Description
8000 Series 2-Channel RCA Cable 3ft, Oversized Silver-Plated Copper, Triple Shielding, Locking Metal Ends, C3 Tech, No Solder Joints.
Product Overview
The Stinger SI823 is a 3-foot (approximately 0.9-metre) 2-channel RCA interconnect from the 8000 Series the shortest length in the 8000 Series range, suited to compact installations where the amplifier is in very close proximity to the head unit, such as under-seat builds, behind-dash amplifier installations, or component-to-component connections within the same location.
The SI823 delivers the full 8000 Series specification at the shortest available length: oversized silver-plated copper conductors, three conductors per channel (positive, negative, signal drain), triple shielding (Dual Mylar plus braided), directional high-rate double twisted-pair construction, C3 Tech (Continuous Connection Construction) with no solder joints throughout, precision machined pewter-finish locking metal ends with channel identification, moulded strain reliefs, and a black mesh protective jacket.

Features & Benefits
-
Oversized Silver-Plated Copper Conductors Silver-plated copper combines the high-frequency precision of silver with the current-carrying capacity of copper — delivering tight bass response and crystal-clear high-frequency detail across the full audio spectrum. The oversized gauge reduces conductor resistance across the 3-foot run.
-
Triple Shielding — Dual Mylar + Braided Three shielding layers — dual Mylar foil layers combined with braided shielding — provide multi-directional protection against alternator whine, ignition noise, and electromagnetic interference from surrounding vehicle wiring. Particularly relevant in complex under-dash and under-seat installations where RCA cables run near power cables.
-
Three Conductors per Channel Dedicated positive, negative, and signal drain conductors per channel isolate the shield drain from the audio signal return — reducing the noise interaction present in standard two-conductor RCA designs.
-
C3 Tech — No Solder Joints Stinger's C3 (Continuous Connection Construction) eliminates all solder joints throughout the cable — removing the resistance discontinuities and potential failure points associated with solder-based connections in the vibration-heavy automotive environment.
-
Precision Machined Locking Metal Ends with Channel ID Pewter-finished precision machined connectors lock securely to RCA inputs and outputs, preventing vibration-induced disconnection. Channel identification markings distinguish left and right channels at both ends.
-
Directional High-Rate Double Twisted-Pair Construction Directional twisted-pair winding pattern maximises noise cancellation when signal flows from source unit to amplifier. Directional markings indicate correct installation orientation.
-
Moulded Strain Reliefs + Black Mesh Jacket Strain reliefs protect the cable-to-connector junction from flex fatigue. The black mesh outer jacket provides physical protection and a clean, professional finish in the completed installation.

Length selection guide: SI823 (3ft / 0.9m) — very close proximity. SI824 (4ft / 1.2m) — close proximity. SI826 (6ft / 1.8m) — short run. SI8212 (12ft / 3.7m) — standard boot-mount. SI8217 (17ft / 5m) — large vehicles.
Frequently Asked Questions
What makes the 8000 Series different from standard RCA cables?
The 8000 Series combines oversized silver-plated copper conductors, C3 Tech solder-joint-free construction, triple shielding (Dual Mylar plus braided), and precision machined locking metal ends — features not found in standard RCA cables. Together they deliver audiophile-grade signal quality and long-term reliability suited to high-performance car audio systems.
What is C3 Tech and why does it matter?
C3 Tech (Continuous Connection Construction) eliminates all solder joints within the cable assembly. Solder joints introduce resistance and potential failure points — particularly under automotive vibration. Removing them ensures maximum signal transfer and channel separation throughout the cable's service life.
Is the SI823 a directional cable?
Yes — the SI823 features directional high-rate double twisted-pair construction. Install with the directional markings on the cable running from the head unit toward the amplifier for maximum noise cancellation.
What does the triple shielding protect against?
Triple shielding — Dual Mylar foil layers combined with braided shielding — provides three layers of protection against alternator whine, ignition noise, and electromagnetic interference. This is particularly relevant in under-dash and under-seat installations where RCA cables run in close proximity to power cables and vehicle wiring.
Can the SI823 connect a head unit to a 4-channel amplifier?
The SI823 is a 2-channel cable — it connects one stereo pair of RCA outputs (front or rear) to the corresponding inputs on a 4-channel amplifier. For a full front and rear connection, two SI823 cables are required. A dedicated 4-channel RCA cable is the single-cable alternative.
