Speaker cable Cabletech CCA 1.5 mm², black-red, single-pair

Cabletech CCA 1.5 mm² speaker cable in black and red is a single-pair cable designed for connecting amplifiers, receivers and loudspeakers in home audio systems. The conductors use CCA (copper-clad aluminum) to provide a balance between electrical conductivity and reduced weight compared with solid copper. The cable's 1.5 mm² cross-sectional area supports typical low- to medium-power audio installations and multiroom wiring where a durable, color-coded pair simplifies polarity identification.

Advantages

This speaker cable combines the lower mass of aluminum with a copper surface layer to improve contact conductivity while keeping material costs and weight down. The black-red insulation on separate conductors makes installation and polarity marking straightforward, reducing wiring errors. The 1.5 mm² conductor area offers adequate current-carrying capacity for many domestic loudspeaker setups and short to moderate cable runs.

Suitable for

• Home stereo systems and bookshelf speakers
• Multiroom audio installations with short to medium cable runs
• DIY speaker building and custom wiring projects
• Connections between receivers, amplifiers and passive speakers

Key specifications

• Conductor material: copper-clad aluminum (CCA)
• Conductor cross-sectional area: 1.5 mm²
• Configuration: single pair (two insulated conductors, color-coded black and red)
• Insulation: color-coded polymer jackets for polarity identification
• Intended use: low- to medium-power audio signal transmission for speakers

How to use

Strip appropriate lengths of insulation from each conductor and attach to speaker or amplifier terminals, observing correct polarity (red to positive, black to negative). Use suitable connector types (banana plugs, spade lugs, or bare wire) depending on terminal design and installation preference. For best performance, keep cable runs as short as practical, avoid tight bends, and ensure secure, corrosion-free terminations.

Usage recommendations

For reliable performance, use this 1.5 mm² CCA cable on short to medium runs and in systems where impedance and power requirements match the conductor size. Avoid long, high-power runs where lower-resistance pure copper cable is preferable. Keep connections clean and mechanically secure; if frequent disconnection is expected, use appropriate plug or lug terminations to reduce wear on exposed conductors.
