Our Audiobank Copper Aluminum series cable was designed specifically to be larger than the competition. Copper Clad Aluminum is less conductive than Oxygen Free Copper when comparing like sized conductors. CCA however is also much less expensive. So by increasing the area in our cable, Audiobank was able to achieve similar performance to OFC, but without the higher cost. For this exact reason is why our cable is larger, to achieve similar performance, for less money. The graph below shows, based on area, our cable is at least 40% larger than comparable brands. The New 0 Gauge AudioBank Amp Kit has a little bit of everything and provides great power and durability for all of your car audio installation needs! The package includes bendable cables that allow you to maneuver through tight spots, a turn on wire, several terminals, and much, much more. If youre looking for a quality buy at a great price, this is it!
