When it comes to upgrading the stereo system in a classic car, two of the most recognized names are Custom Autosound and Retrosound. Both companies specialize in radios designed to fit vintage vehicles without cutting or modifying the dash. While they share the same mission, each brand takes a slightly different approach. Here’s a closer look at Custom Autosound vs. Retrosound, so you can decide which option is best for your classic ride.

Authentic Appearance

Custom Autosound has built its reputation on creating radios that replicate the original look and feel of factory units. Their products are designed for specific makes and models, so the knobs, bezels, and faceplates blend seamlessly into the dash. Retrosound, on the other hand, uses a modular “infinite adjustability” system, which makes their radios adaptable to many vehicles. While this gives flexibility, some enthusiasts feel that Custom Autosound achieves a more period-correct appearance.

Features and Technology

Both brands offer modern features hidden inside vintage designs. Expect to see Bluetooth connectivity, USB ports, auxiliary inputs, and AM/FM digital tuners in both product lines. Where they differ is in flexibility. Retrosound often packs more expanded audio controls and compatibility with aftermarket speakers and amplifiers. Custom Autosound radios, meanwhile, are tailored to specific cars, which simplifies installation and ensures the right fit without extra adjustments.

Installation

For classic car owners who value plug-and-play simplicity, Custom Autosound is often the easier choice. Since their radios are designed to match particular vehicles, installation typically requires less adjustment. Retrosound’s adaptability means more effort during setup—especially in aligning knobs and faceplates—but it also provides versatility for rare or unusual dashboards.

Sound Quality

Both brands deliver solid performance, though reviews often note that Retrosound offers slightly more advanced audio customization. However, Custom Autosound’s radios are praised for delivering reliable sound that matches the needs of most restorers, particularly when paired with their kick panels, speakers, and subwoofer options.

Value and Purpose

If your goal is authenticity and originality, Custom Autosound usually comes out ahead. If you want maximum adjustability and features across multiple vehicles, Retrosound may be the better choice. Both brands meet modern safety and reliability standards, so the final decision often comes down to whether you prioritize factory-correct styling or customization flexibility.

Conclusion

At the end of the day, both Custom Autosound and Retrosound provide excellent solutions for classic car enthusiasts who want modern sound without sacrificing vintage charm. Custom Autosound shines in model-specific authenticity and ease of installation, while Retrosound excels in adaptability and feature-rich designs. Either way, your classic car will look period-correct and sound incredible—exactly what every enthusiast wants.
