Car audio has moved a long way from the old standard AM/FM Radio/Tape Deck combo. Today, in-vehicle multimedia systems include DVD video, television and navigation systems with local hotspot news. Common to all systems is the sound quality.
The quality of sound in a car audio system depends upon a number of factors; the type and quality of the media player system, the type of speakers used, the acoustics of the vehicle and interference from other devices.
Type and Quality of Media Player System
Before we look at the different types of in-vehicle media players it pays to have a basic understanding of audio quality. When deciding what type of audio system to install, and also when comparing one make and model to another, there are two key specifications to consider:
Signal-to-noise ratio [SNR] - a measure of signal strength compared to background noise in the signal or equipment. Measured in decibels. The higher the dB, the better. A car CD player has an SNR of 90 or 100 dB.
Frequency response [FR] - a measure of how much of the audio spectrum, from bass to treble, gets reproduced. It's measured as a range in Hertz, and the wider the range, the better. Look for a CD player with a range of at least 10-20k Hz.
An FM radio, cassette player, and CD player all have different measurements for these specs. To help understand these two specifications, let's compare a car tape cassette player and a car CD player.
Cassette player has an SNR of 50-70 dB. This is much lower than a CD player, so the sound quality degrades at each end of the spectrum. The FR is around 30-18k Hz for a cassette player, so does not contribute as much to sound quality as the SNR.
That's why overall, a car CD player gives a much better sound than a cassette tape player.
Media players in vehicles today are either radio tuner, CD player/changer, or Digital Audio player.
CD Players & Changers
There are a number of options when it comes to playing CD's in a vehicle:
1. An in-dash CD Player - often combined with radio tuner, WMA/MP3 player
2. An in-dash CD Receiver - with a multiple CD cassette / changer located elsewhere in the vehicle
3. Connect a portable CD player to an existing in-dash audio unit using either a cable and adapter or a bluetooth wireless connection.
When choosing a car CD player the first two things to consider are:
1. Will it physically fit into the vehicle?
2. Will it integrate cosmetically with the dash and other electronics?
Most decks have standardized form factors; so fit most cars, but there are exceptions, so make sure that the deck is suited for your car. You are usually pretty safe is the car stereo is made for the same market as the source of your car.
Cosmetic integration is a little more complex, but in many cases easily resolved through customisation features. For instance, many decks allow you to change the faceplates and color of the display.
Digital Audio Car Systems
With most home audio systems and portable players giving crisp quality sound using digital audio, we are no longer satisfied with the flat, bland analog sound from older car audio systems.
If you normally store your digital music files on CD, a compatible stereo or changer is a good option. Up to 10 hours of music [250 songs] can be stored on a single disc and allows use of random shuffling and repeat options. This disadvantage is ease of use, having to load and unload from cassettes located in the boot or under seats, and the limited file formats that your stereo can play back.
So now you have the media player selected, what about the speaker system.
Car Speaker System
The speaker system can be thought of in two parts: the channel amplifier and the physical speaker units.
Car amplifiers power the speakers in your car stereo system to provide crisp sound quality at high volumes. Each speaker requires one channel of amplification. This means a 4-channel amplifier, will support four speakers. And choice of speakers is not limited either. With a range of options for your basic stereo speakers [2-channel], you can supplement the high note quality using a tweeter and the low bass notes with a sub-woofer. This gives you a standard 4-channel sound system that will rival your home audio system.
Adding to a basic car stereo option typically involves adding subwoofers, amplifiers and crossovers to tailor the output sound to personal tastes. This does not mean the result is the boorish, obnoxious bass boom boxing that invades the entire neighbourhood. A subwoofer adds quality and purity to music.
For details of specifications on each part of your system, see Go-Reviews.com - Car Electronics Section
The main factors in selecting car speakers are:
- Design or Speaker Type
- Technical Specifications
- Fitting & Mounting
Speaker design is about the combination of sound drivers for midrange, subwoofer and tweeter. Depending upon the combination, the set is known as a two-way, three-way or four-way speaker system.
Car speaker specifications are similar to home audio speakers; the main difference in technical specification to compensate for the lower power outputs of car stereo receivers. Speaker technical specifications include: sensitivity, frequency response, signal to noise ratio, power handling and impedance. We will look at these specification in more detail in subsequent articles.
The fittings and mountings are selected depending upon where you choose to position the speakers. Car audio speakers are either: top mounted or bottom mounted. Clearance depth is most important when installing new speakers in a non-factory speaker location. So check all of your components carefully before purchase.
With such a range of combinations available the Internet provides a valuable resource in car electronics reviews. Sites like Go-Reviews.com seek out reviews and consolidate the recommendations to give you a quick reference buying guide.

Internet Business Tip: Why Are You Reading When You Should Be Writing?
While you are spending your valuable time reading, studying, and listening to business advice, your competitors are stealing your customers away. Don't believe me? You will after you read this.
Less Time Reading: If you have done any sort of Internet business, or any business for that matter, you have spent a lot of time reading books and listening to tapes in your field. Most of the time these information products are teaching how to sell, how to get customers, how to market, etc...
Of course these are important, and continue to be important, but, how much are they really teaching us vs. the amount of time they are potentially wasting?
Over the past 20 years I have read over 1,000 books and articles, have listened to over 1,000 tapes and CD's and have gone to many seminars. After so much information overload, I realized that none of it was really making my business grow. The only thing that was making my business grow was building up my subscriber lists, writing many blogs, writing hundreds of articles, and advertising myself and my business.
More Time Writing:
In sports, the athletes don't spend a lot of time reading how to do their sport. They spend the majority of their time practicing, building their muscles, and refining their skills. In the entertainment field, actors and musicians don't spend their time reading how to act or sing, they spend their time acting and singing.
Shouldn't it be the same in business?
The only way to know what form of advertising is going to work for you is to keep creating ads and seeing which one's bring in the best results. The only way to know how to talk to and email clients is to continually communicate with them. The only way to gain credibility in your field is to write articles.
Some of you are going to have a natural ability to write a great article. However; How are you going to write a great article if you don't know how to write well? Simple! Write 100 or so really terrible articles until you learn how to write great ones. It's like a baseball player who has to continually strike out before he learns how to hit a ball.
The more articles you write, the more emails you send out, the more content you put on your website(s), the more blogs you create, and the more message boards you give advice in, the more you're going to be known and recognized. Once that happens, you will be able to profit greatly on the Internet.
Strategic Times to Read and Listen to Business Advice:
Reading articles and listening to tapes is a very valuable form of education. Instead of tapes, though, I now listen to business and marketing podcasts (If you don't know what they are you should do a Google or Wikipedia Search.)
With that said, I will only listen to podcasts when I'm in the car, and I'll read print outs of articles and e-books at times when it is impossible for me to be doing business at my computer.
Summing it all Up:
You will be surprised at how much quicker your business will grow when you spend time creating. If you are new to Internet Business, it would be a great idea to start a journal detailing the steps you are taking. You can use this journal later, to help get ideas for creating future articles and content. Sometimes the articles on what doesn't work are better than the one's on what do.

Be Creative
People all around the world exchange words of love. Wonder how many people must have expressed these words of love? Mostly people say it in a simple way "I love you" with a bouquet of flower or a soft kiss. It is not a new notion but something that has been done since ages. Each one of us falls in love and find out ways to express our love. Yet there are married couples who often remind each other that they love one another in different ways. Most of the people go for the normal way of expressing their feelings.
But there are great lovers who adopt various methods to shoe their emotions. Conveying your love in such a different style makes your love life interesting and exciting and as often said interest and excitement are essential for a relationship especially that this not very new.
Instead of simply saying three words "I love you" do something new to express these words. There are various ways of articulating your love. Be creative and come up with innovative ideas. You could do some creative writing and stick it on the bathroom door so that early morning he or she receives your love note and is filled with a smile early morning.
A wonderful suggestion is to request your mate's favorite song along with a love message on a radio station that could be played while he is driving home tired from his work. Such an act of yours will help vanish his tiredness and make him feel refreshed. You could also assort songs that you both like in a CD or a cassette player and give her while she is going for work. It will make her active and in high spirits.
Being creative adds freshness to a relationship. If such steps are not taken it makes a quite boring. Couples in a relationship do require some kind of change otherwise their relationship gets monotonous. Just expressing your love in a different way is in itself a change. You should be creative and not consider such actions as immature or childish. They are just a way to make your relationship filled with excitement and entertainment. It is a life living with a difference.

What is The SGR Program?
The SGR Program
There is some confusion about what the SGR Program is about (previously the Official Secret Seminar). Is it a seminar? Is it an affiliate program?
In short the SGR Program is 2 things:
1. A powerful home SEMINAR PROGRAM that allows you to understand the LAW OF ATTRACTION
2. As a bonus, there is an opportunity to share this knowledge and get rewarded for it. An AFFILIATE PROGRAM
1. The SEMINAR PROGRAM
Master the Law of Attraction with a 180 page seminar workbook The Seminar is exclusively a personal growth program that follows the principles of the book by Wallace Wattles called "The Science of Getting Rich". It is a "pragmatic" book that actually goes more into the psychology of wealth than anything else. That wealth may be financial but could equally be spiritual wealth, emotional wealth or any other thing you would like in abundance. Specifically, it leverages the Law of Attraction. You can study the workbook and answer the related questions in each section.
Listen to the CDs on the road (or included MP3 player preloaded with the CD content) There are 10 CD's with 15 hours of content so you can listen, revise or learn while on the road. Alternatively, there is an MP3 player included with the CD content preloaded. Perfect for active pursuits where CD's won't suffice like running.
Expand your experience with a $500 live seminar gift certificate One of the best ways to learn is to place yourself in an emersive and interactive experience of the content you want to learn. The $500 live seminar gift certificate is a great way to do this. It is included in the program.
The contents of the program is TOTALLY about personal growth (ie. No affiliate stuff). Just to reiterate really. The program is about personal growth. No marketing techniques or tools, no sales copy, nothing.
2. The AFFILIATE PROGRAM As an option, if you feel like you would like to share the information you learn about the Law of Attraction, there is an OPTIONAL component that allows you to market the kit to others.
If you choose to participate, you have to sign up online. It is designed to be a simple, turnkey solution that would appeal to both the Internet Marketing novice as well as the marketing expert. Within 2 mintues, you can have a pre-built website with all the supporting tools to market online straight away. These include templates, autoresponders, sales copy, example articles and news and even a support forum for those affiliates. There is also training material for those new to Internet marketing.
If you are experienced at online marketing, everything is fully customizable. You can edit the actual website code, all the articles, the autoresponder etc. You still have access to the forum and training material etc.
In either case you can earn US$500 for every Tier one sale and US$250 for every Tier 2 sale. The break even point is pretty low given the hype and momentum The Secret already has. I have seen the Google adwords price for key words go up 10x in the last 10 days alone.
Summary: Hopefully that clears things up a bit. If you want to learn the Law of Attraction, the principles by which the movie, The Secret, was made, it is all there for you in the seminar. If you want to attract wealth into your life. The tools are online and available when you want.
Originally I wrote a short slide show to answer this question. I highly recommend you view the slideshow because there are screen shots etc that are worth viewing. See the blog for the link.
