wire gauges have a limited amount of power they can safely handle. 12-14 gauge will be fine.

i can't recommend a specific model but look at the RMS power rating and get one around 100-125rms watts

Yeah. A wire's gauge tells you how thick the copper in the wire is. Lower gauge numbers means they're thicker so they can safely handle more current (and so handle more power).

Thanks for Gauge help :X And thanks for posting two sites I can purchase from, but any suggestions on the receiver itself?

stick to a well known brand in your price range that put out about 100-125 rms watts
