OK, so Liquid Nails doesn't work, now what?
I wanted to attach 4 bolts to the bare hatch floor, in order to anchor a wooden board to mount the amp and crossovers. After 2 days, the bolts just popped off with light finger pressure, the glue still feels kinda rubbery. Maybe due to the cold temp around here? 40s at night, car is parked indoor, so maybe 50s inside the garage. What can I use to firmly glue the bolts? Thanks,

Rough the surfacees up with some 80 grit sand paper and use some Loctite 5 Minute Epoxy or better yet some Loctite Epoxy Plastic Bonder. Avoid the one minute or instant stuff because it is not as strong. You can get the stuff at Home Depot type places.

Yup ... I glued a board on the wall behind my passenger seat for my amp (the board sets vertically). The 5 minute epoxy holds perfectly.
Before glueing on the board, I drilled 4 holes in the board and inserted 4 threaded 'collars'. These collars will accept the threaded screws that will attach the amp to the board.

Looking at your photos, you might be going about this the wrong way ... the glue may not be strong enough to hold just those bolts to the floor.
Glue the back of the board directly to the floor, then screw the amp down to the board. That will give the epoxy a larger area to hold the board, and the bond won't fail.
I wish I had taken a photo of the threaded collars that I inserted into the board before glueing the board down .. but, unfortunatly I didn't. Anyway, I got the collars at Lowes (in the section that has all the stainless nuts and bolts and various fasteners).
The collars will push into the back of the board.

I'm planning to use elevator-bolts (they have a big flat 1" head) and lots of premium epoxy, to hold my digital processor and maybe an amp behind the pass. seat, less thickness than using the board ...

icanski: thanks for the tip. I thought Liquid Nails would be good enough. Also should've roughened up the surface too.
Turbo: I don't want to glue the board directly to the floor. My plan is to have the bolts stick up through the carpet, and the board will be secured to those bolts.
Thrash: I went looking for them "elevator" bolts, guy at Lowes said they didn'tcarry those, so I found something else similar. Head diameter is not 1", that's why I got 4 of 'em.

usually when someone sits in the seat and have any recline to the seat back there will be quite a bit more room at the bottom. the backs of the seats usually rest on the top part of the area where that amp will be mounted.
also its a lot harder to see the amps if they are located lower on that wall.
