Rockville's exclusive Professional Marine Installation Kit features top of the line accessories which have been specifically engineered to withstand the toughest of marine environments. You will hear the difference and we guarantee you will not be disappointed! 

Rockville Marine Audio Interconnect cables are specifically engineered to withstand the challenges of both salt water and fresh water marine installations. The utilization of tinned Oxygen Free 100% copper conductors with polyethylene dielectrics in a twisted-pair arrangement optimizes noise rejection. The small-diameter white PVC jacket is ultra-flexible enabling our cables to be easily routed around bends and through tight spaces. Our exclusive molded connector features a water proof inner cap that is heat shrunk in place over all solder connections thus guaranteeing a completely water proof and corrosion resistant connection. The locking plug design with split pin technology further insures tight connections that will not vibrate free even during the most extreme boating maneuvers.

Our Marine Grade Speaker Cables are engineered for maximum signal transfer with minimum impedance loss. The cable strands are all individually tinned, fine-strand, oxygen-free copper with aluminum composite construction and provide a high-fidelity speaker connection that is especially engineered for the marine environment. Woven down to a flat shape, the cables can be easily routed throughout the bulkhead with ease. 

Rockville Marine Power Cables feature strands which are all individually tinned, fine-strand, oxygen-free copper with aluminum composite construction corrosion resistant and marine-ready. Fine-strand construction and soft PVC jacket deliver excellent flexibility. Our marine cables are much better quality than standard CCA wire kits. These kits have a very generous amount of copper in them. They are very similar in quality to the best brands kits on the market. The thickness of the wire is true-gauge. We have seen other brands who use thick plastic but very little copper inside the wire. Rockville wires are honest, true-to-spec and will make your music sound great.
