Duh, Its A Car Stereo!


If you are new to the car stereo market, you may find yourself overwhelmed at the sheer number of parts and accessories that can make up a top of the line car stereo system. In this article, well explore the basic components that make up a functioning car stereo system.

The Head Unit: Making It Happen


You may have seen the term head unit before and not known what exactly it was. Simply put the head unit is the part of your car stereo that actually produces the music from radio, tape, CD, or other device. But nowadays you can also get head units for your car stereo that can play DVDs or music and video from USB flash drives or memory cards. Head units have sure come a long ways from when people used to install home stereo equipment in their vehicles!

Amplifiers: Bring the Boom


While your head unit may provide its own internal amplification (which may be enough for you), at some point most car stereo enthusiasts will want to add amplifiers to the mix. Simply put, and amplifier takes a signal coming out of your head unit, and makes it louder. Be careful when shopping for amplifiers, as some of the large amps can draw over 100 amps; this may be well over what your alternator and battery can provide, and can cause damage to those components.

Speakers: Woofers, Tweeters, What?


The best head unit and amp is completely useless without speakers. Speakers, regardless of size, all do one thing: take the electrical signal coming from either the head units internal amp or your external amp and turn it into sound, usually loud sound. The different types of speakers are classified by the range of sounds they can reproduce. Tweeters, for example, only reproduce high pitches, while woofers reproduce the upper bass ranges. Midranges make midrange sounds, strangely enough, while subwoofers cover sounds from the low bass all the way down to sub sonic (those sounds you can feel but not hear). Subwoofers are usually the first candidate for external amplifiers, since they require large amounts of current to make that bone shaking bass.
