Power cables deliver the lifeblood of your system to your amps, so if you want premium system performance you need premium power cables. With so many low-quality cables on the market, DD wanted to offer their customers a product that could be counted on to deliver maximum current. Z-Wire is DD Audio’s no BS version of power cable. This means no fancy colors or trumped up technology. It’s just good ol’ red and black cable offered in a Tru-ID, AWG spec. The 8 gauge cable have a 5mm ID/ 6.5mm OD, 4 gauge cable have a 8mm ID/ 10mm OD, and the 0 gauge cables have a 12 mm ID/16mm OD. For maximum performance, we use a high strand count 100% oxygen free copper. This means you get 61% more current conductivity compared to CCA wires of the same size. Each strand is tinned to resist oxidation making it great for car and marine applications. We encased it all in a durable and yet highly flexible PVC jacket that is heat and oil resistant.
