sub box help

[and1]

I have a box w/ 2 10's in my trunk. How can I put it in there so nobody can steal it from me. What material will i need? I have a 1990 Chevrolet Corsica.

L brackets, bolts, drill

Yep.
And you can install them stealth if you desire, so it appears that there's nothing to steal

A trick I did once in a friends mustang hatch was drill holes in the bottom of the box and put a set of carriage bolts in and bolted it where we removed some tie downs. You might be able to use a threaded rod and attach it to the floor.
