Looking On The Bright Side of Audio

A Guide to Car Audio

The deck or the head unit should be the point to start with when thinking about getting a car stereo. It is important for cars today since it is this part where you will directly interact with from behind the wheel. This is what is called the receiver of the head unit. When you choose a receiver, you are also looking at plug-in sources, features, and the expandability of the rest of your car audio system.

The audio gets to the preamp after it is received from an audio source. 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, equalizer and time corrections.

The next place where it goes is the amplifier. This section boosts that small (low-voltage) audio signal coming from the preamp section into a larger (high-voltage) audio signal that is sent out to the speakers.

Advanced capabilities from MPs/WMA/AAC playback, iPod or Android support, Satellite Radio, HD radio reception, DVD playback, Bluetooth connectivity, GPS navigation or Pandora support are just some of the things offered by aftermarket stereo. They also give cleaner, richer, more detailed sound.

Another reason in choosing a receiver are those other advanced features found in new stereos. 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 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. In order to make one get a more accurate, lifelike stereo image, it delays signal from the closest speak so that all the sound arrives at your off-center listening position at the same time. In order to adjust the volume level of a frequency, or range of frequencies with an audio signal, there is another feature called the parametric equalization.

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

Security is another important thing to consider which you can get from features like detachable face plates and security codes to help protect your investment from theft.
