The 1959-63 Buick Invicta is a true classic, known for its bold styling and powerful performance.

For those who prefer external media, the unit includes USB and auxiliary inputs, making it easy to connect MP3 players or flash drives. Additionally, it is CD changer compatible, allowing you to integrate a separate CD player for even more music options.
With 300 watts of power (75 watts per channel), the USA-850 delivers exceptional sound quality, ensuring that your music is heard loud and clear. The four-channel RCA pre-outs and subwoofer output give you the flexibility to expand your audio system with additional amplifiers and speakers.
Designed to fit perfectly into the dash of your 1959-63 Buick Invicta, the USA-850 maintains the classic look while providing a modern, high-performance audio experience.

Tech tips for 1959-1963 Buick Invicta
- This radio is sold for the factory Buick Invicta opening used in 1959-1963 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.
