Product Description
For Your Classic 1966-67 El Camino
Chevy's classic 1966-67 El Camino may be part car and part pickup, but it still needs the right radio to fill its cab with great music. That radio is the top-of-the-line Custom Autosound USA-230.
Only the best will do when you want to rock your way down the road. Or if you prefer softer music, the USA-230 will astound you there too.
Great Radio, Great Sound
The USA-230's 200 watts give you the power to hear your music the way you want, filling every corner of the cab.
A power antenna lead helps your 16 presets (12 FM, 4 AM) come in loud and clear, and the electronic tuner dials them in with little static or interference.
You also get 4-channel RCA pre-outs, an aux jack and a 4-way fader to fine-tune your music. And when it gets late, check the digital clock so you make curfew.
The Right Radio Rules
That's the key to great music in your classic 1966-67 El Camino. The USA-230 is the right radio for this Chevy classic, with results that are second to none.
Choose the right radio for the right results and have fun listening to your music.

Suggested order for a 1966-67 El Camino

- 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.

Tech tips for 1966-67 El Camino
- This radio is sold for the factory El Camino opening used in 1966-67 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.
