Decided to start learning how to do some of my own work and figured the big 3 was as good a place as any.
I looked for the extra wires connecting battery -alt, and battery-chassis & chassis -engine block but didnt see any.
took these pics-----
BTW: what does the fuse mean?
I'm not having any of the problems that the big 3 would fix, so my question is do I need to do it anyway?
I have one amp a JL A6450, but might add one more small one 250w or less.
