I grounded my amps in my 94 Grand Marquis to the frame from the trunk.

I grounded mine to the bolt on the back of my rear seats

I did this and ran a second ground to the back

hmmm anyone got pics im not trying to ground it to the wrong bolt i know under the seat cusion the seat belt ones seem sturdy and solid but ppl are saying no

[poorfish88]

My amps were toward to rear of the trunk. I drilled a hole on the right side panel of the trunk.

And yes stay away from the back seat cause the gas tank is in the way. I wouldn't use

a seat bolt either.

I don't have any pics of it , cause I haven't had that car for a long time.

see to me the right side panel feels like thin ass sheet metal and not a solid thump from a solid location

[poorfish88]

True, you have to drill threw the sheet metal to get to the frame. Use a cromet and seal it up.

ya and what he is saying is to drill a hole in that thin ass sheet metal put in a rubber gromet and run your ground down to the frame use a wire brush or something to sand it to bare shiny metal then use a nut and bolt and bolt it to the frame.
