I got most of my plates, wiring ect through Provo Wire in Vaughan(Ont). My buddy has an account there and gets excellent prices from them(they don't sell to the public), roughly half what many retail stores sell at. Canada computers has some decent prices on sub and hdmi cables.

You need In-wall rated wire...best to try an electrical supplier for it...for me that would be a place like Provo Wire or Hudco Electric Supply.

Half of communication is listening. You can't listen with your mouth.
