We could hook up the FM transmitter and use something like these at every table.

Lots of little speakers won't echo nearly as much as a few loud ones.
There's a table at the end of the drivers stand. Everyone should be setting there trucks there, not going back to the pits. (it also makes a good spot to check for chassis protector)
I haven't race off road in a few years, there are a lot of new people that I don't recognize. AKA, a lot of new marshals that don't know exactly what to do.
IMO the biggest 'marshal' issue I saw was them leaving before everyone was done... @spike, maybe waiting to announce that the qualifying was over until all cars had finished might help.
