good places to ground amplifier under passenger seat in s14

[rb25crazy]

hey guys

just like the title says i wanna know of some good places to ground amplifier under passenger seat in s14.

also, what kind of a drill size would i need to drill a hole big enough for a 8 gauge ground. kinda hoping there is already hole somewhere i can just use without drilling a hole.

and how would i place this nut above the ground would i put the razor saw thing on top of the ground? or use the smooth side?

i can't help you with whatever that thing is.
