listen to what AERO D said... you should use self tapping screws,, estimate 50 cents each and drill those into the frame of ur trunk... the frame will have paint on it so be sure to take some sand paper and just clear the paint for best conectivity..
you should never run your ground to your battery, to your amp.. it should be as short as possible, and attached to bare metal , like the frame. and if you have an issue with one, you could very quickly have an issue with both.. I REALLY hope you fused at least the power wire!!!!!
Make sure the edges of the hole aren't sharp or rough, to prevent the wire insulation being damaged. Usually, the ground wire on the amp is mounted to nearby metal instead of running a line all the way to the engine. Then, you can beef up the wire from the battery to frame in the engine compartment if necessary.
