What You Know "car stereo"

What you know car stereo?
A car stereo is the centerpiece of any car audio system. Also known as a radio, receiver, or head unit, today's car stereo performs a variety of complex functions. To understand these functions, it's helpful to think of a car stereo as having 3 different sections:

1. Source - This is the part that "plays" the music. Sources may include a standard AM/FM tuner, CD player, MP3/WMA/AAC decoding, satellite radio, iPod® connections, USB inputs, DVD player, or even cassette.
2. Preamp - This is where all sound adjustments are made. The preamp section includes controls ranging from simple volume, balance, fader, source selection, and tone adjustments to sophisticated crossovers, equalizers, and time correction.
3. Amplifier - The amplifier section boosts the small (low-voltage) audio signal coming from the pre-amp section into a larger (high-voltage) audio signal that's sent out to the speakers.
