MX transparent speaker cable is used to make the electrical connection between loudspeakers and audio amplifiers. MX speaker cable consists of two electrical conductors which are individually insulated. MX transparent speaker cable will transfer high quality sound signal without loss.Use this wire to connect speakers to your stereo or home theater receiver. Use this with any 12 Volt or home project. Rated 20 C to 60 C (6 to 80 Volts).?Note : Copper Clad Aluminum (CCA) wires do not follow the American Wire Gauge standard (AWG).?AWG is developed for electrical resistance classification of Oxygen Free Copper (OFC) wires. High current application specifying AWG standard assumes the wire is OFC.?Same conductor area CCA has higher resistance than OFC making AWG classification invalid. CCA wires are developed for low current applications (e. g. signal processing). As a rule of thumb, reduce CCA gauge size by 2 to achieve similar electrical resistance as OFC wires.
