Speaker cable Cabletech CCA 0.75 mm, black-red, single-pair audio wire

Cabletech CCA 0.75 mm speaker cable is a single-pair audio wire with black and red color-coded insulation and a 0.75 mm² cross-sectional area. The conductor is made of copper-clad aluminum (CCA), providing a cost-effective alternative for connecting amplifiers to speakers. The design balances flexibility and reasonable current-carrying capability for typical home audio, car audio and custom in-wall or external speaker runs where moderate power transfer is required. Color-coded insulation simplifies correct polarity connection during installation.

Advantages

This Cabletech speaker cable uses a copper-clad aluminum conductor to reduce weight and cost while maintaining electrical continuity suited for low- to medium-power audio applications. The 0.75 mm² cross section offers a compact, flexible cable that is easier to route in tight spaces compared with larger gauge speaker wire. The black-red insulated pair provides clear polarity identification, reducing installation errors and ensuring consistent channel performance. The cable is suitable for visible and concealed runs in domestic and automotive environments thanks to its manageable diameter and flexibility.

Suitable for

• Connecting bookshelf or satellite speakers in home stereo systems
• Wiring speakers in car audio installations where space is limited
• Short to medium-length custom speaker runs for multi-room audio setups
• Temporary or demo audio setups where economical cabling is acceptable

Key specifications

• Conductor material: copper-clad aluminum (CCA)
• Cross-sectional area: 0.75 mm²
• Configuration: single-pair (two insulated conductors, color-coded black and red)
• Intended use: speaker / loudspeaker connections
• Flexibility: suitable for routing in confined spaces and behind equipment

How to use

Strip approximately 6–10 mm of insulation from each conductor and connect the red and black conductors to the positive and negative terminals of the amplifier and speaker respectively, maintaining correct polarity. For best contact, use appropriate connectors such as banana plugs, spade lugs or properly tightened screw terminals depending on terminal type. Keep run lengths as short as practical to reduce resistance-related power loss, and avoid sharp bends or kinks that could damage the conductor or insulation. When installing in vehicles or concealed locations, secure the cable with clips or ties to prevent movement and wear.

Usage recommendations

For optimal performance, use this 0.75 mm² Cabletech CCA speaker cable for short to moderate runs and low- to mid-power speakers. If you plan long runs or have high-power amplifiers and low-impedance speaker loads, consider a larger cross-section or pure copper conductor to minimize voltage drop and heating. Ensure terminals are clean and connections are tight to maintain reliable audio signal transfer.
