Speaker cable Cabletech CCA 2.0mm — 2-conductor audio cable, copper-clad aluminum conductor

Cabletech CCA 2.0mm speaker cable is a two-conductor audio cable with copper-clad aluminum (CCA) conductors and a 2.0 mm² cross-section per conductor. It is intended for loudspeaker wiring in home audio systems, multiroom installations and certain car audio setups where a lightweight and cost-effective conductor is acceptable. The cable balances economical material choice with basic electrical performance required for short to medium speaker runs.

Advantages

The Cabletech CCA 2.0mm speaker cable offers a lower weight compared with solid copper of equivalent cross-section and typically comes at a lower price point, which reduces installation costs for long runs or multiroom projects. Copper cladding improves solderability and corrosion resistance relative to bare aluminum conductors. The 2.0 mm² conductor area delivers sufficient current capacity for many bookshelf and small to medium floor-standing speakers at moderate listening levels.

Suitable for

• Home loudspeaker connections over short to medium distances
• Multiroom audio wiring where many runs are required
• Car audio installations where reduced weight is desired and runs are short
• Budget-conscious speaker system installations

When it may not be suitable

For long cable runs, very low impedance speakers, or high-power amplifiers driving demanding speaker loads, copper conductors of larger cross-section typically provide lower resistance and better long-term performance. High-end audiophile systems and professional installations that require the lowest possible signal loss and maximum durability may prefer pure copper or higher-spec cabling.

Key specifications

• Conductor type: copper-clad aluminum (CCA)
• Number of conductors: 2 (bi-wire/standard speaker pair)
• Conductor cross-section: 2.0 mm² per conductor
• Intended use: loudspeaker/audio signal wiring
• Typical installation: home audio, multiroom, car audio (short runs)

How to use

Strip an appropriate length of the outer insulation to expose the two conductors, taking care not to nick the metal strands. Identify polarity by marking or by the printed/coloured side and connect consistently to amplifier positive (+) and speaker positive (+) terminals. For reliable connections, use proper banana plugs, spade lugs, or firmly insert bare wire into spring or screw terminals. Avoid excessively long unprotected runs and secure the cable to prevent mechanical strain on terminations.

What to consider before purchase

• Required run length and whether 2.0 mm² provides acceptable resistance for your setup
• Compatibility with amplifier and speaker terminal types (banana, spade, bare wire)
• Preference for pure copper conductors if minimal resistance and highest durability are priorities

Usage recommendations

Use Cabletech CCA 2.0mm for short to medium speaker runs in home or car systems where budget and weight are considerations. Maintain consistent polarity, keep runs as short as practical for higher power systems, and secure terminations with appropriate connectors to minimize contact resistance and improve reliability.
