Unlike clothing, books, or games, car customization isn’t something that will get shoved to the back of the closet or put away and forgotten about. When you help upgrade someone’s vehicle, you enhance their daily life. Their new mobile electronics will go with them on their commute, road trips, and to the grocery store. From eliminating driving hassles with in dash navigation to taking the bitter chill of wintery mornings with a remote car starter, the gift of car customization just keeps on giving!

“Borrowing” your giftee’s car and dropping it off at the car electronics shop is a simple way to get your car enhancement present installed on the sly, but you can also purchase components for installation at a later date. And don’t forget, if you aren’t sure what kind of mobile video or car stereo upgrade your loved one would want, many car electronics shops offer gift certificates. So visit your car audio video store today to get the perfect present for the audiophile or car lover on your list. Your present is sure to be this year’s absolute favorite!

If you have ever been frustrated by the lack of connection between the electrics in your car or thought that things could be simpler somehow, then getting a Bluetooth car audio system might make you feel better. Bluetooth, as we all know from our phones and wireless headsets, allows short distance communication between electronic items. In terms of car stereos, this means that you can link your mp3 player, phone or even your lap top to your stereo, making things a lot simpler.

Car Audio systems often suffer from the problem that transferring music into them can be difficult or time consuming. Even the traditional CDs and the older cassettes take up a lot of space that could be used for other purposes and it’s often nicer to listen to what you want, when you want to, rather than be at the mercy of radio DJs.

iPods and mp3 players require adaptors and possibly complicated rewiring of certain parts in order to plug them in; it’s the same with USBs. This leads to trailing cables that can easily get in your way or tangled up in each other.

Bluetooth car stereos eliminate the issues of in car phone calls by transferring all your contacts onto the display and even, in some cases, reading out the names so you don’t even need to look away from the road. They automatically mute the music in order to put calls through without you having to touch your phone. The technology is simple to use and efficient.

If your mp3 player doesn’t have Bluetooth though, it’s not a huge problem. Most Bluetooth stereo systems will have a jack ready for connection with mp3 players and iPods. This means that you do not need complicated adaptors, just simple linking cables. Or, if you prefer, there are Bluetooth adaptors that can be plugged into devices to link them up.

Some people think a 200 watt speaker will be louder than a 100 watt speaker, the greater the amplifier’s power the louder will be the sound. This isn’t necessarily so.

Speakers are the single most important part of a vehicle’s sound system and their installation should only be done by experienced installers. To get good sound you must have a good speaker system. But what makes a good speaker system? To answer this we need to look first at what sound is.

Sound theory

Sound consists of vibrations which travel through air. These vibrations are transmitted by compression and refraction waves, and sounds are heard when these waves reach the ear. Whether deep or high-pitched noises are heard depends on the frequency of the vibrations. The very lowest sound frequency which the human ear can detect is about 20 Hertz (or in other words, 20 vibration waves per second). At the other end of the scale a young person can hear frequencies of up to 20,000 Hertz (20 kilohertz). Twenty Hz is the deepest rumbling sound of an earthquake, while 20,000 Hz is the highest of screams which shatter glass.

Unlike other sound reproducers like cassettes, a CD player (and its amplifier) can reproduce sound all the way from 20 Hz to 20,000 Hz. Speakers produce the pressure variations in the air by vibrating their cones back and forth. A speaker cone vibrating 1000 times per second produces a sound frequency of 1000 Hz. One vibrating twice as fast produces a higher pitched sound. When reproducing music the speaker’s cone changes very rapidly in its vibrating frequency as it produces all the different sounds. The loudness of the sound produced depends not on how quickly the speaker’s cone vibrates but how far the cone moves. So a loud, deep bass note requires the speaker to vibrate only relatively slowly (only say 50 times per second) but to have a fairly great cone excursion.
