I need a little guidance I intend to wire a car amp directly to a 12v battery, but not in a car.
Im not sure what to do with the ground wire since i dont have a car body to attach to, though somebody explained that i could emulate one by sandwiching aluminium and copper plates with the ground wire between. Also, what do i do with the negative connection on the battery.
Can I connect the ground wire to the negative on the battery?
