Power cables are used to connect an external amplifier to the car battery and also to ground the amplifier. We mainly classify them according to their cross-section, but the price also depends on the composition of the conductor. We offer fully copper power cables for maximum conductivity as well as affordable CCA cables (copper with an admixture of aluminum), which are an ideal choice for common installations. OFC copper cables have better heat dissipation, lower specific resistance, more stable voltage or less susceptibility to oxidation compared to CCA cables made of a mixture of aluminum and copper. The highest quality OFC cables have tinned strands for corrosion protection and lower operating temperature. All cables are designed with an emphasis on durability, flexibility and long service life, and thanks to their high-quality insulation, they are also suitable for demanding conditions in the engine compartment of a vehicle. Variants in different colors are also available for easy distinction of plus and minus wires. The right power cable is key to the performance and safety of your entire sound system - choose the right one for your car today.
