Lorenzo Lewis is the Team Captain for Wolfram Audio and has been representing the brand for over three years. He was drawn into car audio just over ten years ago by watching videos posted by Steve Meade. He currently competes in the USACI extreme class, with a personal best of 165.9dB @ 55hz in his Wolfram s10. He is planning a build that will be more oriented towards demoing, as he finds going to shows and handing out demos to be more fun than just strictly competing. The goal with his upcoming build is to have one of the windiest setups in the U.S. Lorenzo has multiple Wolfram builds including an s10, a trailblazer, and an econoline. Here I will give a breakdown of the Wolfram trailblazer and the upcoming Wolfram econoline.
