Its a Belden 83802 I got from Audiyo a few years ago ,a stiff red teflon with shield and two conductors both 12 guage inside . I bought an extra 16 guage red teflon wire from Lees electronics and wrapped it on the outside for ground sleeved up with red braided plastic ,red heatshrink on both ends and bolted on the marincos plugs. Made four 6ft power cables. Theres a 83803 thats three conductor but I thought the two conductor version with outside ground wire was better cause its better flexibility to use. But its up to you .
