The cable has a black PVC sheath on one core and a white polarity line on the second, making it straightforward to maintain correct phase when wiring multiple speakers or running long parallel runs.\u003c\/p\u003e\n\u003cp\u003eDesigned for light-duty audio installations where runs do not exceed 10-15m per speaker and power handling stays below 50W, the cable suits background music systems, small PA setups, multi-room audio distribution and budget home hi-fi. The figure 8 profile makes the cable easy to route along skirting boards, under carpets or through cable trays without the stiffness of round twin-core cable. The 100m reel provides enough length for a typical 4-6 zone commercial audio system or a domestic whole-house distribution with sensible routing.\u003c\/p\u003e\n\u003cp\u003eThe 2.0 x 4.0mm flat profile is thin enough to fit behind most wall plates and under doors without creating trip hazards or visible floor bulges. The copper\/CCA conductor blend keeps cost down while maintaining acceptable conductivity for the 1.0A maximum current rating. For runs longer than 15m or higher-power applications, a thicker cable (0.5mm² or 0.75mm²) is recommended to avoid voltage drop and power loss.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eConductor\u003c\/td\u003e\n\u003ctd\u003eCopper\/Copper Clad Aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e100m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSA\u003c\/td\u003e\n\u003ctd\u003e0.18mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrands\u003c\/td\u003e\n\u003ctd\u003e2 x (4 x 0.18mmØCu + 3 x 0.18mmØCCA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e2.0 x 4.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSheath\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePolarity\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacked quantity\u003c\/td\u003e\n\u003ctd\u003e12 reels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent\u003c\/td\u003e\n\u003ctd\u003e1.0A max.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the maximum speaker distance this cable can handle?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFor speakers up to 50W, keep runs under 10-15m to avoid voltage drop.
