Stinger SPW18TR 8GA 76 Metre Red OFC Hyper-Twist Power Wire
True-spec 8GA OFC hyper-twist power wire in a 76-metre roll red translucent matte PVC jacket, maximum flexibility, minimal resistance, oil and temperature resistant.
Product Overview
The Stinger SPW18TR 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 red translucent matte PVC jacket, it delivers maximum current transfer with very low resistance and outstanding flexibility.
The red colour is the standard convention for positive power wiring in automotive and car audio installations. 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.
Note: The SPW18TR (red) and SPW18TB (black) are colour variants of the same 8GA OFC hyper-twist wire. Purchase both for a complete custom power and ground wiring solution at workshop scale.

Frequently Asked Questions
What is the difference between the SPW18TR and the SPW18TB?
The SPW18TR is red and the SPW18TB is black — both are 76m rolls of the same 8GA OFC hyper-twist wire with identical construction. Red is used for positive power runs and black for ground runs. Purchase both for a complete workshop power and ground wiring solution.
What is 8GA wire used for?
8GA suits amplifier systems up to approximately 600–800W RMS depending on the cable run length, as well as auxiliary battery wiring and high-current accessory feeds.
How does the SPW18TR 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 SPW18TR is a 76m bulk roll of red 8GA wire only — suited to custom lengths, multi-vehicle builds, or workshop stock.
Is this wire suitable for marine or powersports use?
The SPW18TR uses a standard matte PVC jacket rather than a marine-grade jacket. For marine or 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 an ideal workshop or commercial installer roll.
