Rudy Costales told 12voltnews.com "I've followed the history of the Build Off since its inception. To be participating this year is an honor for our company." The Sounds Unique team selected a pearl white 2006 Toyota Avalon for the Build Off project. Castales said "The Avalon is a car many people can relate to and gives us a good amount of space to work some Stage 4 magic." Team Sounds Unique staff working on the Build Off 4.0 project include Rudy Costales, Efren Contreras, Shawn Stephens and Roman Caballero. Contreras gave 12voltnews.com a few insights into the project. "We will maintain a stock look up front and will jazz up the trunk area with an amp rack installation of lexan highlighted with neon accents."
