Nine individually jacketed EIA colour-coded 18GA conductors in a single flexible outer jacket hyper-twist construction, 41-strand count, perfect for 4-channel amplifier installations, head unit wiring, and automotive electronics.
The Stinger SGW991 is a 30-metre roll of 9-conductor speed wire, combining nine individually jacketed 18GA wires in a single highly flexible outer jacket. The hyper-twist construction delivers excellent flexibility for routing through tight spaces, while EIA-standard colour coding matches the wiring colours found on aftermarket head units and audio devices reducing installation time and wiring errors.
The 9-conductor format is ideal for 4-channel amplifier speaker installations plus a remote turn-on wire, ECU wiring, engine sensor harnesses, and other multi-wire automotive electronics applications.

What is speed wire and why is it useful?
Speed wire combines multiple individually jacketed conductors inside a single outer jacket, allowing installers to route all wires for a given run (e.g., all four speaker channels plus remote turn-on) through the vehicle in a single cable pass. EIA colour coding makes termination fast and error-free, significantly cutting installation time.
What does 9-conductor suit in a car audio installation?
A 4-channel amplifier requires eight speaker connections (four channels × two wires per channel) plus a remote turn-on wire — totalling nine conductors. The SGW991's 9-conductor format is matched exactly to this common installation requirement.
Is 18GA suitable for speaker wiring?
Yes, for speaker signal wiring in standard car audio installations — connecting a head unit's amplified outputs or a 4-channel amplifier to door or rear speakers at typical lengths. For high-power amplifier to speaker runs, 16GA or 12GA wire (SPW516BK or SPW512BK) is recommended.
Is the SGW991 suitable for non-audio automotive wiring?
Yes. The EIA colour coding and multi-conductor format are well-suited to ECU wiring, engine sensor harnesses, lighting control wiring, and any application requiring multiple small-gauge conductors routed together.
Is 30m sufficient for most installations?
30m provides enough 9-conductor speed wire for approximately four to six standard 4-channel amplifier installations (typically 5–7m per vehicle), making it a good workshop stock roll.
