The loudspeakers in your car are the last piece in the chain that takes the audio signal from your CD player to your ears and they can make or break the sound quality of your system. The best CD player money can buy will never live up to its potential if the car speakers are poor quality or badly fitted.
For car audio systems that hope to achieve anything like true hi-fi quality, there are two main options - Multi-axial speaker systems or Component speaker systems.
Multi-axial means two or more separate speakers that share the same speaker chassis.
Typically, there will be a small tweeter (high frequency speaker) mounted on a stand-off just above the centre of a larger woofer (low frequency speaker). This is known as a "co-axial" speaker. Others may integrate three speakers (tri-axial) and occasionally four (usually called 4-way or multi-axial, not quad-axial).
A "Component Speaker System" will usually provide the very best results. Again, it is made up of several separate speakers, each designed to handle a specific group or 'band' of frequencies.
Unlike the multi-axial types, component speakers do not share a common chassis and are physically separate from each other, allowing each speaker "drive unit" to be positioned for best results.
This allows the larger car subwoofers (these provide the lowest bass frequencies and can be up to 18 inches in diameter or more, but typically 10-12 inches) to be installed where space allows, usually in the boot. The smaller mid-bass and midrange speakers and tweeters can be installed in the front doors, dashboard, A-posts or sometimes in the lower side footwell area.
The Speaker Crossover. Wherever separate speakers are handling different frequency 'bands', some way of splitting the incoming music signal and sending it to each speaker is needed. This is called "filtering" the audio signal, and the device that handles this is known as the "crossover filter", or simply the "crossover".
In multi-axial car audio speakers, the crossover is usually built in to the speaker chassis and is often simply a capacitor or a couple of electrical components at most. But with the component systems, the crossover network can be anything from a few components hidden in a small plastic box, to a very visible collection of higher quality components in a lavish perspex or metal case.
These will have been designed to specifically suit the speakers they came with (you can't just take any crossover and use it with any combination of speakers) and are inserted in the speaker cable between the amplifier (or the CD player if its own built-in amplifier is being used) and the speakers. They do not require any kind of power supply and are therefore known as "passive" crossovers.
Another form of filter network is the "active" crossover. This is sometimes in the form of a hideaway box with dials on the top of it, although nowadays quite a few CD players have a digital active crossover built in. Active crossovers must be inserted before the amplifier stage and their outputs often feed more than one car audio amplifier.
An active crossover is a powered device (i.e. it needs its own 12 volt supply) with a more complex electronic circuit than the "passive" type, and allows a lot more variation in the settings. This gives more scope for getting the sound set up really well, but also adds the risk of getting things horribly wrong! Unless you're a knowledgeable car audio enthusiast, setting up or adjusting the settings of an active crossover is something best left to a specialist installer.
