More than a Company

We built this business from the ground up in order to serve classic car enthusiast looking for the best audio & someone who actually understands their cars. Big-box stores may have great sound systems, but most big-box employees know little about what stereos fit classic car dashboards, how to bring the best sound out of your system, or how to add a sound system while keeping things looking original. We strive to provide the best customer service in the business because we are people serving like-minded classic car loving people. Thanks for stopping by. We'd love to hear from you or if you can give us a chance to earn your business.
