If you can remember a couple of decades ago car entertainment system is not that important, all people looked in a car was the appearance and performance. But things change fast; now real car lovers install new parts on their car, replace factory parts and replace them with new cool and functional parts. One of the most common elements in pimping rides right now is installing the car a new car stereo system.

Auto manufacturers nowadays may have decent factory audio system in their new car models. The system, no matter how simple or sophisticated it may be, it always has four basic components. These components is what makes up the whole system work, it includes head units, speakers, amplifiers and auxiliary input devices.

Let us start with the head unit. The head unit is like the brain of the whole system, it controls all parts of the car stereo from volume, pitch, bass, etc. It also holds the power button for all parts to function. This also has CD or cassette readers.

The amp is a signal enhancer, it is a one small apparatus attached at the back of the head unit. This apparatus make sounds louder and increases the sound of musical instrument.

The speaker is like the mouth of the system, this is where the sound is released. This transforms electrical signals to sound.

Auxiliary input devices are components of the system such as equalizers and CD changers. Modern features of this part includes more sophisticated electronic gadgets like GPS navigations systems, mp3 players etc. This part interfaces with the head unit for enhancement and processing of the electrical signals.

3 Car Stereo Components - Tips To Put Them Together

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, we'll explore the basic components that make up a functioning car stereo system.

1. 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!

2. 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.

3. 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 unit's 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 subsonics (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.

Putting It All Together

Let's review: head units take your CD or tape and convert it to electrical signals. The amplifier makes this signal larger, and finally the speakers take that signal and make sound out of it. These are the base components you need for any car stereo installation. The accessories, such as crossovers and signal isolators, may or may not be needed for your particular application.

These are the basics you need to know for all car stereo systems. Now that you have a better idea what all these different terms actually mean, you should be able to shop intelligently for your new car stereo system. Just remember, as always, while you get what you pay for, you don't necessarily have to have the absolute best (and most expensive) parts for a good sound. More often than not, a midrange product will provide the best bang for your buck. And remember, it's all modular! You don't HAVE to buy every piece all at once. You can start with the head unit, and simply wire it's built in amplifier into your factory car stereo speakers. Add a sub and an amp later if you want, or replace the factory speakers with higher quality ones, it's all up to you.

Must I turn off my powered sub for my home stereo system at the end of every day?

Every time I turn off everything including my tv and receiver, and no signal is sent to my sub, since the power switch is still on in back of the sub the LED light stays lit overnight. Will that damage my powered sub to leave the switch in on position all the time, or must it be turned off manually with everything else.

Like Gary said, see if you can plug your sub into the back of your receiver. My receiver has two outlets on the back. One for constant power to a device and the 2nd outlet (this is where my sub is plugged in) turns whatever is plugged into it on when the receiver is on and off when the receiver is turned off. It will not hurt your sub but we are in the times of "Going Green". So to help save electricity you could turn it off. May be plug it into its own power strip so you don't have to reach so far to turn it off. Also you can by wireless remotes switches for out lets. If you have good connections and a good power-strip you will not get any hhhhmmmmm...
I bought a very good power-strip and it eliminated all my speaker and sub hhhmmmmm.
