Anybody know the best way in our cars to keep the box from sliding around? When I go around corners kind of quick, my box goes all over the place. I tried velcro and it wasnt strong enough. Any other ideas?

 

lol... my sub box weighs 100 lbs. I haven't needed to strap it down. A small L bracket would probably work, screw it into the sub box and into the floor/side.

 

Have you used the industrial strength velcro? You only need the rough side of the velcro. Stick that to the bottom of the box on all 4 sides, and put it down on the carpet where you want it to stay. I had 2 12's in the back of the Elantra for 4 years that never once moved unless I was the one to move them! You can buy the stuff by the ft at Wal-mart pretty cheap.
