Gotta question for you guys, Im trying to find out if I should do another spot for my ground wire coming from my battery. My main battery is in the trunk and it has some metal piece attached to it where the stock ground was located and unpainted. Not to long ago I scraped the paint of the metal and redid the ground with bigger wires. In the pictures below I will show you were I drilled a hole on the bottom of the trunk floor to make a new ground spot but the metal there is very thing (if you push on it it waves a little). Is there a level of thickness the metal needs to be to be a good ground. If not then the last pictures is a whole I will run the wire through to the frame of the vehicle, I dont want to have a wire under/outside the car but if I have to I will. Thanks guys and on to the pictures:
