Aftermarket Speakers: Coaxial and Component Systems
You can improve your vehicle's sound system by purchasing aftermarket speakers and installing them. The two most common speaker systems include coaxial and component speaker systems - coaxial being the most popular aftermarket speaker system, because you get the two separate drivers together for the price of one speaker. A coaxial speaker is a single midrange speaker with a tweeter mounted in the center of the cone. There is a capacitor wired to the tweeter, which only allows tweeter frequencies to play out of the speaker. Most aftermarket coaxial speakers are better built and have a bigger magnet than a factory speaker. This enables them to dissipate more heat and play louder. If you purchased the same size coaxial speaker as your original factory speaker then this speaker is very easy to install.
A component speaker system is another aftermarket speaker system option. These systems consist of a midrange, tweeter, and passive crossover network. A passive crossover network is an electrical circuit made up of a coil, capacitor, and resistor. It takes the signal from the head unit and breaks it into sections, sending the high frequencies to the tweeters, the midfrequencies to the midrange speakers, and the low frequencies to the midwoofers.
A typical factory system has the power of 10 to 50 watts approximately. An aftermarket component system can handle anywhere from 75 to 200 watts. Even if your vehicle comes with a component set of speakers, chances are good that they are not going to have the sound quality or the power capability of an aftermarket component set.
