Default Help with ground

I know this has been covered before but I cant seem to locate the grounding point to ground 2 alpine amps, I know it is somewhere under the outer passenger tail light. Can someone guide me where it is and how to get the wire to it (0 gauge). I grounded the amps but they seem to be overheating and protection light is on so I'm guessing the issue is a grounding problem. I have them grounded to a screw under the carpet where it looks like its connected to the frame. I shaved it down to expose the metal.

Do you have more than one amp? I have 2 Class AB amps that suck lots of juice. I got the 270XP alternator thinking it was the amperage, turns out it's something else, Im guessing ground.

I have 2, one AB and one D. Each mounted behind a seat, this was the shortest route and are factory ground points.

Directly below outer tail light on the passenger side. There's a plastic piece that sits atop the stud holding the wiring harness.

Not sure why the pics were rotated 90 degrees counter-clockwise in the posting process.

How do I find it? Do I need to remove the outer taillight and see it from outside of car or is it accessible from the inside?

Pics were taken with the tail lights removed and looking straight down.
