Spencer Marshall

Spencer Marshall became interested in mobile audio at the age of 14 when he first put a radio and speakers on his four-wheeler. Spencer does demo frequently and his best score to date is a 154.9 dB. The inspiration for his current build is to continue to have fun. He loves to help educate others as well as to learn new things himself. “You never know everything and every day is a new learning experience.”
