Automotive Cable Cabletech 2Ga OD12mm CU+AL — 2 AWG, 12 mm OD, Copper+Aluminum

Cabletech 2Ga OD12mm CU+AL is an automotive power cable designed for vehicle electrical and audio installations that require a heavy-gauge supply line. With a 2 AWG conductor size and approximately 12 mm outside diameter, this cable combines copper and aluminum conductors to deliver high current capacity in a compact profile suitable for battery-to-amplifier runs, starter connections and other high-current circuits in cars, trucks and marine vehicles.

Advantages

The cable offers a balance between conductivity and weight by using copper plus aluminum construction, providing reliable current delivery with reduced mass compared to full-copper alternatives. Its 2 AWG cross-section supports high-current applications while the ~12 mm outer diameter simplifies routing through engine bays and tight cable channels. The construction is tailored for automotive environments, resisting everyday mechanical stresses encountered in vehicle installations.

Suitable for

• Battery-to-amplifier power feeds for car audio systems
• Starter motor and high-current engine circuits
• Aftermarket alternator or high-current accessory wiring
• Power distribution between battery and fuse/DB blocks

Key specifications

• Conductor type: copper + aluminum composite
• Conductor size: 2 AWG
• Approximate outside diameter: 12 mm
• Intended use: automotive power / audio installations
• Flexibility: suitable for routing through vehicle cable channels and grommets

How to use

Plan the cable route to minimize length and avoid sharp edges, heat sources and moving parts. Use appropriately sized terminals or lugs that are compatible with composite CU+AL conductors and ensure secure mechanical and electrical connections; where recommended, use crimping tools rated for the chosen lug type and consider solder or conductive paste only if specified by terminal manufacturer. Protect exposed sections with heat-resistant sleeving, conduit or grommets and secure the cable with clamps or ties at regular intervals to prevent abrasion and fatigue. Verify polarity and fuse the supply near the battery with an appropriate fuse or breaker sized for the expected current.

Usage recommendations

For best results in high-current automotive installations, select terminals and connectors rated for composite conductors and follow manufacturer guidance for crimping and protection. Keep cable runs as short as feasible, fit an inline fuse close to the battery, and avoid routing next to hot exhaust components. If in doubt about current capacity or installation practices, consult a professional installer to ensure safe and reliable operation.
