Eliminated Unwanted Noises and Maximizes Signal Transfer. Engineered to withstand daily harsh marine conditions. Protected against corrosion and its soft, flexible PVC jacket surrounds. Tinned wire has superior corrosion resistance.
UL1426 Premium Oxygen Free Copper Boat Cable. Resistant to extreme cold, salt water, battery acid, oil, gasoline and ultra-violet radiation. Exclusive insulation is rated at 600 volts, 105° C dry and 75° C wet, and is resistant to heat and abrasion. Drawn copper, unidirectional lay for ultimate in sound quality. Exceeds all UL 1426, US Coast Guard Charterboat (CFR Title 46) and ABYC standards.
Using a propriety blend of pure copper wiring and special winding technique, we were able to reduce the "impedance skin effect" reducing noise while maintaining sound purity with minimal to zero impedance gain. Installation in the tightest of corners are easily conquered, thanks to our Super-Flex insulation. Rockville marine speakers cables are durable, very flexible and easy to use. The Super-Flex jacket was designed to handle the most extreme conditions. These wires meet the high-powered demands of amplifiers and speakers.Designed for purity and longevity. Black insulating jacket visually blends smoothly in to marine audio environment. About Rockville Quality Control Procedures.
