trying to find a competitions name. please help

HI I am trying to find information on a competition that has all the loud pro audio speakers and the microphone is placed on a stand behind the car to measure how loud it is. I have been searching everywhere but must be looking over it. there are pictures of utes on you tube with hundreds of speakers in the tray and a mic behind. What is the name of this competition.
