Where did you ground your amp to in the trunk? or is it a good idea to run a wire off the negative terminal on the battery as a ground?

I agree with krazyGs3. I've got mine mounted about 3-4 inches away from the subwoofer port. Sand down the paint and grab a pointed screw to drill through the metal with the ground wire terminal and you'll be fine.

Depending where you mount the amp a good place is on the frame rail on either side of the car in the back. It will be under the trunk "tray" and should be pretty obvious. It provides a thicker material than just sheet metal. Another place is all the way in the front of the trunk, near the back seat.
Just be careful that there isn't anything on the other side of where you drill and use a short screw with a large head so it makes good contact with the ground terminal. It also helps to use a larger diameter screw. Generally I would drill a small hole and then thread (using hand tools, not a drill etc...) a larger diameter screw until it was just past snug. Since the metal is relatively thin you have to be careful to not over tighten the bolt as it's easy to "strip" the sheet metal.
