Metra Electronics R3R4-100

In custom car audio installations, transmitting crystal-clear, uncolored audio signals from the head unit to your amplifiers requires high-fidelity interconnect cabling. Manufactured by Metra Electronics—the gold standard in 12-volt installation accessories—the High-Performance RCA Audio Interconnect Cable (Part No. R3R4-100) is engineered specifically to provide superior signal transfer while rejecting electromagnetic interference (EMI) and alternator whine.

Shielded Twisted-Pair Construction and Connector Architecture

The R3R4-100 is meticulously constructed using professional-grade materials designed for rugged automotive environments:

• Low-Loss Twisted-Pair Geometry: Internal signal conductors are tightly twisted together to actively cancel out induced electrical noise and radiated interference from vehicle computers and power wiring.

• Precision-Molded RCA Ends: Equipped with split-tip, corrosion-resistant nickel- or gold-plated metal ends that maintain a tight, secure friction fit on both head-unit outputs and amplifier inputs.

• Flexible Protective Jacket: Encased in a durable, ultra-pliable outer sleeve that resists kinking, abrasion, and tight-radius stress when routed behind dash panels and door sills.

Key Features and Functional Capabilities

Deploying Metra R3R4 RCA interconnects in your mobile audio system delivers major operational advantages:

1. Noise-Free Signal Clarity

The multi-layer shielding architecture blocks stray electrical noise, ensuring your music plays back with pristine clarity, zero static, and a silent background floor.

2. Generous Length and Versatility

Optimized length formatting makes it ideal for running signal cleanly from front-dash source units to trunk- or under-seat-mounted multi-channel amplifiers.

3. Professional Installer Durability

Designed to withstand the rigors of professional shop installations, holding up under aggressive pulling through tight vehicle chassis channels.
