i have a box design! what do you all think of having a 12 inch subwoofer with an amp, and a storage area all in one? the storage area will not be covered, but i can incorporate it in the box, and when the seat is down it will hold everything in place. all sides will be enclosed, and a locking lid could be added upon request. also with this current plan, you can fit 2 12 inwoofers and still have some storage. approximately the 1/3 section. input quick, i am getting ready to lay glass in about 1 hour.
