Common to all systems is the sound quality.The quality of sound in a car audio system depends upon a number of factors - the type and quality of the media player system, the type of speakers used, the acoustics of the vehicle and interference from other devices.
Type and Quality of Media Player System
A car CD player has an SNR of 90 or 100 dB.
An FM radio, cassette player, and CD player all have different measurements for these specs. To help understand these two specifications, let's compare a car tape cassette player and a car CD player.
Cassette player has an SNR of 50-70 dB. Media players in vehicles today are either radio tuner, CD player/changer, or Digital Audio player.
CD Players & Changers
An in-dash CD Player - often combined with radio tuner, WMA/MP3 player
An in-dash CD Receiver - with a multiple CD cassette / changer located elsewhere in the vehicle
When choosing a car CD player the first two things to consider are:
Digital Audio Car Systems
With most home audio systems and portable players giving crisp quality sound using digital audio, we are no longer satisfied with the flat, bland analog sound from older car audio systems.
So now you have the media player selected, what about the speaker system.
Car Speaker System
The speaker system can be thought of in two parts: the channel amplifier and the physical speaker units.
Car amplifiers power the speakers in your car stereo system to provide crisp sound quality at high volumes. Each speaker requires one channel of amplification. This gives you a standard 4-channel sound system that will rival your home audio system.
The main factors in selecting car speakers are:
Design or Speaker Type
Technical Specifications
Fitting & Mounting
Car speaker specifications are similar to home audio speakers; the main difference in technical specification to compensate for the lower power outputs of car stereo receivers.
The speaker technical specifications include sensitivity, frequency response, signal to noise ratio, power handling and impedance. Car audio speakers are either: top mounted or bottom mounted.

Ipod Car Adapters: Ten Good Reasons To Buy One
Stop flipping from station to station for a good song when you could have up to 10,000 of your iPod favorites playing from your car stereo.
Apple iPods are famous for their highest-quality sound. There are three types to choose from: wireless, jack (built-in or not), and cassette adapters. So just about anyone with any type of car can listen to their iPod while they're driving.
Your car didn't come equipped with an iPod built-in jack adapter? Your iPod car adapter will deliver your favorite songs with the clearest quality-commercial-free.
The cassette adapter will also work in older models, so you don't have to get a new car to listen to your music.
Depending on the time of year, prices for iPod car adapters can be very reasonable, (particularly around the holiday season).
The jack adapter and wireless adapter are both wire-free, decreasing the amount of clutter in your car.
