I posted this question over in the Audio and Electronics forum and didn't get a response. I figured I would see if people might know here.

I have a computer that I am hardwiring in the car. I have a 4 gauge power wire running from the battery to the trunk. I am using a distribution block in order to run the correct gauge wire to the computer's power supply.

My question is ... is there a good grounding point which I could use in the trunk?
