The Rockford Fosgate RFD4 distribution block is engineered to efficiently manage power distribution within your audio system. It provides a central hub for connecting your main power wire to multiple amplifiers or components, ensuring a clean and organized setup. Constructed from durable, custom-tooled solid brass, the RFD4 is built for longevity. Its HPP plating offers superior corrosion resistance, maintaining reliable connectivity even in demanding environments. The block features a single input terminal capable of accepting 1/0 AWG or 4 AWG wire, and three output terminals that support 4 AWG or 8 AWG wire. This flexibility is enhanced by removable interior adapter rings, allowing for easy adjustment to different wire gauges. The RFD4 is designed with a platinum finish, adding a premium aesthetic to your installation. It includes mounting holes with a 3/16" diameter, spaced 1 3/4" center-to-center, for secure attachment. The product is backed by a 1-year warranty from Rockford Fosgate, underscoring its quality and reliability. While sold as a single unit, it can be paired with additional RFD4 blocks for more complex power distribution needs.
