For decades now, car people have always pushed their car stereos to the limit in order to produce the best sound possible. Our grandparents’ cars with their bulky and static-filled AM radios gave way to the FM broadcasts and cassette tape playing stereo’s of our parents. Now, car manufacturers are going digital with the use of not only CD players but satellite radio with MP3 playing compatibility.
The latest and hottest growing trend in car audio now is the idea of surround sound speaker systems. The thought behind it is to have all the speakers in your car set up exactly like that surround sound audio system you have in your living room. There is a reason why everyone wants one in their car. It simply sounds incredible. Here is how you can go about bringing that movie theater sound experience into your daily ride to work.
* One of the first goals to check off your list is find a stereo head unit which allows you to wire in a surround-sound processor. Since the processor will be digital, your head unit needs to supply a digital signal. You will also need fiber-optic cables. They are used to transmit digital signals between the components. If you previously purchased a nice head unit but it cannot supply digital signals, get a CD changer with fiber-optic connection. Connect the processor to the CD changer but remember that unit you will not get a surround-sound effect, if you play a CD. You can always select a surround-sound processor that converts RCA signals to digital.
* Make sure your car is equipped with a high-end CD changer and/or DVD unit that plays the software that carries the surround-sound signals.
* You should install a five-channel amplifier that can provide power for the front speakers, the rear speakers, and the subwoofers. Each corner of the car plus the subwoofers will be separate channels.
* The center channel should have a 4- to 6-inch midrange speaker and a tweeter. This type of combination should be in its own enclosure and placed in the center portion of the car’s dashboard.
* You now need to install an amplifier to run the center-channel speakers. You can get away with a two-channel amplifier played bridged mono but have it contain an electronic crossover which can be outboard, or built in to the amplifiers.
* You are now set to begin installing the speakers which will be in all four corners of the car. Some of the newer cars already have speaker locations work perfectly surround-sound setting. Older cars are a different story and will require a touch of imagination and some work. You’ll need to add a tweeter high on the pillar at shoulder height, while a midrange speaker is used in the factory-made opening in the door.
* Now that all of your speakers are in place, set the electronic crossover for the center channel. Don't play it at full range but opt instead for about 80 Hz and up for optimal sound quality.
* Once everything has been installed, adjust the system to find the perfect fit of sound quality and volume for you. Play around with the amplifier gains and then the surround sound processor for any type of tweaks you may need.
