In general make sure that if you are supposed to be paying for new car audio system components you see the box, the price, and installation materials before the company installs the your car audio systems. Many installation places will install used parts at new part prices. When buying used parts make sure you are getting a discount. Also, examine all parts before the are installed into your car. Once you drive the car of the installation company's lot you will not be able to complain, get a refund, or adjust your order. Once you drive away, you are stuck with whatever they have installed. Only through being an aggressive consumer will you get exactly what you paid for.

Head Unit good head units will have multiple RCA outputs on the back of it. Also, a modern head unit which is basically a receiver or what people call a radio should include a CD tray, and plugs to plug in put devices into like a mp3 player. If the car audio system is bad the head unit will not have RCA outputs and therefore a RCA converter will have to be installed at added cost.

Amplifier a low end or bad car audio system will have low voltage 0.5 volts or lower amplifier. Another characteristic o a bad car audio system is just one amplifier. Most decent car audio systems will have at least two amplifiers. The volume on the head unit and the amplifier should be able to be turned all the way up with out there being distortion. If there is distortion the settings can be tweaked usually by lowering the volume on both.

Speakers a good speaker system would include multiple set of speakers installed at the idea locations within the car to give an even quality sound. A speaker system will also include subwoofers, tweeters, and midrange drivers. A bad car audio system will not have all these parts and usually only has speakers. Subwoofers deal with the lower range of sound like a dog barking. Tweeters deal with high frequency sounds like a bird singing, and of course mid range devices deal with every sound in between. Without this items the sound quality of a car audio system is going to be pretty poor.

Especially in today's modern society it is important to think about the future. While you may not have any need for output devices like the ability to have satellite radio, who knows what you will like to have in the future. A characteristic of a bad car audio system is that it has 2 or less plugs of in put devices. Do not pay for car audio components which can not be easily up graded as the audio technology increases with each passing year.
