I have 2 Sub boxes in my trunk that aren't strapped down or anything, so if I ever get in a crash I'll have 2 big/heavy projectiles! How do you guys normally strap em down? I still need access to my spare tire or I would just get screw em right to the floor of the trunk.

I usually use L brackets. Screw them into the box and to the floor.

I've seen this one guy use L brackets in a way that makes them like hooks.

If you can just screw down some sort of handle and use the L brackets to grip on to them/it, it might work decent. After all, it's objective is to not move around, but not be permanent.

My box that I had in my van was really held in place by the terminal sets on the bottom. It was pretty heavy...

Use the L's, but screw them down first with the legs under the box. Then slide the box in and screw it to the box. The box hides the L's a bit better.

I use L brackets too.. how ever i have bolted.. yes bolted ( very large box ) my box to the frame of the car wit 4 1 " bolts. I know excessive :)
