I switched from a Bestop Instatrunk to the Olympic looking for more room to hide electronics. I installed two rails sitting on the wheel wells to suspend my electronics above ground and out of the way. With a subwoofer, voltage adapter, distrobution block and a 12v plug I still had more room than in my Bestop. Plus it covered the wires that used to snake around the seat belt bases in the back. It also left me with two little cubby holes to stash tow rope and gloves or little what nots. I was impressed with the thickness of the metal and the ease of install. The finish was texured rubicon black powdercoating at no additional cost which was really nice looking and tough.
It does make it a bit tough to reach the rear seat release on older TJ's that don't have the release high in the rear of the seat. I cut a hole in the box to eliminate that problem.
