Speaker Cable Cabletech KAB0389 CCA conductor 0.50 mm, black-red

Cabletech KAB0389 speaker cable features a copper-clad aluminum (CCA) conductor with a 0.50 mm cross-section per strand and a black-red jacket. It is intended for connecting loudspeakers and audio equipment in home or commercial settings where a lightweight, cost-effective cable is required for low- to moderate-power audio signals. The two-colour jacket simplifies polarity identification during installation and maintenance.

Advantages

The Cabletech KAB0389 offers a balance of affordability and functional performance by using CCA conductors that reduce weight and cost compared with pure copper alternatives. The 0.50 mm strand size is suitable for short runs and typical domestic speaker layouts. The contrasting black and red insulation on the two conductors makes wiring quicker and reduces the risk of reversed polarity. The cable's flexible jacket supports routing through walls, conduits, or around furniture during installation.

Suitable for

• Connecting bookshelf, satellite or small floorstanding speakers to amplifiers in home audio systems
• Short to moderate length speaker runs in living rooms, offices, classrooms or retail spaces
• Replacing or extending existing speaker wiring where high-cost copper cable is not required
• Installations where clear polarity marking (black/red) is helpful for multi-speaker setups

When it may not be suitable

This cable is not intended for high-power professional loudspeaker systems or long-distance runs where voltage drop and power loss become significant. For installations that demand maximum conductivity, lower resistance and the best possible signal integrity, a solid copper conductor with larger cross-section is recommended. Also avoid using this cable in locations that require specific fire ratings or in-wall certifications unless the cable meets those local standards.

Key specifications

• Conductor type: copper-clad aluminum (CCA)
• Strand cross-section: 0.50 mm per strand
• Conductor configuration: twin conductors with contrasting insulation
• Colour: black and red jacketed conductors for polarity identification
• Primary use: speaker/ audio signal wiring

How to use

Strip an appropriate length of insulation from each conductor and connect to the speaker terminals and amplifier outputs, observing polarity (red = positive, black = negative). Ensure connections are tight and free of stray strands that could short. For runs through walls or conduits, use grommets or protective sleeves to prevent abrasion of the jacket. Keep cable lengths as short as practical for higher power applications to minimise resistance and signal loss.

What to consider before purchase

• Required cable length and total run distance to estimate power loss and voltage drop
• Power handling needs of your speakers and amplifier to determine if CCA and 0.50 mm strand size are sufficient
• Whether in-wall installation requires compliance with local fire or building codes
• Whether you prefer solid copper conductors for maximum conductivity and lower resistance

Usage recommendations

Use this Cabletech KAB0389 cable for short to moderate speaker runs in domestic and light commercial installations. For best results, match cable length and conductor size to your system's power and impedance requirements, maintain correct polarity using the red/black marking, and protect the cable where it passes through structural elements.
