A Guide to Choosing Car Receivers If you want to get a stereo for your car you should start with the deck or the head unit.

Choosing a receiver also involves look at plug-in sources, features, and the expandability of the rest of your car audio. After the audio is received from an audio source it then gets to the preamp. This is where all sound adjustments are made. This preamp sections includes controls which range from simple volume, balance, fader, source selection and tone adjustments, to sophisticated crossovers, equalizer and time corrections. It goes to the amplifier next. Before sounds are sent out to the speaker they are boosted from small audio signal coming from the preamp section into a larger audio signal.

These features include full color animated displays, customizable color schemes, touch screen monitors, and precision sound control like digital time correction. This is that which compensate for the uneven distances between left and right ear speakers and listeners’ ears which is the processing circuit found in some receivers. It delays signal from the closest speaker, so that all the sound arrives at your off-center listening position at the same time to make one get a more accurate, lifelike stereo image. Another advanced feature is the parametric equalization that allows you to adjust the volume level of a frequency, or range of frequencies, within an audio signal.

There are USB connections, and audio/video outputs that will allow you to expand your system by connecting portable music players, rear seat screens, external amplifiers, and powered subwoofers. You should also consider putting security features in your car stereo like detachable face plates and security codes so that they are protected from thieves.
