Inferno Audio, Woonsocket

Hundreds of cars roll off the production line each day, with little to distinguish one sedan or SUV from another. That’s where the auto enthusiasts at Inferno Audio come in. They outfit vehicles with all the tricks and toys necessary to help them stand out—a list that includes custom subwoofers, window tints, and remote starters that keep interior temperatures comfortable throughout the year. They back up every job with a lifetime warranty and make themselves available for questions via text message or live chat in case an ejector seat fails to jettison an irritating passenger.
