After re-reading the article I posted above, it looks like my hypothesis is correct, and that there were/are four duplicate audio tapes for each of the ten sections of the spiel that is delivered throughout the ride- that explains why the audio is broadcast through four different channels; multiple pairs of vehicles would each be sticking their antenna fins near the same broadcast antennas at the same time, and using four different frequencies allows them to only hear each section of spiel with the appropriate timing.
This also means that no one section of spiel could be longer than the time it takes 8 doombuggies to travel past the point at which the spiel is triggered to begin playing- the ninth doombuggy (which would be listening for audio on the same frequency as doombuggies 1, 2, and 10 since consecutive pairs share one of the four frequencies) would be the start of a new cycle and the first tape would have to be done and ready for its "turn" to begin again.
