[QUOTE="forbidden, post: 715170, member: 552189"] If only I could reach through a computer and smack some people. Resistance on the ground return causes major headaches. It is not about the size or amount of metal in the return, it is about the resistance that is generated by running large amounts of current through whatever blend of metals they use, then through glued together unibodys panels, then through spot welds and finally make it's way to your amp. Electricity is an algebra equation, what you do to one side you must do to the other. If you have a monster system with a monster current draw you are not going to hook up to your fuse panel are you? So why treat the most important wire in your system with the least amount of respect. A proper ground (the 4th wire in the BIG 3), will have a return resistance reading of below 1/2 ohm. If the ground return resistance cannot be made to get below 1/2 ohm then it is highly advisable to ground direct to the battery, the same way that you hooked up the power wire. [/QUOTE]
