I just got a 93 YJ and it came with a 10 in sub and 1000 watt amp. I love the sound aspect of it, but I'm concerned about securing it. Not do much it sliding around but more towards the anti-theft side of it. Being that it's a YJ and I can, and hopefully will soon be taking the hard top off and putting the soft top on or running no top, the sub and amp will be sitting virtually out in the open. Any ideas how I can secure it so no one can just walk up, yank the wires out and walk away with it?
