When purchasing a car audio system, you should be looking for car component speakers. Component speakers are made up of a single driver and perform only within their frequency. Component speakers are used in a group with other component speakers in order to reproduce the entire sound spectrum. A component group can consist of only two drivers or four drivers and higher to form a complete system. Each component performs within its own audio band. The combined sound of the components creates the overall effect of the car audio system.
Your other choice for car speakers is to use what are called full range speakers. These speakers cover the complete range, even bass, in a single unit. We are not going to discuss full range speakers in depth, but they are considered inferior to component systems.
Kappa, Polk, and Kicker make the best component speakers on the market. Alpine component speakers are also a very desirable brand to purchase.
Choosing the right component speakers has a lot to do with size. Most cars have holes that are already made to contain your car speakers. Apart from making new holes, which is something you don’t want to take on, your car speakers have to fit in the hole that is there. Component speakers can range in size from under 1 inch to easily above 6.75 inches. One of the most common sizes for car manufacturers is 6.5 inches, but in purchasing 6.5 component speakers you have to be careful.
There are actually two 6.5 inch speaker sizes. This is because the difference occurs when breaking the size down metrically. One of the speakers is 160 or 165 mm and is commonly listed as a 6.5 size speaker. The other is 170 or 175 mm and is listed as a 6.5S or 6.75 inch speaker. Believe it or not, the distinction can be important, so remember that if you are buying these size component speakers.
The other thing that you might want to consider is sensitivity. Sensitivity measures what a speaker can yield from the amount of power it receives. If your car audio has low power, as do most factory stereos, you want speakers with high sensitivity. If your system is high powered it is probably not manufacturer standard and has a brand name amplifier or receiver, and you want speakers with low sensitivity.
These are some details and basics that you should know when picking component speakers for car audio. Remember that choosing a good surround sound system will really enhance the audio experience in your car.
