakers in the sound bar. I want to sit the sound bar on my mantle and run the wire through the wall. Does anyone know where I can find 6 conductor or can I use something else i.e. 6 conductor regular stranded wire?
