Made to Look Vintage, With Today's Bells and Whistles
The Custom Autosound USA-630 has the classic AM/FM look you'd see in DeSotos of the era. It also has CD changer control, a USB port for MP3 playback, a display for digital file information, a digital clock and much more.
Controls Worthy of the 21st Century
The USA-630's controls will make you forget you're in a car from the 1950s. It works with Custom Autosound's optional BluKit Bluetooth module, and it has a 4-way fader with left/right balance and bass and treble controls. Custom Autosound believes a vintage car shouldn't be stuck with a vintage radio that barely picks anything up. To capture the carefree days of the '50s and early '60s, your DeSoto needs music to match its looks.

Suggested order for a classic DeSoto
- Disconnect the vehicle battery before any wiring.
- Connect ground first, then constant (yellow) and ignition (red).
- Connect the antenna plug and the blue power-antenna lead if your car has a power antenna.
- Wire all four speakers, matching polarity.
- If using an amplifier, run RCA cables from the front/rear (and sub on USA-740/USA-850) pre-outs.
- Reconnect the battery and test radio, speakers, and charging system voltage.
Tech tips for classic DeSoto
- This radio is sold for the factory DeSoto opening used in classic models—do not cut a modern DIN rectangle if you want a stock look.
- A poor ground is the most common cause of whine or weak audio; scrape paint at the ground point and use a star washer.
- If AM reception is weak, check the antenna mast, cable continuity, and that the antenna plug is fully seated.
- Vintage Car Radio does not install radios. If you are not comfortable with 12V wiring, use a qualified installer.
