Stinger XI3217 X3 Series 2-Channel RCA Interconnect 17ft

Stinger XI3217 X3 Series 2-Channel RCA Interconnect 17ft

At the top of the Stinger RCA range, the XI3217 combines silver-plated OFC conductors, locking RCA ends, dual-layer EMI shielding, and directional noise-cancelling construction in a 17-foot 2-channel interconnect built for uncompromising signal integrity.

Product Overview

The XI3217 is Stinger's flagship X3 Series 2-channel RCA interconnect cable, engineered for car audio installations where signal quality between the source unit and the amplifier is the priority. At 17 feet in length, it covers the full run from a head unit to a boot-mounted amplifier in most vehicles with cable to spare. Every element of the X3 design targets a specific source of signal degradation: the C3 Tech construction method optimises continuous conductor contact, the Lock Tip RCA connectors eliminate the signal-robbing looseness of standard push-fit RCAs, the I.D. dual-layer shielding suppresses both radiated and conducted noise, and the directional twisted-pair architecture creates a noise-cancelling architecture within each channel. Silver-plated pure OFC copper conductors and Body Armor nylon-woven outer protection complete a cable built to the standard that the rest of a high-performance car audio system demands.

Features & Benefits

C3 Tech (Continuous Connection Construction): Stinger's proprietary C3 construction method provides unmatched signal transfer by ensuring continuous, uninterrupted conductor contact throughout the full cable length, eliminating the micro-discontinuities that can introduce noise and signal loss in conventionally constructed cables.

Lock Tip Locking RCA Connectors: The Lock Tip connector uses a rotational locking end combined with a Quad-Clamp precision 4-cut RCA contact, delivering the highest possible locking and clamping force at the connection point. This eliminates the intermittent contact and signal degradation caused by loose RCA connections under vibration, which is the most common cause of noise in car audio signal chains.

I.D. Interference Defense Dual-Layer Shielding: Two independent shielding layers work in combination to suppress noise from two different sources. An inner Mylar foil layer rejects EMI from radiated electromagnetic sources such as alternators, ignition systems, and mobile devices. An outer copper mesh layer absorbs conducted radiated noise from within the cable itself. Together, they provide a level of noise rejection not achievable with a single-layer shield.

Dynamic Signal Flow with Silver-Plated OFC Conductors: The conductor is constructed from finely stranded pure OFC (Oxygen-Free Copper) with a silver plating applied to each strand. OFC minimises resistance and eliminates the oxygen-related oxidation that degrades signal quality over time, while the silver plating optimises the conductor's performance across the full audio frequency spectrum for a dynamic, detailed listening experience.

Noise Shield Directional Construction: Three tightly twisted conductor bundles per channel (positive, negative, and signal drain) are arranged in a directional architecture that uses the physics of twisted-pair noise cancellation to reject interference. The directional construction means the cable is designed to be installed in a specific orientation for maximum noise rejection.

Body Armor Protection: The outer jacket uses high-strength nylon fibres woven tightly around the ultra-flexible PVC inner cable, providing mechanical protection against sharp metal edges, vibration fatigue, and moisture ingress during installation and throughout the life of the cable.

Double Twisted-Pair Construction: Each channel uses a double twisted-pair conductor arrangement that enhances noise rejection beyond what a single twisted pair provides, working in conjunction with the directional architecture and dual-layer shielding for maximum signal cleanliness.

Technical Specs

Goes Well With

The XI3217 is best suited to high-performance amplifier installations where the signal quality between the head unit and the amplifier is critical to the overall system performance. It is well matched to premium amplifiers across the Rockford Fosgate, Hertz, Morel, and AudioControl ranges, where the amplifier's low noise floor and high dynamic range can only be realised with an RCA cable that does not introduce noise or signal loss into the chain. The 17-foot length suits most full-length vehicle runs from a dash-mounted head unit to a boot-mounted amplifier, with the locking RCA ends providing secure, rattle-free connections at both ends of the run.

Frequently Asked Questions

What is the benefit of silver-plated conductors over standard OFC copper?

Standard OFC copper provides low resistance and excellent signal transfer. Silver plating each individual strand of the OFC conductor further reduces the effective resistance at the surface of each strand, where the majority of high-frequency audio signal travels due to the skin effect. This optimises the cable's performance across the full 20Hz-20kHz audio frequency range, particularly at higher frequencies where signal vs. frequency interaction matters most to audio quality.

What does the directional construction mean, and how do I install it correctly?

The directional construction means the cable's internal twisted-pair architecture is orientated to cancel noise most effectively when signal flows in one specific direction. Arrows or directional markings on the cable indicate which end should connect to the source unit (head unit) and which end should connect to the amplifier. Installing the cable in reverse does not damage it but reduces the effectiveness of the noise-cancelling architecture.

How do the Lock Tip locking RCA connectors differ from standard RCA connectors?

A standard push-fit RCA connector relies on friction between the plug body and the socket to maintain contact, which can loosen under vibration and cause intermittent noise or signal dropout. The Lock Tip connector adds a rotational locking mechanism and a Quad-Clamp precision 4-cut contact that physically clamps and locks onto the RCA socket, maintaining consistent contact force regardless of vibration, temperature cycling, or mechanical stress.

What does dual-layer shielding provide that a single shield does not?

A single shielding layer typically addresses either radiated electromagnetic interference from external sources or conducted noise from within the cable, but not both equally well. The XI3217 uses a Mylar foil inner layer specifically tuned for rejecting external EMI from alternators, ignition systems, and radio frequency sources, and a copper mesh outer layer specifically designed to absorb conducted radiated noise generated within the cable's own conductors. The combination of both layers provides substantially better total noise rejection than either layer alone.

Is 17 feet sufficient for most vehicle installations?

At 17 feet (approximately 5.2 metres), the XI3217 covers the full run from a dash-mounted head unit to a boot-mounted amplifier in most passenger cars, SUVs, and medium-sized vans with cable to spare for routing around obstacles. For larger vehicles or installations where the cable must be routed significantly away from the direct path, measure the intended routing distance before purchase.
