Yes unless playing very loud.
Any decent 12 gauge or larger copper stranded wire. Lower the number the bigger the wire. Not copper clad aluminum (CCA). Doesn't have to be expensive. Home Depot for local, monoprice, amazon, etc.
If you don't want to strip wire you can buy some speaker wire with banana plugs already installed and just plug into receiver and speakers. Pricier but easy.
