Description of RWK41:
ThThe Rockville RWK41 4 AWG (American Wire Gauge) amp kit has the following differences over other amp kits on the market at this price point.. . . Our RCA cables are 100 % copper. These are top of the line RCA cables. . . Better Resistance: The only thing that really matters with wires is the resistance rating. This is a measurement of conductivity and how much signal is loss per foot of wire. Since Rockville wires are made with around 3 times as much copper as any other wire at this price point, these wires had a much better resistance rating which means they will transfer more power to your amps than the other brands.
