0 GAUGE CCA BIG 3 UPGRADE KIT

HELP YOUR VEHICLE'S CHARGING SYSTEM DELIVER POWER MORE EFFECTIVELY

If you are running a powerful car audio system, upgraded alternator or additional electrical accessories, your factory power and ground cables can become a restriction.

The 0 Gauge CCA Big 3 Upgrade Kit replaces or supplements the three main charging system connections with larger cable to help improve current flow and reduce unnecessary voltage drop.

It is one of the most common electrical upgrades for vehicles running high powered amplifiers, subwoofers and upgraded charging systems.

WHAT IS THE BIG 3 UPGRADE?

The Big 3 upgrade increases the cable size of the three main electrical connections in your vehicle:

• Alternator positive to battery positive

• Battery negative to chassis

• Engine block to chassis or battery negative

Upgrading these connections can help reduce resistance in the charging system and give demanding electrical equipment a stronger path for current flow.

BETTER POWER PATHS HELP YOUR ELECTRICAL SYSTEM WORK MORE EFFECTIVELY.

WHY UPGRADE THE FACTORY WIRING?

Factory electrical wiring is designed around the original equipment fitted to the vehicle.

Once you add powerful amplifiers, subwoofers, upgraded alternators or other high current accessories, the electrical demand can increase significantly.

A Big 3 upgrade can help with:

• Reducing voltage drop

• Improving current flow

• Supporting high powered amplifiers

• Supporting upgraded alternators

• Improving power and ground connections

• Creating a stronger electrical foundation for your audio system

It does not create additional alternator output, but it can help your charging system deliver available current through larger connections.

0 GAUGE CCA CABLE

This kit uses 0 Gauge Copper Clad Aluminium cable, commonly known as CCA.

The larger cable size provides a practical and affordable option for upgrading factory power and ground connections.

CCA offers a lower cost alternative to pure copper wiring while still being suitable for many Big 3 applications when correctly sized and installed.

For extremely high current systems, 0 Gauge OFC may be the better choice.

3 PIECE COMPLETE BIG 3 KIT

The kit includes three 1.2 metre 0 Gauge cables, giving you the main cables required to complete a Big 3 electrical upgrade.

Each cable is pre crimped on one end, making installation faster while still allowing you to cut and terminate the opposite end to suit your specific vehicle.

KIT INCLUDES

3 x 1.2 Metre 0 Gauge CCA Cables

Includes:

• 1 Positive cable

• 2 Ground cables

One Side Pre Crimped

Each cable has one terminal already installed to help reduce installation time.

3 Extra Cable Lugs

Allows the remaining ends to be terminated according to the required cable length and mounting location.

Insulation Sleeves Included

Provides a cleaner and more protected finish around the cable terminations.

PERFECT FOR HIGH POWER CAR AUDIO

This Big 3 kit is ideal for:

• High powered amplifiers

• Subwoofer systems

• Car audio builds

• Upgraded alternators

• Additional battery systems

• Vehicles experiencing electrical voltage drop

• Custom electrical upgrades

• High current accessories

If your audio system is demanding more current than the factory electrical system was originally designed to support, upgrading the main power and ground connections is a smart place to start.

WHY VOLTAGE DROP MATTERS

Your amplifier needs stable electrical power to perform properly.

Excessive resistance in the charging system can contribute to voltage drop when electrical demand increases.

Lower voltage can mean:

• Reduced amplifier output

• Earlier amplifier clipping

• Increased electrical stress

• Dimming lights

• Reduced system performance

Improving the main electrical connections helps give current a better path between the alternator, battery, engine and chassis.

A POWERFUL AUDIO SYSTEM NEEDS A STRONG ELECTRICAL FOUNDATION.

DESIGNED TO FIT YOUR VEHICLE

Every vehicle has different cable lengths, mounting locations and terminal requirements.

That is why each cable is supplied at 1.2 metres long, with one end already crimped and the other end ready to be finished to suit your vehicle.

You can cut the cable to the required length and use the supplied lug to create a cleaner custom fit.

IS THE BIG 3 ENOUGH FOR MY SYSTEM?

The Big 3 upgrade helps improve the main electrical connections, but it does not increase the output capability of your alternator or battery.

Very high power systems may also require:

• Higher output alternator

• Upgraded battery

• Additional battery capacity

• 0 Gauge OFC wiring

• Proper amplifier power wiring

• Correct fuse protection

The complete electrical system should be matched to the amount of power your audio system requires.

BUILD THE ELECTRICAL SYSTEM BEFORE CHASING MORE POWER

Adding a bigger amplifier without improving the electrical system behind it can limit the performance you actually receive.

A Big 3 upgrade is a simple way to strengthen the foundation of your charging system before pushing your audio system harder.

BETTER CONNECTIONS. LESS VOLTAGE DROP. STRONGER ELECTRICAL SUPPORT.
