USA-630 for the 1959-67 Buick Electra
The Custom Autosound USA-630 for the 1959-67 Buick Electra is fast becoming the top choice for vintage car owners, with features you'd expect only from the latest stereos. It changes the old idea that a classic radio can't offer modern conveniences. Stream music from a Bluetooth player with the optional BluKit, which also lets you take hands-free calls while the music mutes automatically, and tune in American or European stations at the press of a button.
Not Just by Driving the Buick Electra
...but by installing the perfect radio for its fine lines, powerful engine and smooth ride. With the right radio, you can enjoy great music, talk radio and more.
To match the style of your 1959-67 Buick Electra, let the Custom Autosound USA-630 deliver your audio. When you drive a top classic, second best won't do.
A Big Radio for a Big Car
That's the USA-630. It puts out 300 watts of power for the sound you want, and it plays MP3 and WMA files and controls up to 6 CDs, so you can enjoy concerts, audiobooks and more.
That's not all. You get 16 AM/FM presets (12 FM, 4 AM) on the RDS tuner, which displays song and artist names, plus a digital clock.
A power antenna lead helps bring in a clear signal so you don't miss a word or a note, and volume, bass and treble controls plus a digital EQ let you fine-tune your sound.
There are too many features to list. The USA-630 is simply a big radio that brings style to your classic Electra.
You Need a Big Radio
...because the Buick Electra is a big car with lots of space to fill, and the USA-630 fills it with top-quality sound.

- Connect the antenna plug and the blue power-antenna lead if your car has a power antenna.

Tech tips for 1959-1967 Electra
- This radio is sold for the factory Electra opening used in 1959-1967 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.
