Description
Stinger SI8217 8000 Series 2 Channel Triple Shielded RCA 17ft
The Stinger SI8217 is a 2 channel, 17ft (5m) audiophile-grade RCA interconnect from the 8000 Series, built for longer head unit to amplifier runs in demanding car audio installations. Silver-plated copper conductors, triple braided shielding, and Continuous Connection Construction (C3 Tech) maintain signal purity across the full cable length.
Product overview
At 17ft (5m), the SI8217 suits boot-mounted amplifier installations and any vehicle where the amplifier sits well back from the head unit. The longer run places greater demands on shielding and conductor quality, and the 8000 Series construction is built specifically to meet those demands.
Silver-plated copper conductors extend frequency response beyond what plain copper achieves. Oversized conductor sizing contributes to tight bass response and clear high-frequency detail across the full 17ft run. Three conductors per channel, six in total across the stereo pair, support the 2 channel signal path throughout.
Shielding uses three independent layers: triple braided construction, Mylar wrapping, and directional high-rate double twisted-pair geometry. The longer the cable run, the more opportunity there is for interference to enter the signal path, and the SI8217's layered approach addresses that directly. Twisted-pair winding maintains consistent signal timing, keeping both channels phase-accurate through active crossovers or DSP systems.
Precision machined locking metal ends grip RCA sockets securely and carry channel identification markings to keep left and right correctly assigned across a longer installation. No solder joints appear in the signal path, maintaining true channel separation over the full 17ft. The black mesh outer jacket handles the wear of a longer routing run and reduces friction when pulling the cable through door trims or under carpet.
Features and benefits
Silver-plated copper conductors. The combination of copper and silver extends frequency response, delivering tight bass and crystal-clear highs without the colouration that lesser conductor materials introduce.
17ft (5m) cable length. Suits boot-mounted amplifiers and longer head unit to amplifier runs without the need for cable joins or extensions.
C3 Tech (Continuous Connection Construction). Stinger's proprietary construction method eliminates breaks in the signal path, providing consistent signal transfer across the full 17ft cable length.
Triple braided shielding with Mylar layer. Three layers of braided shielding plus a Mylar wrap deliver strong noise rejection across the full cable run, critical where longer routing paths pass near power wiring and interference sources.
Locking split-tip connectors. Precision machined metal ends lock onto RCA sockets to prevent accidental disconnection and maintain a solid signal contact point.
No solder joints. Solder-free construction maintains true channel separation and removes a common point of connection failure across both channels.
Directional double twisted-pair winding. High-rate directional winding patterns protect against interference and ensure consistent signal timing across the stereo pair.
Molded strain reliefs. Reinforced connector entry points protect the cable from flex fatigue at the point of greatest mechanical stress.
Channel identification markings. Clearly marked connectors make it straightforward to keep left and right channels correctly assigned across a longer installation.
Black mesh protective jacket. The braided outer jacket withstands the handling demands of a longer installation run and reduces friction when routing through tight spaces.
Pewter finished ends. Suits high-end build aesthetics while providing a durable, corrosion-resistant surface on the connector body.

Frequently asked questions
What channel configuration does the SI8217 support?
The SI8217 carries two channels, covering a stereo left and right signal pair. It suits 2 channel amplifiers, monoblock amplifiers fed via a Y-splitter, or any installation requiring a single stereo RCA run at longer length.
Is 17ft sufficient for a boot-mounted amplifier installation?
At 5m (17ft), the SI8217 covers the majority of passenger vehicle installations from a dash-mounted head unit to a boot-mounted amplifier. If you are unsure whether the length suits your specific vehicle, contact us before purchasing.
How does the SI8217 differ from the SI826?
Both are 2 channel 8000 Series RCA cables sharing identical construction and shielding specifications. The SI8217 is 17ft (5m) and suits longer amplifier runs, while the SI826 is 6ft and better suited to under-seat or close-mounted amplifier positions.
Does longer cable length increase the risk of noise pickup?
It can, which is why the SI8217's triple braided shielding and Mylar layer are particularly important at 17ft. The layered shielding, combined with directional double twisted-pair construction, protects the signal across the full run even when routed near power cables or other interference sources.
Does the SI8217 work with any RCA-equipped head unit or amplifier?
Yes. The SI8217 uses standard RCA connectors and is compatible with any head unit or amplifier fitted with RCA inputs and outputs. The locking split-tip connectors seat securely in standard RCA sockets across all major brands.
