That Jeep install brings back bad memories. Years ago I installed a system in a friend's jeep and he wanted to make it a little harder to steal, so we went to my grandfather's shop and I tack welded every bolt used to tie down the enclosure and amp.
Six months later, he calls me telling me that he is trading his jeep in and we need to pull the system. As fate would have it, my grandfather's one cutting torch was awaiting replacement parts and I had to cut all of those fricking bolts with a sawzall.
