Stinger SI626 1.8m 6000 Series 2-Channel Shielded Directional Interconnects

Stinger SI626 6000 Series 2 Channel RCA Interconnect Cable 1.8 Metre with Triple-Twisted OFC Silver Cable and Locking Blue Connectors

The SI626 from Stinger is a 2 channel RCA interconnect cable from the 6000 Series range, measuring 1.8 metres (6ft) in length. Built with triple-twisted OFC and silver cable, precision-machined locking blue anodised connectors, Mylar shielding, and C3 Technology, it delivers premium audiophile-grade signal transfer with superior noise rejection across both channels. A lifetime warranty against manufacturer defects is included.

Product overview

The Stinger 6000 Series sits above the 4000 Series in the Stinger RCA range, designed for installations where maximum signal integrity and noise rejection are the priority. The triple-twisted OFC and silver cable construction provides exceptional current transfer with virtually no voltage loss, while the Mylar shielding adds a further layer of protection against alternator noise and electromagnetic interference that can affect signal quality in demanding installation environments.

The precision-machined locking connectors are finished in blue anodised metal, providing a secure, rattle-free connection at each RCA socket and a premium appearance suited to high-end installations. At 1.8 metres, the SI626 is suited to compact installations where the amplifier is located close to the head unit or signal source. Colour-coded channel identification inside the RCA barrel simplifies correct channel connection, and moulded strain reliefs at each connector protect the cable against fatigue from repeated handling.

Features and benefits

Triple-twisted OFC and silver cable construction: The triple-twisted conductor design using OFC and silver cable delivers exceptional signal transfer, minimal voltage loss, and outstanding noise rejection, setting the 6000 Series apart from standard OFC-only RCA cables.

Mylar shielding for superior noise rejection: The Mylar shielding layer provides increased protection against alternator noise and electromagnetic interference, maintaining clean signal transfer in demanding installation environments where noise is a concern.

Precision-machined locking blue anodised connectors: The machined metal connectors lock securely into each RCA socket, preventing disconnection from vibration, and the blue anodised finish provides a premium appearance suited to high-end custom installations.

C3 Technology (Continuous Connection Construction): Maintains a continuous, consistent conductor path throughout the cable length, providing unmatched signal transfer and improved frequency response across both channels.

Directional twisted-pair construction: The directional twisted-pair winding pattern protects against electromagnetic interference and broadens dynamic range, maintaining clear channel separation across the full cable run.

Colour-coded channel identification inside RCA barrel: Channel identification colour coding is located inside the RCA barrel for a clean external appearance while still allowing correct channel connection during installation.

Lifetime warranty against manufacturer defects: The SI626 is covered by Stinger's lifetime performance warranty against manufacturer defects.

Frequently asked questions

What is the difference between the SI626, SI6212, and SI6217?
All three are 6000 Series 2 channel RCA interconnects with identical construction and specification. The SI626 is 1.8 metres (6ft), the SI6212 is 3.7 metres (12ft), and the SI6217 is 5 metres (17ft). Select the length that suits the cable run distance in your specific installation.

What is the difference between the 6000 Series and the 4000 Series RCA cables?
The 6000 Series uses triple-twisted OFC and silver cable construction and adds Mylar shielding and precision-machined locking blue anodised connectors, placing it above the 4000 Series for noise rejection, signal integrity, and build quality. Both include C3 Technology and a lifetime warranty. For demanding installations where alternator noise or signal integrity is a concern, the 6000 Series is the more appropriate choice.

What does the locking connector design do?
The precision-machined locking connectors secure firmly into each RCA socket, preventing the plug from working loose due to vibration during vehicle operation. This maintains consistent signal transfer and eliminates the intermittent connection issues that can occur with standard non-locking RCA plugs in high-vibration environments.

Does the SI626 include a warranty?
Yes. The SI626 is covered by Stinger's lifetime performance warranty against manufacturer defects. Contact us for further details on warranty claims and conditions.

Is the SI626 available in other channel counts or lengths?
The Stinger 6000 Series RCA range includes cables in various channel counts and lengths. Contact us to confirm the full range of available options to suit your specific installation requirements.
