* AM/FM Radio: This was the core component. It likely had a cassette player as well. CD players were becoming more common but weren't standard equipment on base models of that era.
* Speakers: Usually four speakers; two in the front doors and two in the rear deck. These were likely smaller, less powerful speakers than what's found in modern cars. The sound quality was quite modest.
* Amplifier: A basic built-in amplifier within the radio head unit itself was common. Separate, external amplifiers were rarely found in factory installations at this time.
There were likely options available at the time of purchase that could upgrade the audio system. For example, some Skylarks may have been equipped with a premium sound system featuring slightly better speakers and possibly a more powerful amplifier, or a factory-installed CD player. However, the basic components outlined above were standard.
