Just a clarification to leoinstereo ... if you make it a 30 amp circuit (a good idea) it must be a minimum of 10 gauge wire ... 20 amp would be a minimum of 12 gauge ... 15 amp a minimum of 14 gauge. You can always put more wire however ,,, in my system I have 20 amp circuits for my main amps but used 10 gauge wire. Good Listening!!
