Rockford Fosgate RFI-20 20-Foot Twisted Pair RCA Cable

The Rockford Fosgate RFI-20 is a 20-foot RCA signal interconnect designed for routing low-level audio between compatible car-audio components. It provides a practical connection length for installations where an amplifier, processor, or equalizer is mounted away from the source unit. Its stereo RCA construction is suited to systems requiring a left and right signal path.

This cable is intended for installers and vehicle owners building or upgrading an RCA-equipped car-audio system. The twisted-pair design is made to help reject noise that can enter signal wiring in an automotive environment. That makes it a useful choice when signal cables need to travel through a vehicle alongside other wiring.

OFC, or oxygen-free copper, conductors support dependable signal transfer and corrosion resistance. The RFI-20 also uses platinum-plated RCA ends for additional corrosion resistance at the connection points. These details focus on maintaining a clean, secure signal path between compatible components.

A split center pin is used at each RCA connector to promote a secure connection. The cable features double shielding and a frosted outer shield designed for durability and flexibility. Together, these construction elements help the cable remain manageable during routing while supporting noise-rejection performance.

Use the RFI-20 to connect RCA preouts from a compatible head unit or signal processor to an amplifier, or to link other compatible line-level audio components. Its 20-foot length is appropriate for many full-vehicle runs, including installations with amplifiers mounted in the trunk or cargo area. Confirm the number of RCA channels required by the system before purchase, as this is a two-channel stereo interconnect.

Key Features

• 20-Foot Length: Provides reach for many front-to-rear vehicle installations.
• Twisted-Pair Construction: Helps reject unwanted noise in signal wiring.
• OFC Conductors: Oxygen-free copper supports corrosion-resistant signal transfer.
• Double Shielding: Adds protection against RFI and EMI noise.
• Split Center Pins: Promotes a secure fit at RCA connections.
• Platinum-Plated Ends: Help resist corrosion at the connectors.

Design & Installation

The RFI-20 uses a twisted-pair RCA design with OFC conductors, double shielding, platinum-plated connector ends, and split center pins. Its frosted outer shield is designed to provide durability and flexibility during cable routing. The cable is supplied as one stereo, two-channel RCA interconnect.

Route the cable between compatible male RCA connections, such as a source unit, processor, equalizer, or amplifier. Plan the 20-foot run before installation and avoid sharply bending, pinching, or damaging the cable during routing. For systems needing more than two RCA channels, use additional compatible interconnects as required.
