I dont compete in the car audio world and believe that the bigger the speaker wire running to the speakers, the more the current yout amps can put out to them. Think of a water hose as the wire and the water as the current. I am not saying that everyone should go and buy 12 gauge speaker wire. I am using the 16 gauge wiring that came with the speaker sets the I bought, MB Quarts. Just remember to run the speaker wires down the opposite side of that car, away from your power wires. Joe
