Looking for a radio for his own car, Carl Sprague stumbled upon a great business idea: making custom radios for older cars that don’t have many options available. Since that day, and more than 38 years ago, Custom Autosound now offers radios for hundreds of applications created to fill the dashboards of cars that once only had an old knob-style radio.

As the designs and applications grew, so did the technology. Before long the modern audio gadgetry, like USB and iPod jacks, became a part of its repertoire. While these new radios provide stereo options that go far beyond the original radio that filled the hole, one feature that many love is that the radio still looks like a factory AM radio, giving it a very stealthy appeal.

Arriving fresh to SEMA this year, a new Bluetooth-ready radio was introduced. It will cover dozens of applications upon its release in the coming months, from the 1940s through 1990s for several manufacturers, including GM, Ford, and Mopar. Like many of its other radios, the new Bluetooth radio can be switched through seven different colors on the dial.

Of course, one of its popular radio designs to date has been the highly successful slidebar radio. With the look of an AM radio, it has a bar that slides the faux display down to reveal the digital readout of the radio. Each radio can be connected to an amplifier, or the internal amp can provide enough power to give your ride some great cruising tunes.
