These days, all communication technology faces the
issue of privacy and identity theft, with Bluetooth
being no exception. Almost everyone knows that email
services and networks require security. What users
of Bluetooth need to realize is that Bluetooth also
requires security measures as well.
The good news for Bluetooth users is that the
security scares, like most scares, are normally over
dramatized and blown entirely out of proportion. The
truth being told, these issues are easy to manage,
with various measures already in place to provide
security for Bluetooth technology.
It’s true that there has been some Bluetooth phones
that have been hacked into. Most devices that are
hacked into are normally those that don’t have any
type of security at all.
According to Bluetooth specialists, in order to hack
into a Bluetooth device, the hacker must:
1. Force two paired devices to break their
connection.
2. Steal the packets that are used to
resend the pin.
3. Decode the pin.
Of course, the hacker must also be within range of
the device, and using very expensive developer type
equipment. Most specialists recommend that you
have a longer pin, with 8 digits being recommended.
Fundamentals of security
The “pairing process” is one of the most basic levels
of security for Bluetooth devices. Pairing, is
two or more Bluetooth devices that recognize each
other by the profiles they share – in most cases
they both must enter the same pin.
The core specifications for Bluetooth use an
encryption algorithm, which is completely and entirely
secure. Once the devices pair with each other,
they too become entirely secure.
Until they have successfully paired, the Bluetooth
devices won’t communicate with each other. Due to
this pairing process and the fact that it is short
range – Bluetooth technology is considered to be
secure.
As the news has indicated, experienced hackers
have developed ways to get around this level of
basic security. There are ways to get around this
threat, as you can install software to prevent
hackers from getting in.
With Bluetooth becoming more and more popular, it’s
really no wonder that security is always in
question. As Bluetooth gets bigger and better,
security will always be something that no one
really takes lightly.
If you’ve been concerned about Bluetooth security
in the past, rest assured that newer devices will
offer bigger and better security. Preventing
hackers from getting in is something every owner
is concerned about – and the manufacturer’s are
very aware.

How to: A Car Stereo Installation Guide
Want to save some money? Ever wonder if you could do a car stereo installation yourself? Yes, you can do it yourself! Go ahead, spend that money on your hardware! Don’t spend it on labor. Besides, doing a car stereo installation yourself can be a very rewarding experience, not to mention you can learn a lot from it too. Nothing beats the feeling of seeing your “creation” in action, running smoothly and perfectly.
But be very careful, you really won’t want to damage your expensive hardware. Well, most car audio hardware are no-brainers to install, you’d find that most of the time the parts have specially shaped sockets and slots etc. and would only fit where it’s supposed to be installed. Still, it’s best to proceed methodically.
In a car stereo installation, you have to determine what kind of rig you’re going to put into your vehicle. If you’re a beginner, it’s best you do a car stereo installation if it’s just a simple system. You may want to leave the complicated stuff to the professionals, like installing delicate equipment like LCD panels, motorized parts etc. especially if it requires the creation of custom panels and such.
Head units are one of the easiest to do in a car stereo installation. Fortunately, most units follow the same size standards (DIN). In many cars, once the factory radio is removed the aftermarket radio will fit in the hole. In many other cars, a kit is needed if the factory hole is too big, or not deep enough. In some cases the dash has to be cut. Any car stereo store should have kits required for installation.
There are two types of mounting in a car stereo installation. ISO mounting is when the radio can be screwed to existing factory radio brackets, such as in most Japanese cars. Ring mounting is when an aftermarket radio comes with a metal ring that gets mounted to the factory radio hole or aftermarket kit via bendable tabs. In many cars, dash and trim rings have to be filed to enlarge the radio hole. Once the ring is installed, the radio slides in and is held by snaps. In most cases, special tools are required to remove the radio.
Speakers are very critical in a car stereo installation. No matter how expensive your speakers are, if they are not properly installed, the sound will not be up to par.
In a simple car stereo installation, you’ll probably be using speakers that fit into a factory location. Just make sure there are no gaps or holes. Sometimes building a wood or fiberglass baffle helps reduce holes and gives you much better sound. But always be careful when using power tools around speakers. Car stereo installation warranties usually don’t cover holes in speakers.
For unconventional speaker locations, sometimes metal has to be cut. You might want to leave this to the professionals, tools like plasma cutters and pneumatics drills are required. But if you’re going to insist, a pair of metal snips (left and right cut) will do.
A car stereo installation has to put up with vibrations and other noise sources in its environment. Even though it is impossible to eliminate these completely, there are products that will greatly decrease the noise and rattling, particularly on non-luxury cars. Liners, sprays and adhesive strips and even carpeting applied onto the panels can make a world of difference.

Pimp Up Yo’ Ride! Why You Need A Good Car Stereo System.
You’ve got a nice pearled paint job. You’ve got your 18’ sized chrome mags. You’ve got an interior job that looks like a dream. But all of that would be superficial if you don’t have a good car stereo system in your ride.
A good car stereo system is a marvel to experience, just like a poorly constructed car stereo system is such a pity to look at. The price is a big factor, but not all expensive hardware perform well if installed haphazardly, or if hooked up with incompatible hardware. It is also subjective, just as some of us find black cars more appealing than other color cars. If you like your car stereo system more than any other in the same vehicle, then you have the best.
If you like some other car stereo system more than yours in the same vehicle, then that one is better. Only you can decide which is best for you. For a car stereo system to be a good or great, it must first meet or exceed the user’s expectations.
The type of vehicle also plays a major part in what kind car stereo system you should build. For some people, after only being in a few vehicles their ears recognize the inherent characteristics of this unique environment. Most of what we hear in a vehicle is a recording of the original artist in a given environment, usually in two channel stereo which can be playing in a totally different environment with the listeners placed in awkward listening positions relative to the placement of speakers. A great car stereo system is created with the understanding of acoustics, basic electronics, and the different products that are to be used.
A good idea is to gain references to compare to your auto audio system or any other and experience it live in as many different environments as possible. One of the best ways to accomplish this is to go to expos’ and conventions. As you hop from exhibit to exhibit you’ll immediately notice the difference in sound characteristics of each setup. You will find some car stereo systems that you prefer over others, if not a favorite and that is the way to choose a cheap car stereo system that you like. Also ask for specs, they’ll gladly give it to you.
The benefits of aftermarket speakers are: they have a larger frequency response (more music coming through the car stereo speakers), more power handling capabilities, they will brighten your highs and increase your auto audio system bass. There are two types of CAR speakers available: the dual cone and the two way. A dual cone has a small paper cone built into a larger paper cone.
Amplifiers are the backbone of your car stereo system. Weak amplifiers damage good car stereo speakers, not the other way around. Amplifiers provides musical power and contributes greatly to the elimination of distortion and the upgrade of sound clarity. The size of the amplifiers will be proportionate to the level of power you want. You can tell a good power amp by turning the auto stereo system above half volume and still hearing clear amplification. Bear in mind that the more power you have the better control you have over your system.
A good car stereo system is something to show for. It can bring satisfaction to you, the owner, and to those who will witness it. It will also raise the quality and value of your car in case you wish to resell it.
