When I finally got around to buying a CB radio for my truck I was faced with the problem of where to mount it. There are not a lot of options. I've seen them mounted up on the ceiling, under the seat, or the usual place in front of the center seat on one of those sheet metal brackets. The problem with any of those is that the radio is always out and visible. I wanted it in the truck, hooked up all the time but I did not want to see it. I wanted it accessable and easy to bring into service but also easy to store away. This is what I came up with.
I had to remove my under-seat rear cupholders but I never used them anyway. I made an inverted U out of 1/2" baltic birch plywood with a groove milled into the down-facing legs to accept a 3/4" by 1/4" aluminum bar that I mounted to the radio using existing screws and the main mounting point. The plywood U is mounted to the center seat supports with the same method used for the cupholders, which is just a piece of sheetmetal sandwiched between the seat and the four support points with the bolts going through them so it floats above the carpet.
The radio hinges forward and slides under the seat when not in use but can be slid out and hinged up so that it rests against the center seat when I want to use it. It is hinged on two 1/4" flathead screws with a Nylok nut so that I can adjust the tension on the hinge.
The radio is not visible from outside the truck but in 2 seconds I can slide it forward and up into position, the antenna and power are always connected, the cables having a large loop so that there is not bending stress.
