Stinger SK4201 4000 Series 1/0 Gauge Amplifier Power Wiring Kit with ANL Fuse Holder and Pre-Terminated Ring Terminals The SK4201 from Stinger is a 1/0 gauge amplifier power wiring kit from the 4000 Series range, designed for car audio systems up to 3400 watts or 250 amps. The kit includes 5.5 metres of matte red hyper-twist power wire, 0.9 metres of ground wire, a remote turn-on wire, an ANL fuse holder, a 250 amp fuse, pre-installed crimp ring terminals, and all supporting installation hardware. Product overview The Stinger 4000 Series is built for high-demand car audio systems where power delivery, noise rejection, and signal integrity are critical. The SK4201 uses true-spec tinned oxygen-free copper 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. All power connections are pre-terminated with 1/0 gauge crimp ring terminals, removing the need for field termination of the main power connections. The included SPD5201 ANL fuse holder and 250 amp Shoc-Krome ANL fuse provide rated circuit protection for systems drawing up to 250 amps. Supporting hardware including a firewall grommet, self-drilling mounting screws, a butt connector, and wire ties are all included, making the SK4201 a complete wiring solution for high-powered installations.
