Please note that Audiosavings audio engineers have tested this wire against 10 other brand names. We did all this research after getting complaints about certain other wires we used to carry.
• PVC outer jacket can with-stand an extreme temperature range of -40 to 220 degrees F. We also tested resistance which is really the only thing that matters. Since Rockville wires are made with around 3 times as much copper as any other wire at this price point， these wires had a much better resistance rating which means they will transfer more power to your amps than the other brands.
