Stinger SPW14TB 30 Meter Roll 4GA Black Cable

Stinger SPW14TB 4GA 30 Metre Black OFC Hyper-Twist Power Wire

True-spec 4GA OFC hyper-twist power wire in a 30-metre roll black translucent matte PVC jacket, maximum flexibility, minimal resistance, oil and temperature resistant.

Product Overview

The Stinger SPW14TB is a 30-metre roll of 4GA bulk power wire for amplifier and 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.

The black colour is the standard convention for negative (ground) wiring in automotive installations. The PVC jacket is oil resistant and rated for extreme temperatures.

The SPW14TB (black) and its red companion (if available) are the 4GA equivalent of the SPW10TR/SPW10TB 0GA pair. The SPW14TB is typically used for ground runs, or as power wire where a custom black-finish installation is preferred.

Frequently Asked Questions

What is 4GA wire used for?

4GA is a large-diameter power cable suited to amplifier systems up to approximately 1,500W RMS depending on cable run length. It is also used for high-current DC accessories and auxiliary battery installations.

How does the SPW14TB differ from the SK4241 wiring kit?

The SK4241 is a complete 4GA wiring kit with a fixed 5.5m power cable, ground wire, fuse holder, hardware, and remote wire. The SPW14TB is a 30m bulk roll of 4GA black wire only — suited to custom cable lengths or multi-amplifier installations requiring more cable than the fixed-length kit provides.

Is the SPW14TB suitable for use as the positive power wire?

Yes. While black is conventionally used for ground wiring, there is no technical reason it cannot be used for the positive power run if a uniform black finish is desired. Clearly label or heat-shrink the ends to indicate polarity if using black wire for positive runs.

Is this wire suitable for marine or powersports use?

The SPW14TB uses a standard matte PVC jacket rather than a marine-grade jacket. For marine installations, the Stinger SEASW4125 or SEASW8125 marine siamese pair wire is recommended depending on required gauge.

Is 30m sufficient for most installations?

30m provides enough 4GA cable for approximately four to six standard single-amplifier installations (typically requiring 5–7m each), making it well-suited to workshop or installer bulk stock.
