Getting the HK amp out of the rear fender well. I have been trying to get the amp out of this location. There are 2 mounting screws that are very easy to get to but the mounting bracket is still secure. Any ideas on how to get to the last screw. One thread said he just needed a screw driver with a 12 inch shaft. Have that but where is the screw?

Help before I shoot this darn HK system that simply just stopped providing sound while driving along in my 2004 Mini S

 

You can access it through the home wear the rear light is. Just pop out the light/lens.
