So i was driving home from work...when i could hear my subs sliding torwards the rear of my hatch!

This angers me cause it sounds like sh!t. So i had this brilliant idea

!
I WILL BUILD MY OWN CUSTOM BOX!
So i have started to gather my materials...that i think i am going to need!
1. Wood
2. Plexy Glass
3. Nails and screws
4. Glue
5. PAINT!
6. Hinges
7. Metal Chain
8. Sand paper
9. Wood Cutter!
10. bandades (i am accident prone)
Anyone got any good ideas as to what i should remember not to do, or what to do!?
I am thinking outside the box, im talking this thing is going to be nutty looking! nothin like you seen before!
"MTV PIMP MY RIDE STYLE!" not so ghetto lookin though!
All the help is appreciated!
Thanks,
DJMC
