Description
17-Foot Audiophile 4-Channel RCA with Silver-Plated Conductors, Triple Shielding and Locking Split-Tip Connectors
Product Overview
The Stinger SI8417 is a 17-foot (5.2 metres) 4-channel RCA interconnect from the Stinger 8000 Series. It uses oversized silver-plated copper conductors in a directional double twisted-pair construction with triple shielding braided copper outer shield, Mylar layer, and twisted-pair geometry to suppress interference across long cable runs. Pewter-finished precision machined locking split-tip connectors provide positive, rattle-free connection to RCA inputs and outputs, with channel identification markings and no solder joints in the signal path.
The 8000 Series incorporates Stinger's C3 Technology (Continuous Connection Construction), which refers to the elimination of in-line solder joints across the signal path from connector to connector. The cable uses a mono construction where each channel runs in a separate conductor path with its own shielding, ensuring channel independence over the full 17-foot run.
The 17-foot length suits extended runs in larger vehicles, utes, SUVs, and motorhomes where the amplifier is mounted in the rear of the vehicle and the head unit or signal processor is at the front.
Features & Benefits
-
Oversized silver-plated copper conductors — silver plating on the outer surface of the copper conductor reduces skin effect losses at high frequencies, contributing to full-spectrum signal transfer with tight transient response
-
Triple shielding construction — braided copper outer shield (broadband noise rejection), Mylar layer (RF and EMI rejection), and directional twisted-pair geometry (cancels magnetic induction) combine to suppress interference from alternator whine, ignition noise, and other automotive electrical sources
-
Directional construction — the cable is designed for unidirectional signal flow; install with the directional indicators oriented toward the destination component (amplifier or processor) for optimised performance
-
Locking split-tip connectors — the split-tip design grips the RCA socket with positive locking force to prevent vibration-induced intermittent contact; precision machined pewter-finished metal ends provide mechanical durability
-
Channel identification — connectors are marked to identify channel assignment across the 4-channel run, simplifying correct connection at both ends
-
C3 Technology (Continuous Connection Construction) — Stinger's designation for an in-line solder-free signal path from plug to plug; eliminates the micro-arcing and corrosion points that solder joints introduce over time
-
3 conductors per channel, 6 total — the third conductor per channel provides a dedicated ground return path per channel rather than shared ground, improving channel separation
-
Black mesh protective jacket — woven mesh outer jacket resists abrasion and flexing damage during routing through the vehicle
-
17-foot length — suited to long-run installations in utes, SUVs, vans, motorhomes, and boats where amplifiers are mounted in the rear

Frequently Asked Questions
What is C3 Continuous Connection Construction?
C3 is Stinger's designation for a construction method that eliminates in-line solder joints across the cable's signal path. In conventional cable construction, the conductor is soldered to the connector pin at each end — a joint that can develop micro-arcing, corrosion, and intermittent contact over time. C3 construction maintains a continuous conductor from pin to pin without relying on solder for electrical continuity, improving long-term signal integrity.
Why does triple shielding matter and what does each layer do?
Each shielding layer addresses a different type of interference. The outer braided copper shield provides broadband noise rejection, particularly for low-frequency sources like alternator whine. The Mylar layer beneath it rejects RF and EMI signals from mobile phones, ignition systems, and other high-frequency sources. The directional twisted-pair geometry of the signal conductors themselves uses differential cancellation — any magnetic field that induces noise into one conductor induces equal noise into the other; the pair's opposite polarities cancel the noise in the signal. Together, all three layers address the full spectrum of automotive electrical interference.
Is the cable directional and does it matter which way I install it?
Yes — the SI8417 uses directional construction. Install it with the directional indicators on the cable pointing toward the receiving component (typically the amplifier). Reversed installation may still function but is not optimised for the noise cancellation geometry built into the twisted-pair construction.
What do the locking split-tip connectors do differently from standard RCA plugs?
A standard RCA plug relies purely on friction between the plug barrel and the socket collar. A split-tip design adds a spring-loaded split at the centre pin, which expands to grip the interior of the socket's signal contact. This provides a positive mechanical lock that resists vibration-induced movement and maintains consistent contact force regardless of vehicle movement. The result is more reliable signal continuity in mobile audio installations where constant vibration is a factor.
The title says 5m but the specs say 5.2m — which is correct?
17 feet equals approximately 5.18 metres, which is correctly rounded to 5.2 metres in the specification sheet. The "5m" in the product title is a rounded approximation. The actual cable length is 17 feet / 5.2 metres.
