Jefferson Bryant grew up on cars. His father taught him how to turn a wrench on their 1987 Chevy Suburban, among other cars they owned. At 17, Jefferson began working on car audio systems and fell in love with sound. So much so, that his first car had a booming sound system before it was drivable.

After high school, Jefferson earned a Business Marketing degree from Oklahoma State University. He’s also earned certifications from the Mobile Electronics Certification Program, including MECP Certified Product Specialist and MECP Certified Installer.

When Jefferson was first getting started, Boyd Coddington helped open a lot of doors. Since then, Jefferson has gained extensive experience with automotive audio, having worked at Cartunes and Audio Midwest, running sales and custom installations. At Rockford Fosgate, Jefferson was a Plastic Design Specialist, where he designed vehicle-specific car audio components for the manufacture, like kick panels and subwoofer enclosures. During those early days in car audio, Jefferson started his own Bryant Media company, producing how-to articles and videos for the automotive industry. He also worked for PowerBlock TV, writing articles and transcribing TV shows, as well as SpeedDirect, handling tech support for Corvette and Camaro suspension and steering products.

Jefferson’s book, “LS Swaps: How to Swap GM LS Engines into Almost Anything,” has been on best seller lists for 13 years straight. Three of his builds have been featured at SEMA 2013, 2014 and 2015. He won Top 5 MOPAR at SEMA 2013 and Top 10 Hot Rods at SEMA 2014. In 2001, Jefferson made 5th place at the IASCA SPL Regional Championship. In 2002, he won dB Drag Racing World's Loudest True Convertible, in addition to multiple car audio competition 1st and 2nd place wins.

Over the years, Jefferson has gained a high level of skill in car audio, electrical wiring, fabrication, engine swaps, sheet metal fabrication, chassis and suspension, metal and plastic casting, painting and plumbing and hardline fabrication. He is a member of the Texas Auto Writers Association and the Midwest Automotive Media Association.
