From 1963 through 1967 Corvette radios were quite different. Most original radios were AM only with no cassette players or FM tuning available. During the late 1970s cassette tapes were introduced. At that time CAM developed a technique to modify AM-FM/cassette players to fit into the original radio openings of these classic Corvettes. Carl used his own 1963 Corvette coupe to prototype his initial offerings. The initial concept of fitting modern radios into current classic vehicle was readily expanded into the car/year group applications-1955-1957 Chevy and 1964-1973 Mustangs among them. This expansion of product lines involved many hours of research and development. Part of the process involved locating the various classic vehicles, acquiring the original dashboards, and developing a minimum of two speakers required for stereo effect. Since most vehicles from the 1940s to 1980s were originally equipped with a single front speaker, CAM developed a dual front speaker assembly that fit that area without modification to the vehicle. This was accomplished for all vehicle applications offered, providing a complete modern audio system for their customers. The mid 1980's brought considerable growth for CAM. They proceeded to design and manufacture their own brand of radios and speakers. CAM's designs and specification from the factories allowed for more classic design (i.e. chrome radios) and better quality components than offered in current off the shelf units available from local wholesalers. With the advent of compact disc systems during the 1990s, CAM developed several radios that actually controlled remote CD players and still fit the original radio openings. Since 1977, Custom Autosound Mfg. remains the originator and innovator of audio products for classic cars, trucks and streetrods. Many competitors and imitators have followed in their footsteps with similar products, but only Custom Autosound offers over 400 different radio applications for the year, make, and model of your vintage vehicle; ready to install. Everything you need in one box and nothing to assemble. In addition to the custom radios, they offer a multitude of upgrade/custom fit speakers and kick panel speakers. Custom Autosound Mfg. is a regular exhibitor at SEMA and is licensed by Ford and GM to use their trademarks and logos.

The Custom Autosound Story - Pioneering Classic Car Audio Since 1977

Custom Autosound Manufacturing Inc. began in founder Carl Sprague's Fullerton, California garage with a singular vision addressing a real need. As a Corvette enthusiast, Carl recognized that classic car owners lacked modern stereo options that properly fit original radio openings. His 1963 Corvette coupe became the testbed for developing techniques to adapt contemporary AM/FM cassette players into vintage dash configurations.

The initial Corvette application quickly expanded to encompass iconic vehicle groups including 1955-1957 Chevys and 1964-1973 Mustangs. This expansion required extensive research, development, and hands-on testing with actual classic vehicles. Custom Autosound acquired original dashboards for precise measurements and engineered dual front speaker assemblies that install in factory locations without vehicle modifications.

Manufacturing Excellence and Innovation

By the mid-1980s, Custom Autosound had achieved substantial growth and began manufacturing their own branded radios and speakers. This vertical integration allowed Custom Autosound to specify chrome finishes, premium components, and classic styling unavailable from conventional wholesale suppliers. When compact disc technology emerged in the 1990s, Custom Autosound developed innovative radios with remote CD player control that maintained factory radio opening compatibility.

Today, Custom Autosound offers over 400 different radio applications engineered for specific year, make, and model combinations. Each system arrives ready to install with everything included in one box and nothing requiring assembly. The company maintains licensing agreements with Ford and General Motors to use authentic trademarks and logos, and regularly exhibits at SEMA showcasing new product innovations.

Complete Audio Solutions for Every Classic Chevy

Custom Autosound engineers their products around the unique requirements of classic vehicles. Most cars from the 1940s through 1980s originally featured single front speakers, creating significant audio quality limitations. Custom Autosound addressed this challenge by developing dual front speaker assemblies that fit original mounting locations without cutting, drilling, or permanent modifications.

Their kick panel speaker systems provide additional sound staging for vehicles with air conditioning or specific dash configurations. These custom-molded panels include integrated 80-watt or 130-watt speakers designed to complement the acoustic properties of vintage interiors. Rear speaker packages with grilles and undercover speakers deliver full-cabin audio coverage while maintaining your vehicle's stock appearance.

Custom Autosound Radio Features and Technology

Custom Autosound radios combine authentic vintage styling with features modern drivers expect. The USA-630 and USA-740 series offer AM/FM stereo tuning with digital displays hidden behind classic knobs and bezels. Bluetooth adapter kits transform these radios into wireless streaming platforms, connecting smartphones for music, navigation prompts, and hands-free calling without visible modifications to the dashboard.

The slide-bar radio design replicates the iconic push-button tuning mechanisms found in 1950s and early 1960s vehicles. These radios incorporate modern circuitry behind period-correct faceplates, delivering superior sound quality while preserving concours-level authenticity. Single CD players mount remotely under seats or in trunks, controlled directly from Custom Autosound head units.

Model-Specific Engineering for Perfect Fit

Custom Autosound manufactures radios for precise vehicle applications, ensuring factory mounting bolt patterns, connector locations, and bezel dimensions match your classic Chevy perfectly.

Why Choose Custom Autosound Over Generic Solutions

While aftermarket electronics retailers offer universal head units, these products rarely integrate seamlessly with classic vehicles. Custom Autosound's specialized approach delivers authentic appearance, proper fitment, and reliability specifically engineered for vintage cars and trucks. Their radios accommodate the curved dashboards, limited mounting depth, and unique bezel shapes found in classic Chevys that generic units cannot address.

Custom Autosound products also consider the electrical characteristics of older vehicles, including positive-ground systems on some applications and generator-based charging. This attention to classic car requirements prevents installation problems and ensures long-term durability under conditions that might damage conventional car stereos designed for modern vehicles.
