If you're restoring a classic car and need a radio that looks period-correct but works with today’s audio demands, the Custom Autosound USA-740 and USA-630 are two of the most popular choices. They share a lot in common—solid in-dash vintage looks, plug-and-play installation, and modern power—but each brings its own strengths. Here’s a breakdown to help you pick the right one.
- What they share: Both the USA-740 and the USA-630 deliver 300 watts peak power (Custom Autosound specs) and are built to fit factory dash openings—no cutting or trimming needed. They come with USB thumb drive playback, auxiliary inputs, digital AM/FM tuning, and multiple RCA pre-outs for amplifiers and subwoofers.
They’re also engineered for easy installation—pre-assembled, dash-specific bezels, and wiring harness support make them suitable for DIY use or professional installs. - USA-740: Feature-Rich Flagship: The USA-740 is Custom Autosound’s top-end classic radio model. Key advantages:
- Built-in Bluetooth and an included remote microphone for hands-free calling and wireless music streaming.
- AM/FM RDS tuner with 25 presets (15 FM / 10 AM) and on-screen station or song info.
- USB playback for MP3/WMA/FLAC/WAV formats plus front mini-jack and rear RCA auxiliary inputs for flexible audio sources.
- Four high-voltage RCA pre-outs AND a dedicated subwoofer line-out with level control and crossover options.
- Seven different LCD color choices to match your instrument cluster, and full DSP EQ with fader control.
If you want maximum modern connectivity and value Bluetooth out of the box, the USA-740 is the go-to.
- USA-630: Solid Performer with Lower Key Cost
The USA-630 is a simpler but very capable option.
Highlights include:
1. AM/FM stereo, USB thumb drive playback, and optional Bluetooth via the separate BluKit add-on.
