Each conductor is built from 13 x 0.18mm copper strands and 13 x 0.1mm CCA strands, giving a combined cross-sectional area of 0.66mm² and a maximum current rating of 6A.\u003c\/p\u003e\n\u003cp\u003eDesigned for everyday audio wiring in domestic, commercial and light installation applications, the cable suits speaker runs up to 20m for background music systems, PA distribution, and home audio installations where high-power audiophile-grade cable is not required. The figure-8 format keeps both conductors together during installation, preventing tangling and simplifying cable management behind wall plates or under floors. The black polarity line running along one conductor identifies positive and negative terminals without needing to strip and inspect the conductors.\u003c\/p\u003e\n\u003cp\u003eThe grey sheath provides a neutral appearance against white walls and skirting boards, and the 2.5 x 5mm profile is low enough to be concealed under carpets or behind trunking without causing visible ridges. The 100m reel length covers most domestic or small commercial installations without requiring mid-run joints, which can introduce signal loss or impedance mismatches. The copper\/CCA hybrid conductor keeps the cable affordable while maintaining adequate conductivity for typical 8-ohm speaker loads at moderate power levels.\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\u003e0.66mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrands\u003c\/td\u003e\n\u003ctd\u003e2 x (13 x 0.18mmØCu + 13 x 0.1mmØCCA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e2.5 x 5.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSheath\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePolarity\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacked quantity\u003c\/td\u003e\n\u003ctd\u003e8 reels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent\u003c\/td\u003e\n\u003ctd\u003e6.0A 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 speaker impedance and power level does this cable suit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 0.66mm² CSA and 6A maximum current rating suit 8-ohm speakers at moderate power levels, typically up to 50-70W RMS per channel over runs of 10-20m.

For outdoor speaker runs the cable should be run inside conduit or trunking to protect it from UV degradation and moisture ingress.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between copper and CCA conductors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCopper-clad aluminium (CCA) has an aluminium core with a thin copper coating. It's lighter and cheaper than pure copper but has higher resistance, which can introduce signal loss over long runs. This cable uses a hybrid construction with both copper and CCA strands, balancing cost and conductivity for typical domestic audio applications.\u003c\/p\u003e","brand":"AVSL","offers":[{"title":"Default Title","offer_id":45313495728395,"sku":"801.422UK","price":20.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/801422UK_LD1_3728159f-25e2-48ca-bd9f-ff8afd000b08.jpg?v=1715194570","url":"https:\/\/niori.co.uk\/products\/mercury-fig-8-speaker-cable-2-x-26-strand-grey-black-100m-reel","provider":"Niori","version":"1.0","type":"link"}
