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 is 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 comes with different types
such as Class
D Amplifiers and Multi-channel
Amplifiers.
