It is important for cars today since it is this part where you will directly interact with from behind the wheel. This is also often called the receiver 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.

When audio is received from an audio source, it gets to the preamp. Sound adjustments are all made here. The preamp section includes controls ranging from simple volume, balance, fader, source selection, and tone adjustments to sophisticated crossovers, equalizer and time corrections.

Full color animated displays, customizable color schemes, touch screen monitors, and precision sound control like digital time correction are all included in the advanced features that are found in new stereos. This processing circuit found in some receivers compensate for the uneven distances between left and right car speakers and listeners’ ears. 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. There is another advanced feature which is the parametric equalization which allows you to adjust the volume level of a frequency or range of frequencies within an audio signal.

The expandability or auxiliary inputs to a receiver is another aspect that you ought to look for also. This includes 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.

One last important thing to remind you is security -features like detachable face plates and security codes help protect your investment from theft.
