Rockford Fosgate RFTB4 4 AWG Barrier Spade Terminals

The Rockford Fosgate RFTB4 is a four-pack of 4 AWG barrier spade terminals for power and ground wiring in automotive audio installations. Its fork-shaped terminal end is designed for connections that use a barrier strip or screw-terminal connection point. These terminals provide a clean termination option when building or servicing a 4 AWG wiring run.

This accessory is intended for installers and vehicle owners working with compatible 4 AWG cable. The seamed crimp-style barrel allows the terminal to be crimped onto the stripped end of the wire. It is a practical choice for organizing wiring at distribution blocks, amplifiers, and other compatible connection points.

The RFTB4 does not alter the sound of an audio system; its role is to create a secure, serviceable electrical connection. Properly matched terminals help keep power and ground wiring orderly while making connected equipment easier to remove or inspect. The fork profile can be positioned around an appropriate screw terminal without fully removing the screw.

Rockford Fosgate specifies an HPP-plated, platinum-finish design for corrosion resistance. The package also includes red and black protective boots for positive and negative identification. This helps distinguish power and ground connections during installation and future service.

Use the RFTB4 as part of a complete 4 AWG wiring plan with cable, protection devices, distribution hardware, and equipment terminals selected for the application. Confirm that both the cable gauge and the mating barrier terminal are compatible before installation. A proper crimping tool and careful cable preparation are important for a dependable result.

Key Features

• 4 AWG Compatibility: Designed for compatible 4 AWG power or ground cable.
• Barrier Spade Profile: Fork end suits compatible barrier-strip and screw-terminal connections.
• Seamed Crimp Style: Provides a crimp-on termination method for stripped cable.
• HPP Plating: Adds corrosion-resistant plating to the terminal surface.
• Polarity Identification Boots: Red and black boots help identify positive and negative wiring.
• Four-Pack: Includes four barrier spade terminals for multi-connection projects.

Design & Installation

The RFTB4 uses a seamed crimp-style design with a platinum finish and HPP plating. Its fork-shaped spade end is made for barrier-style connection points, while the included red and black protective boots support clear polarity identification. The package contains four terminals.

Match these terminals only with compatible 4 AWG cable and a compatible barrier or screw-terminal connection point. Strip the cable to suit the crimp barrel, crimp with an appropriate tool, and fit the polarity boot as needed before making the final connection. Inspect the crimp and verify polarity before energizing the audio system.
