Stinger SGW9920 Pre-Cut Speedwire 9 Core Cable - 6 Metres

Stinger SGW9920 18GA 9-Conductor Speed Wire, 6m Pre-Cut Single Pack

Nine individually jacketed EIA colour-coded 18GA conductors in a single flexible outer jacket hyper-twist construction, pre-cut to 6 metres for a single 4-channel amplifier installation.

Product Overview

The Stinger SGW9920 is a pre-cut, single-pack 6-metre length of 9-conductor speed wire the retail single-installation version of the SGW991 bulk roll. It contains nine individually jacketed 18GA conductors with EIA-standard colour coding in a single hyper-twist flexible outer jacket, combining all wiring needed for a 4-channel amplifier speaker installation plus remote turn-on wire into a single cable run.

The 6-metre pre-cut length suits most standard vehicle amplifier installations.

Frequently Asked Questions

What is the difference between the SGW9920 and the SGW991?

Both are 18GA 9-conductor EIA speed wire with the same construction. The SGW9920 is a pre-cut 6m single pack — suited to a single installation. The SGW991 is a 30m bulk roll — suited to workshop or multi-vehicle installer stock. Choose based on how many installations you're doing.

Is 6m sufficient for most 4-channel amplifier installations?

6 metres suits most standard installations where the amplifier is mounted in the boot and the head unit is in the dash — a typical distance of 4–6m. For longer runs or larger vehicles, consider the SGW991 bulk roll to cut a custom length.

What does the 9-conductor format provide for a 4-channel amplifier?

A 4-channel amplifier requires eight speaker connections (four channels × two wires per channel) plus a remote turn-on wire — exactly nine conductors. The SGW9920 is purpose-built for this common installation requirement.

Is 18GA suitable for speaker wiring?

Yes, for standard car audio speaker connections from a head unit or 4-channel amplifier at typical installation lengths. For high-power amplifier-to-speaker runs, 16GA or 12GA wire is recommended.

Is this wire suitable for non-audio automotive wiring?

Yes. The 9-conductor EIA colour-coded format is also well-suited to ECU wiring, engine sensor harnesses, and other multi-wire automotive electronics applications.
