I have a kicker zx1500.1 amp. I was upgrading the wires on the GND/+12v to 0 gauge when i accidently stripped the screw on the GND slot. Now my GND wire just sits in the slot rather than it being fastened down by the screw. The amp still works though. Any info on how I would replace or take out the screw. I tried using my drill with the crosstip,phillips tip and hex keys to try and take it out. I have attached a pic of the area I am talking about.
