Mike S. from Cape Coral, FL, wanted to add premium sound to his Backdraft Racing Roadster, which replicates the iconic looks of the 1965 Shelby Cobra. He tricked out his car with a 12" Polk Audio DXi subwoofer, some Polk Audio component speakers, and a pair of Polk Audio amplifiers.
Elliot C's sweet low-mileage 1990 Mazda Miata needed new speakers, so he upgraded the whole system with a new receiver with some handy extra features, plus a compact powered subwoofer for added punch.
Factory speakers tend to be made from materials that can't handle the extreme conditions found in a car. Over time, they deteriorate, distorting high notes, strangling bass, and robbing the sound of power. Aftermarket speakers are built to deliver sound as pure as the dawn after a stormy night.
