Stinger SPW18TR 8 Gauge Red OFC Hyper-Twist Power Cable 76 Metre Roll The SPW18TR from Stinger is an 8 gauge red OFC power cable supplied in a 76 metre roll. Built with high strand count true-spec oxygen-free copper conductors in a hyper-twist construction under a translucent red matte PVC jacket, it delivers minimal resistance, excellent flexibility, and durability suited to the extremes of the automotive environment. Product overview Power cable quality has a direct impact on how much current reaches the amplifier and how the system performs under load. The SPW18TR uses true-spec 100% oxygen-free copper in a high strand count hyper-twist construction, combining low resistance with the flexibility needed to route cable cleanly through a vehicle without kinking or fatigue. The matte translucent red PVC jacket is oil resistant and rated for extreme temperature exposure, providing durable insulation suited to underbonnet and cabin routing in automotive installations. The red colour follows standard automotive wiring convention for positive power runs, making the SPW18TR the natural choice for the main power cable in an 8 gauge amplifier installation. The 76 metre roll is well suited to trade and installer use across multiple vehicle installations and can be cut to the required length for each application. Features and benefits 8 gauge high strand count OFC conductors: True-spec 100% oxygen-free copper in a high strand count configuration delivers minimal resistance and maximum current transfer for 8 gauge amplifier installations. Hyper-twist construction: The hyper-twist design provides optimal flexibility for routing through tight spaces in automotive installations while maintaining structural integrity and reducing the risk of conductor fatigue over time. Translucent red matte PVC jacket: The matte translucent red PVC insulation is oil resistant and rated for extreme temperature exposure, providing durable protection suited to both underbonnet and cabin automotive environments. The red colour follows standard convention for positive power runs. 76 metre trade roll: Supplied in a 76 metre roll that can be cut to length for each application, making it well suited to trade and installer use across multiple vehicle installations from a single spool purchase.

The red colour follows standard automotive wiring convention for positive power runs. What is the difference between the SPW18TR and the SPW18TB?Both are 8 gauge OFC hyper-twist automotive power cables in a 76 metre roll with identical conductor and jacket specifications. The SPW18TR is red, suited to positive power runs, and the SPW18TB is black, suited to ground runs. Using both together provides a colour-coded power and ground cable pair for a professional installation. Can the 76 metre roll be cut to a custom length?Yes. The SPW18TR is supplied as a 76 metre roll that can be cut to the required length for each installation, making it suited to both individual vehicle runs and trade use across multiple installations. Is this cable suitable for underbonnet routing?Yes. The matte PVC jacket is oil resistant and rated for extreme temperature exposure, making the SPW18TR suitable for routing through both underbonnet and cabin environments in automotive installations. How does the SPW18TR compare to the SPW14TR and SPW10TR?All three are red OFC hyper-twist power cables with identical jacket and conductor specifications but in different gauges and roll lengths. The SPW10TR is 1/0 gauge on a 15 metre roll, the SPW14TR is 4 gauge on a 30 metre roll, and the SPW18TR is 8 gauge on a 76 metre roll. Select the gauge that matches your amplifier's power requirements.
