Bought 150" of Monster cable on Ebay. I didn't realize that the cable was a 4 conductor type. How would one install either front speakers or rear speakers when they will be on opposite sides of a room about 14' apart. The other end is easy because the Left and Right terminals of my A/V receiver are close together. They must make this stuff to make installation easier but I can't figure it out unless you remove the outer insulation and run the wires with only the inside insulation---that doesn't seem to make sense to me.
