Box Adjustment Help

[Ndnkobra 0]

Hey guys, i need help and some kind of solution in securing my box in the trunk. its a premade JL audio box called a powerwedge, so the box is shaped...like a wedge in the back! The problem is the design of my trunk, since it has "bumps" on the sides, making it so the box wont fit directly straight in. Think of the box sitting on a slight decline, like a car going down a steep hill. The problem with this is that the box has already fallen over frontwards because a lot of the weight is sitting right in the front, and i dont want to damage the subwoofers (2 12" FI Q). I've already propped the front part of the box with 8 mini carpets, but i'm afraid that will only work as a temporary solution since i'm pretty sure the box will fall over again. If anyone else has an idea on how to tackle this problem, i'm open to all suggestions. Thanks! If you guys require pictures on how the trunk looks in order to suggest a solution, just let me know.

try some L brackets in the rear of the box

Velcro will help some.
