the cab or part of the shell [8]). Of course, the cab needs to be
fully glassed and sealed for the enclosure to be effective.
Figure 8 shows one such installation in an Atlas Alco RS-1. Here
the shell was most of the enclosure. The speaker is caulked into
the shell and has a bit of styrene, not visible in [8], between
the top of the shell and the front of the speaker to complete
the enclosure. The speaker wires (purple) and rear LED (black)
pass through notches in the styrene wall and are caulked in
place. Glue the speaker and the styrene with caulk. That way,
they can be removed if necessary, unlike what happens with
styrene cement.
I don’t recommend this design without a LED light. My luck
would be that an incandescent bulb would burn out as soon as

the truck.
