I have seen some pictures on installing wires to the battery from an amp. The only confusion i have is the grounding wire. I know the amp has a ground wire to the chassis/body. Is there a ground wire for anything else?

On the monster cable installation kit, it says there is a ground wire for the battery when you are hooking up your cable.

Sorry i am very new to this, and basically i need to know the full wiring instructions for amp to battery...vice versa.
