Where is a good grounding point in the trunk? I have a sub installed, but the ground isn't too good.

Just make sure you sand some of the paint away. You'll get a better ground that way.

actually you can put a good ground anywhere in your trunk, find the best location, drill a hole in a area you can get to the back side. sand hole down to bare metal spray are with WD-40 to prevent rust, stick a flat washer and bolt thru the back side, put a flat washer, spring washer, and check nut. securely tighten. add your ground lugs for you amp put another flat washer, spring washer and final nut and your good to go.

something along the lines of this

for putting in a amp and sub i'd highly suggest making them have their own dedicated grounds
