soundco speaker cable, model 2040, 100-meter loop, has two layers of PVC coating, in addition to protecting the wire strands
 inside the cable, to maintain high tolerance in cold and heat. The thickness of the cover used is 6 + 6 mm, the use of pure 
copper in the Sandco speaker cable and the number of strands above the 254 + 254 wire have been effective in conducting and 
not reducing the ohm in long distances.
