SKITY CAR AUDIO 70mm² (00 AWG) Ultimate Big 3 Electrical Upgrade Kit

Skity Car Audio 70mm² (00 AWG) Ultimate Big 3 Electrical Upgrade Kit

​Is your voltage dropping every time the bass hits? Are your headlights dimming or your digital dash flickering?

​Your factory wiring loom was built to handle a stock horn and headlights—not a high-current, heavy-hitting aftermarket amplifier. If you are pushing 2,000W to 5,000W+ RMS, a standard 4 AWG or even basic 50mm² kit just won't cut it. You are starving your amplifiers, creating heat, and destroying your equipment.

​The Skity Audio 70mm² Ultimate Big 3 Upgrade Kit is the nuclear option for your car's electrical system. Packed with massive, industrial-grade 70mm² (00 AWG) Pure Oxygen-Free Copper (OFC), this kit replaces your vehicle’s restrictive factory grounds and alternator charge lines to completely maximize current flow and lock down your voltage.

​Why 70mm² Pure OFC?

​Zero Aluminum, All Power: Many cheap kits use Copper-Clad Aluminum (CCA), which corrodes easily and resists power. Our wire is 100% Pure Oxygen-Free Copper, offering maximum conductivity and flexibility.

​Massive Current Handling: 70mm² cross-sectional area means zero bottlenecking. It allows your alternator to dump raw power straight into your battery bank without restriction.

​What’s In The Box?

​We don’t do cheap plastic or thin terminals. Every component in this kit is selected for heavy-duty, competition-grade builds:

​2 Metres - Crimson Red 70mm² Premium OFC Wire: Perfect length for your high-output alternator-to-battery positive charge line.

​4 Metres - Stealth Black 70mm² Premium OFC Wire: Plenty of cable to upgrade both your main chassis ground (battery negative to chassis) and your engine block ground (engine block to chassis).

​8x Heavy-Duty 70mm² Copper Lugs (M8 / 8mm Thread): Pure copper lugs designed for maximum surface area contact and rock-solid terminal clamping.

​1x Heavy-Duty Inline ANL Fuse Holder: High-grade, impact-resistant fuse block to safely protect your upgraded alternator line.

​The Benefits

​Instant Voltage Stabilization: Stops headlights dimming and keeps your amps running at peak efficiency.

​Better Bass Response: Amplifiers can hit harder and cleaner when they aren't starved of current.

​Cooler Operations: Reduces electrical resistance, protecting your expensive alternator from burning out prematurely.

​Note: Wire is supplied uncut so you can tailor the lengths perfectly to your specific engine bay layout. Professional hydraulic crimping or soldering is highly recommended for the 70mm² lugs.
