A car stereo is an electronic device installed in vehicles that plays audio from various sources, such as radio, CDs, or digital music files. It typically includes a receiver, speakers, and sometimes an amplifier, allowing drivers and passengers to enjoy music, news, and other audio entertainment while on the road. Modern car stereos often come with additional features like Bluetooth connectivity, USB ports, and touchscreen displays. These enhancements enable users to connect their smartphones or other devices, making it easier to access playlists and streaming services, enhancing the overall driving experience.
