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.

Questions and Answers

Q1: What is the purpose of the RFD4 distribution block?

It splits one large power feed into three outputs, allowing you to run multiple amps or devices from one power input.

Q2: What wire sizes can I use with RFD4?
You can use 1/0 AWG or 4 AWG for the input, and 4 AWG or 8 AWG for the outputs. The adapter rings allow flexibility.
Q3: Does the RFD4 resist corrosion?
Yes, the HPP platinum finish helps protect it from corrosion and gives longevity.
Q4: Is installation difficult?
Not really — you need suitable wire gauges, strip them properly, and secure with set screws. Ensure it’s mounted securely. Manufacturer includes guidance.
Q5: How much power / current can it handle?
While the rating isn't explicitly “ohms-or watts based,” it supports large gauge wires like 1/0 AWG and 4 AWG, meaning it can handle high current suitable for multi-amplifier audio setups. Just ensure your wiring and other components are up to spec.
