Elite Audio 20ft 2-Channel RCA Cable, Double-Shielded

Elite Audio Premium Series PRM20 is a 20-foot, double-shielded 2-channel RCA cable built with 99.9% oxygen-free copper and precision brass connectors to deliver low-noise, high-fidelity signal for car amplifiers, subwoofers, speakers, and processors.

Whether you're upgrading a car audio system or wiring a compact home stereo setup, the PRM20 was designed to carry left/right analog signals cleanly over distance. The combination of oxygen-free copper conductors, tinned copper shields, and a dedicated drain wire reduces electromagnetic interference and preserves audio detail, while flexible jacket materials and machined brass connectors help during installation and long-term use.

How does this cable reduce background noise and interference?

The PRM20 uses multiple layers of protection to keep unwanted noise out of the audio path. Double shielding—tinned copper braid plus an additional shield—and a copper drain lead provide a low-impedance return route that rejects radio frequency and electromagnetic noise common in vehicle environments.

• 99.9% oxygen-free copper conductors for minimal signal loss
• Dual tinned copper shields to block RFI/EMI
• Copper drain wire for improved grounding and noise rejection
• Machined brass RCA connectors for a solid, low-resistance contact

Will this cable work with my amplifier, subwoofer, or processor?

The PRM20 is a standard 2-channel RCA interconnect and is compatible with most consumer and car audio devices that use RCA inputs and outputs. Its universal connectors and robust build make it suitable for head units, aftermarket amplifiers, line-level processors, powered subwoofers, and many home AV components.

• Universal RCA terminations fit most audio gear
• 20-foot length provides flexibility for under-seat or trunk-mounted installations
• Designed for line-level signals; avoid using with high-level speaker outputs without proper adapters

How durable and reliable is the PRM20 for long-term installations?

Materials and construction target longevity in mobile and residential environments. Precision-machined brass connectors resist corrosion, and the tinned shielding improves resistance to oxidation; combined with a rugged, yet flexible jacket, the cable withstands routing, bending, and vibration.

• Corrosion-resistant brass connectors extend contact life
• Tinned shields prevent degradation in humid or harsh settings
• Flexible jacket simplifies routing through tight vehicle channels
• Solid conductor geometry maintains consistent signal transfer over time

What installation tips ensure the best performance?

Routing and grounding choices affect noise levels more than most users expect. Keep RCA runs away from power cables, secure connections firmly, and verify good chassis ground at the amplifier to maximize the PRM20's noise-reduction design.

• Route away from high-current wiring like alternator or battery cables
• Use twist or zip ties to maintain separation without pinching the cable
• Confirm solid ground at the amplifier or processor chassis
• Trim excess cable length rather than coil tightly to avoid inductive pickup

Who is this for: The Elite Audio PRM20 is aimed at audio enthusiasts, installers, and DIYers who need a dependable, long 2-channel RCA interconnect for car or compact home systems. If you prioritize low-noise signal transfer, corrosion-resistant connectors, and an easy-to-route, flexible cable for amplifiers, subwoofers, or processors, this cable offers a professional-grade option without specialty termination or custom fabrication.
