Description
Rockford Fosgate RFD4
The RFD4 is a 4 AWG distribution block from Rockford Fosgate, built to distribute power from a single large input to multiple outputs. It features a platinum‑finish custom modified solid brass body, with HPP (High Purity Platinum) plating for superior corrosion resistance. The block has removable adapter rings so you can adjust wire gauge sizes for both input and outputs. It supports either a 1/0 AWG or 4 AWG input, and up to three outputs (4 AWG or 8 AWG). It’s useful when you want to feed power (or ground) from one source into multiple amps or components in a clean, safe, and organised way.
