Car Audio Components

Car audio and video components have been increasing in cars recently due to the vast technology in car electronics to provide a high level of comfort and luxury. Every car (especially new) is equipped with 6 speakers and a head unit with CD/DVD player and GPS navigation system. Some car fans even upgrade their sound system with after the market subwoofer and amplifier for better sound quality. I’ll explain the main components of any car audio system below:

- Car speakers:
Car speakers actually reproduce the sound from electrical energy. Basically, there are two types of speaker "systems" that exist.

1. "Coaxial", "three way", "full-range", etc.
These speaker systems are designed to fit into the factory speaker located in your vehicle. They are often called a "speaker", but have more than one speaker, and will also contain a crossover.

2. "Components", "Seperates"
These speaker systems basically take everything from the above speaker system, and break it up into parts.

- Car subwoofers:
Car subwoofers are loudspeakers made to generate the lowest frequencies, or bass end of the audible sound range. Car subwoofers range from 4 inches in diameter all the way up to 36" meant for highly specialized scientific purposes. Subwoofer cones must move in and out with the longest possible extension because sound waves get longer as they get lower in frequency.

- Car GPS navigation systems:
Car navigation systems are an inexpensive upgrade to any vehicle. Aftermarket navigation systems use the newest technology and mapping software to get you from point “A” to point “B” without error. GPS navigation systems come with different types including Portable GPS and In Dash Navigation systems which usually include a Touch-Screen Monitor.

- Car amplifiers:
Car amplifiers are devices that take a small audio signal from a pre-amp, some power from your battery, and pass it on as a big audio signal to drive speakers. Audio amplifier power is measured in watts. The higher the watts, the more power the amplifier has. How much power you need depends on what you want out of your system. Amplifiers come with different types such as Class D Amplifiers and Multi-channel Amplifiers.
