Speaker cable Cabletech CCA 0.20 mm black-red — two-conductor audio wire

Cabletech CCA 0.20 mm black-red is a two-conductor speaker cable designed for audio signal transmission in home and small commercial installations. The cable features copper-clad aluminium (CCA) conductors made up of 0.20 mm cross-sectional strands and a distinctive black-red jacket to simplify polarity identification. It is intended for short-to-medium length connections between speakers, amplifiers and audio receivers where a lightweight, cost-effective wiring solution is required.

Advantages

The Cabletech CCA construction provides a balance between conductivity and lower material cost compared with pure copper cables, while the 0.20 mm strand size offers flexibility for easy routing and termination. The dual-color insulation (black and red) makes polarity identification straightforward during installation. The cable’s two-conductor layout is compatible with most consumer speaker terminals and standard banana plug, spade or bare-wire connections.

Suitable for

• Connecting bookshelf or satellite speakers to amplifiers and receivers
• Home theater setups with short-to-medium speaker runs
• Audio projects and temporary or prototype installations

Key specifications

• Conductor type: copper-clad aluminium (CCA)
• Strand size: 0.20 mm per strand
• Cable configuration: two conductors (black and red insulation)
• Intended use: low-voltage audio/speaker signal transmission
• Termination compatibility: bare wire, banana plug, spade connector

How to use

Strip a short length of insulation from each conductor, taking care not to nick the strands. Twist the exposed strands and insert into the speaker or amplifier terminal or attach a chosen connector such as a banana plug or spade. Observe polarity: connect the red-insulated conductor to the positive terminal and the black-insulated conductor to the negative terminal. Ensure secure mechanical and electrical contact and avoid sharp bends or kinks along the cable run. For runs longer than typical home distances, consider cable gauge and power handling when planning installation.

Usage recommendations

Use this Cabletech speaker cable for short-to-medium length runs in home audio and small installations. For critical long-distance runs or high-power professional systems, evaluate a thicker copper conductor for improved conductivity and lower resistance.
