hey guys, i’m new here so i hope i’m doing this right. lol. i am trying to remove the factory subwoofer enclosure in my 2007 rubicon and i’m not sure what tools i need to use. i googled it and everything i found the guys had different kind of bolts so i’m confused. my bolts are pretty large and are 6-sided on the top like most bolts, but on top of that it has a large metal circle and i have no idea what tool i need to remove it. any ideas?
