Rockford Fosgate RFDB1 Battery Terminal

The Rockford Fosgate RFDB1 is a platinum-plated car audio battery terminal built from custom-tooled solid brass. It accepts both positive and negative connections using the supplied sizing ring and provides multiple wire-size inputs for flexible installation.

Installers needing 1/0 or 4 AWG and 8 AWG inputs

This terminal suits installers who need to run 1/0 or 4 AWG power leads alongside 8 AWG wires from a single battery post. It is not for systems that require only a single small-gauge connection or for buyers who want a terminal without platinum plating.

Brass construction with supplied sizing ring

Installation uses the included sizing ring to match the battery post polarity. The solid brass body and HPP plating resist corrosion, but overtightening the set screws can strip the brass threads.
