Stinger SPW18TB 8GA 76 Metre Black OFC Hyper-Twist Power Wire
True-spec 8GA OFC hyper-twist power wire in a 76-metre roll black translucent matte PVC jacket, maximum flexibility, minimal resistance, oil and temperature resistant.
Product Overview
The Stinger SPW18TB is a 76-metre roll of 8GA bulk power wire for amplifier and high-current DC electrical installations. Built with high-strand-count finely stranded OFC (oxygen-free copper) and a black translucent matte PVC jacket, it delivers maximum current transfer with very low resistance and outstanding flexibility.
At 76 metres, this is the highest-volume roll in the Stinger bulk power wire range suited to workshop stock, commercial installer use, or large-scale multi-vehicle builds.

Frequently Asked Questions
What is 8GA wire used for?
8GA is suited to amplifier systems up to approximately 600–800W RMS depending on the cable run length. It is also used for auxiliary battery wiring, accessory feeds, and other high-current applications where 4GA would be oversized.
How does the SPW18TB differ from the SK4281 wiring kit?
The SK4281 is a complete 8GA wiring kit with a fixed 5.5m power cable, ground wire, fuse holder, and hardware. The SPW18TB is a 76m bulk roll of black 8GA wire only — suited to custom cable lengths, multi-vehicle installations, or workshop stock.
Is the SPW18TB suitable for use as the positive power wire?
Yes. While black is conventionally used for ground wiring, it can be used for the positive power run if a uniform black finish is preferred. Clearly label or heat-shrink the ends to indicate polarity if doing so.
Is this wire suitable for marine or powersports use?
The SPW18TB uses a standard matte PVC jacket rather than a marine-grade jacket. For marine or outdoor powersports installations, the Stinger SEASW8125 8GA marine siamese pair wire is recommended.
Is 76m sufficient for most installations?
76m provides enough 8GA cable for approximately ten to fifteen standard single-amplifier installations (typically 5–7m each), making it a high-volume workshop or commercial installer roll.
