What is a car stereo?

As explained above a car stereo is one of the numerous family members of an embroidered car audio system. It includes in its components the radio, (AM or FM) radio, multi-tracks tape players, cassette players, record players, CD players, DVD players, Blu-ray players, navigation systems, Bluetooth, telephone integration, smartphone controller (that can now be operated on steering wheels) as well as CarPlay and Android Auto(that are now being controlled with just voice commands) all these arranged according to emerging technologies in the automobile world.

 

 

How do car stereo work?

To better understand how car stereo (or broadly speaking car audio) works is to first get knowledge of the basic components that create music in your vehicle. These basic components are the head unit, the amplifier and the speakers.

Head Unit

With the constraint of space, automakers combined as many as possible components such as obtained in normal household audio system like a radio tuner, CD player, preamp, amplifier etc to come up with just one device, the head unit. This device performs various functions but the most important two are to control all the sources of audio in the vehicle as well as controlling the overall system volume.

Way back, the only audio source in any car was the AM radio followed by FM and tape format such as 8-track cassette then CD and DVD players and satellite radio connections through subscription service and so on. Now technology has improved the capacities of head units to include playing music via the Bluetooth streamed without any wire connection from a compatible mobile phone.

To enhance good sound production to your taste, head units now include basic tone control such as bass and treble and signal processing device. Depending on the environmental and inside noise in and around your car, this device automatically adjusts the volume of the sound in your car. We now have some OEM audio systems that come with subwoofers and its various level controls.

 

The Speakers

The electrical signals supplied by the head unit are being modified and converted into mechanical energy by the speakers to move its cone back and forth to create audible sound which is the vibrations in the air that we hear in frequency ranging from about 2Hz(extremely low bass) to about 20,000Hz(on the very high notes).

A full range speaker is designed basically for automobiles to cover the entire frequency range with bass response nearly non existing and duller higher frequencies.

To enjoy a balanced sound production therefore, getting assorted speakers specifically built to reproduce smaller range of sound is recommended. This brought about woofers and subwoofers designed to reproduce only low-frequency bass sounds. Sometimes and in many car sound system, two speakers of different sizes are framed together to create a two-way speaker system.

 

 

The Amplifier

For effective power supply to drive the head unit as well as to receive accurate audio signal strong enough to move the speakers and create audible sound there is the need to get an amplifier to support both the speaker and the stereo system. This is being handled by the preamp and power amplifier jointly.

The preamp is built inside the head unit to prepare data taken from the radio, the CD or DVD player or any other audio source for the power amplifier. This is done by boosting the audio signal to a compatible level with the amplifier’s power to resist noise radiating from other electronics in the car. This preamp’s low- level signal is then boosted by the power amplifier to move the speakers and produce better sound.

Although some head units come with small in-built low-power amplifier to drive smaller speakers, it advisable to get a separate power amplifier for speakers mounted far away from the head unit which will boost the power supply as better sound from the speakers requires more power to push the cone.

 

 

Subwoofers

Other member of the car audio system family is the sub-woofer which is built specifically to produce heavy sound. To balance audibility and counter external obstructive sound, some sound-deadening materials are sometimes fastened to either the boot area or the car doors to dampen excessive car panel vibrations.

How do I get the code for my car stereo?

To get your car stereo code, follow our advice as stated under if you can patiently do it yourself or follow any of these listed steps:

  • Check your owner’s manual to find out
  • Visit the manufacturer’s website
  • Visit your local auto dealer or
  • Contact a local automobile car audio installation center

Some car stereos are uniquely coded by manufacturers to deter stealing. Thus, removing or attempt to transfer such stereo from the car renders it useless and unusable except one enters the specific code that comes with it which are usually attached in serial number. Sometimes also, when your car’s battery is disconnected the stereo “locks” off which means you will have to re-enter the code to use the stereo again. Here are few tips for you to troubleshoot.

Through your car’s owner manual or the manual that comes with the car stereo (if you bought it separately thereafter), you must have been given a code. If lost, revert back to the owner’s manual and if you can’t lay your hands on it anymore, contact your car’s manufacturer and provide them with the serial number to your car stereo. They should be able to provide the code.

You may also turn on your car and the radio. Luckily, the word “code” or “locked” may appear. If it does, enter your serial code using the numbered buttons on your car stereo or touch screen.

Some stereos are configured that the number “1” is to be repeatedly pushed to reach your desired number, do this till you are sure you have entered the correct code which will automatically unlock your stereo.

If you make mistakes and your car stereo will no longer accept your input, turn off your car engine and wait for about 15 minutes. Turn on your ignition again to repeat the above steps. If it will not yield, then contact your auto maker.
