Stinger SK4681 8GA 4000 Series Power Wire Kit With RCA

Stinger SK4681 4000 Series 8 Gauge Amplifier Power Wiring Kit with SI4217 2-Channel RCA Interconnect

The SK4681 from Stinger is an 8 gauge amplifier power wiring kit from the 4000 Series range, rated for car audio systems up to 600 watts or 60 amps. It bundles the SK4281 wiring kit specification with the SI4217 4000 Series 2-channel RCA interconnect (5.2m), providing both the power wiring and RCA signal cable needed for a complete amplifier installation in a single purchase.

Product overview

The Stinger 4000 Series is built for car audio systems where power delivery, noise rejection, and signal integrity matter. The SK4681 uses true-spec tinned oxygen-free copper hyper-twist conductors throughout, ensuring maximum current transfer without the resistance and corrosion issues that affect lesser cable constructions. The matte finish hyper-twist wire construction provides excellent flexibility during installation while maintaining a clean, professional appearance in the finished result.

Bundling the power wiring with the SI4217 RCA interconnect removes the need to purchase a separate signal cable, making the SK4681 the complete solution for an 8 gauge amplifier installation. All power connections are pre-terminated with 8 gauge crimp ring terminals, and the SPD5101 AGU fuse holder and 60 amp AGU fuse provide correctly rated circuit protection. Supporting hardware including a firewall grommet, self-drilling mounting screws, a butt connector, and wire ties are all included.

Features and benefits

Technical specs

Frequently asked questions

What is the difference between the SK4681 and the SK4281?
Both are 8 gauge 4000 Series wiring kits with identical power wiring specifications. The SK4681 additionally includes the SI4217 4000 Series 2-channel RCA interconnect (5.2m). If you already have a suitable RCA cable, the SK4281 is sufficient. If you need both the power wiring and a quality RCA cable, the SK4681 provides both in a single purchase.

What RCA cable is included with the SK4681?
The SK4681 includes the Stinger SI4217, a 4000 Series 2-channel RCA interconnect measuring 5.2 metres. It is from the same 4000 Series product family as the power wiring in this kit.

Are the ring terminals pre-installed on the power wire?
Yes. The 8 gauge crimp ring terminals are pre-installed on the power wire, providing reliable, factory-grade terminations on the main power connections without the need for field crimping.

Does this kit include a remote turn-on wire?
Yes. An 18 gauge matte blue remote turn-on wire measuring 5.2 metres is included, connecting to the head unit's remote output to activate the amplifier when the head unit powers on.

Is the 0.9m ground wire long enough for my installation?
The 0.9 metre ground wire is sufficient for grounding to a chassis point close to the amplifier. For amplifiers mounted further from a suitable chassis ground point, a longer ground cable will need to be sourced separately. Contact us if you need guidance on selecting the correct ground cable length for your installation.
