Removable sub box?

[67rally]

I mounted the subwoofers to the box and mounted the box to the trunk. I wanted to be able to easily remove the box incase I ever AutoX it. I would just need to unbolt four 1/4" bolts from the sides and slip it out. Finding a location for the brackets I fabricated turned out to be a challenge. The rear frame rails run right below Everywhere I wanted to attach them. The carpet on them isn't a perfect match but eventually I will build some panels to carry the ends of the box out to the quarters.



Brackets:




Carpeted and bolted down:




This is where I left off. I still need to add some grilles to protect the subs:
