[QUOTE="joetama, post: 1498881, member: 564641"] You develop more of a voltage difference running a cable from under the hood of your car to the amp than directly connecting the ground to the frame. And if you have the ol' big 3 properly installed then the frame should be the lowest point of ground all over the vehicle. All of your grounds should run to the same place or you can develop voltage differences that will cause background noise. [/QUOTE]
