Oh god... I hope you don't hit any bumps along the way. That photo makes the hair on the back of my neck stand up. Did you use blankets or anything to provide a little bit of cushion? It might just be me being overprotective, but when I moved from the mountains into town, I used all my towels, blankets, and sheets as make-shift cushions for all of my computer gear that I wasn't able to pack into boxes with Styrofoam peanuts.
Although, I suppose if you crank some loud music, those two subs I see might thump enough to create a cushion of air that would cause everything to kind of levitate and float harmlessly in your trunk all the way to your destination. Or maybe I'm watching too much SyFy channel.
