Is this as simple as twisting two wires together and plugging it into one slot? I will have 4-16 running through the house for ambient music in the bedrooms (small 30-50W speakers or so), but from what I'm reading 16ga isn't good enough for the home theater. If it is this simple, what's the guage equivelant of two 16s?

If it helps, I'm consider the M3Ti's+VP150 for the front.
