I just have the power cable for battery, lost the ground cable.. Can I cut from power cable and use for ground? Are they the same thing or different cables.??
the only difference is the plastic coating (the color)- as long as you don't mix up the pos and neg at the amp you are fine
for the most part, all wire is the same. Just a bunch of stands of copper and sometimes aluminum. So yes, go ahead and use the power cable.
yes you could use the power cable for the ground because the power cable and ground cable are the same material, as long as both the same guage size is good to connect. For the ground should be as short as possible to the chassis of the car. ground cable just as important as power to get the circuit DC power circulation.
