This is a 1/0 gauge high-power grounding cable that can be used for cars, motorcycles, etc. Length: 60cm Limited quantity available while supplies last. The cable uses Dragon Gold, handled by the Japanese manufacturer, Jean Line. Crimping is done using hydraulic tools, and we have prioritized quality over inexpensive gold plating. The terminal manufacturer may change depending on stock availability. (The photo shows terminals compatible with M10 bolts. Usually, M8 bolt terminals are used.) It can be used in various ways for tuning, such as reinforcing the battery's negative terminal, grounding from the engine to the body, and grounding from the muffler to the body. It is more effective to ground at one point with this cable than to route various thin ground wires. Effects include: Improved sound quality of car audio Changes in engine feeling Changes in exhaust resistance of the muffler Improved stability of headlight brightness, etc. Why not try connecting it in various places and enjoy the changes in your car? Marks are placed on the terminals. Electricity flows from the terminal with the mark to the terminal without the mark.
