Electronic Components for Car Audio

Understanding the electronic components for a vehicle audio is important for those who want to modify their car. By learning more about the workings of the components, an owner can install whatever system they prefer without worrying about problems in the overall equipment. Following are some of the most basic electronic components for a car audio.


As the name suggests, a resistor “resists” the flow of electricity in the circuit, thereby acting as a protector from any dangers resulting from the flow of power.


Most often used in security systems for cars, a relay is a type of switch that is usually used in protecting a unit from any damage caused by the circuit. More often than not, these electronic components are used for control purposes.


The main function of the fuse is protection, the same way it is used for most homes. Basically, a fused is used between the main power of the car and the amplifiers. Fuses come in different ranges and level and when replacing these, it is important to get the same type of fuse that was previously used in the car audio. Otherwise, a problem can occur. A frequently blowing fuse is a way of the vehicle saying that there’s a problem and that all the electronic components must be checked out.


Capacitors are basically used to store an electrical charge within its body. There are typically two types of capacitors – the non polar and the polar. For car audio purposes, the non-polar capacitors are the ones used more often.


Diodes are used as a passage for current moving towards on direction. Because of this “one way” feature, diodes are very effective in separating current flow from each other.

Of course, these aren’t the only electronic components used for a car audio although they are the ones most often seen. These ones are also utilized in alarm systems and other vehicular functions. Aside from the functions and parts of the engine, this is one of the things that every car owner must be familiar with since it is connected with the safety of the vehicle when in use.
