Not unlike many, I've been thinking out loud for years (just ask my girlfriend) about removing the rear seats and building a storage trunk for the Jeep. No more keeping my socket sets under the seats and my wrenches behind the bench alongside my crappy speakers and old blankets. The Jeep deserved more. I deserved more.
Here I will chronicle the building of a versatile trunk. It will accomplish a few things:
1) have space for tools, fluids, recovery equipment, and other things
2) have a self contained speaker system
3) incorporate electronics/amplifiers
4) seal up, lock, be water resistant
The box will only occupy the amount of space that the rear area accommodates, and will have a hinged top to allow access to the entire box at once. I debated drawers, multiple compartments, but the easiest way for this to be versatile is for it to be all accessible with one fell swoop. This will be done via 2 hydraulic pistons on each side to hoist the top up once the lock and latch are undone.
I don't have any diagrams of what I'll be doing, but envision a large area (technically 35"x34.5") that is largely open. It will be broken technically into 3 sections, one being the storage area, 2 being the subwoofer enclosure (sealed, not ported) and 3 being the amplifier storage. The hinged lid will only cover area 1. The other 2 will be boxed in.
So I went to Home Depot and picked up two 4'x8' sheets of Poplar plywood. It is gorgeous wood, and should be perfect for the application. I also grabbed some 1"x1.5" strapping to brace the insides once assembled.
So here's what I got done on day 1 with some interruptions.
35" long (tailgate to seats)
34.5" wide (between wheel wells)
12.75" tall (floor to top of wheel wells)
Note: the front area that goes against the seats is cut at an angle to allow the seats to slide all the way back on their rails and still recline to a comfortable position.
