You’ve got a nice pearled paint job. You’ve got your 18’ sized chrome mags. You’ve got an interior job that looks like a dream. But all of that would be superficial if you don’t have a good car stereo system in your ride.
A good car stereo system is a marvel to experience, just like a poorly constructed car stereo system is such a pity to look at. The price is a big factor, but not all expensive hardware perform well if installed haphazardly, or if hooked up with incompatible hardware. It is also subjective, just as some of us find black cars more appealing than other color cars. If you like your car stereo system more than any other in the same vehicle, then you have the best.
If you like some other car stereo system more than yours in the same vehicle, then that one is better. Only you can decide which is best for you. For a car stereo system to be a good or great, it must first meet or exceed the user's expectations.
The type of vehicle also plays a major part in what kind car stereo system you should build. For some people, after only being in a few vehicles their ears recognize the inherent characteristics of this unique environment. Most of what we hear in a vehicle is a recording of the original artist in a given environment, usually in two channel stereo which can be playing in a totally different environment with the listeners placed in awkward listening positions relative to the placement of speakers. A great car stereo system is created with the understanding of acoustics, basic electronics, and the different products that are to be used.
A good idea is to gain references to compare to your auto audio system or any other and experience it live in as many different environments as possible. One of the best ways to accomplish this is to go to expos’ and conventions. As you hop from exhibit to exhibit you'll immediately notice the difference in sound characteristics of each setup. You will find some car stereo systems that you prefer over others, if not a favorite and that is the way to choose a cheap car stereo system that you like. Also ask for specs, they’ll gladly give it to you.
The benefits of aftermarket speakers are: they have a larger frequency response (more music coming through the car stereo speakers), more power handling capabilities, they will brighten your highs and increase your auto audio system bass. There are two types of CAR speakers available: the dual cone and the two way. A dual cone has a small paper cone built into a larger paper cone.
Amplifiers are the backbone of your car stereo system. Weak amplifiers damage good car stereo speakers, not the other way around. Amplifiers provides musical power and contributes greatly to the elimination of distortion and the upgrade of sound clarity. The size of the amplifiers will be proportionate to the level of power you want. You can tell a good power amp by turning the auto stereo system above half volume and still hearing clear amplification. Bear in mind that the more power you have the better control you have over your system.
A good car stereo system is something to show for. It can bring satisfaction to you, the owner, and to those who will witness it. It will also raise the quality and value of your car in case you wish to resell it.
