Bold reliability from KnuKonceptz Kolossus 4 Gauge OFC Wiring Kit gives confidence during installation and in heavy-use systems. Is the build quality and included hardware right for your amplifier and speakers?
⚡ At a Glance
- • Power Delivery: Low-resistance 4-gauge OFC power and ground conductors support stable current flow
- • Best for: Car audio installers and enthusiasts fitting aftermarket amplifiers and subwoofers
- • Not ideal for: Users who need vehicle-specific pre-terminated harnesses or a full head unit bundle
Kit includes 5.5M 4-gauge OFC power cable and 0.9M 4-gauge OFC ground cable, plus speaker and RCA leads. Shielded RCA and included Mini-ANL fuse holder help protect circuits and reduce interference.
Consistent current for high-demand systems – with 4-gauge OFC power and ground cables
Power conductor is 4-gauge oxygen-free copper, supplied as a 5.5M blue power lead and a 0.9M black ground lead. Larger cross-section and OFC construction reduce resistance and help maintain voltage under load.
Stable voltage to an amplifier reduces strain and supports higher output. Suitable for installers aiming to power medium to high-power amplifiers reliably.
Easier routing in tight spaces – with 12-gauge ultra-flex speaker cable
Speaker runs use 6M 12-gauge Ultra Flex OFC cable designed for pliability during installation. Flexible insulation allows neat bends and cleaner runs without kinking.
Simpler installation behind panels and through grommets reduces labour and the need for extra joins. Longer continuous runs lower the chance of signal loss from poor connections.
Cleaner signal and line protection – with shielded OFC RCA and Mini-ANL fuse holder
Includes a 5M OFC Bassik coaxial shielded RCA cable for two channels and a Mini-ANL fuse holder fitted with a 120A MANL fuse. Shielding limits electromagnetic interference while the inline fuse protects the power feed.
Reduced background noise and interference lead to clearer audio, especially in electrically noisy vehicles. Inline fusing helps protect wiring and amplifier in the event of a short.
✨ The 4 Key Reasons for KnuKonceptz Kolossus 4 Gauge OFC Wiring Kit
