Car Audio Installation
Speaker location is perhaps the most important part of setting up your car audio. Determining where you are going to place your speakers is the first step you have to take. The designs of cars are such that the listener isn't placed perfectly in middle of the two speakers. What we mean to say is that the distance between the left speaker and the left ear is not the same as the right ear and the right speaker, which is a traditional audio setup. You can easily avoid this problem by making the distance between the left and right as little as possible. Some people try to place an extra speaker on the dashboard. The problem with this is that this speaker on the dashboard rips the sound into two, making for unpleasant hearing. You can try placing the audio in different locations around the car and arrive at the proper configuration for your speakers. Another mistake which commonly occurs is that people tend to go for looks rather than the sound, when it comes to car audio. Try to listen, rather than look. Some unlikely places inside your car may be the best for placing speakers.
Choosing the location of subwoofers and amplifiers is relatively easy. You can place them where you feel they will look good. One thing to keep in mind, though, is that different equipment may interfere with each other, if improperly placed. The next step is the wiring part, which is equally important. The thing with laying cables is to buy the correct cable keeping in view the capacity of the amplifier and speakers. Next in line is the installation of the head unit and amplifiers. Once you install them, you have to select the correct type of speaker enclosure. Although the choice is yours, you can try different types of enclosures and choose one which gives the best audio output. A final fine tuning, preferably with professional help and your car audio installation is done.
The Head Unit
The Head Unit is the brains of the operation. Without this component, your car audio system can't and won't work. The head unit is the central processing device in the system. The head unit controls all the functions in your car audio system. Music too loud? Turn down the volume. Too soft? Turn it up. Want more bass? Add bass input. In addition to volume, bass, etc., the head unit may contain other systems within its casing. These include: tuner, cassette, equalizer, CD or amplifier.
You see, in a home music system, where you have much more room, many stereo setups will include a separate box for each one of these components -- CD, cassette, etc. You may have a home system like that yourself. In a car, with its space limitations, these components are often crammed into one box -- the head unit. This depends upon a number of factors, such as heat, space, cosmetic design and other concerns, and every car is different.
The Amplifier
All car audio systems have an amplifier, even if it's a small one. Occasionally the amplifier will be attached to the rear of the head unit; however, in most systems it is hidden elsewhere in the car to better dissipate heat. Signal amplification is actually a two-stage process, handled by two separate components. These are the preamplifier and the power amplifier.
The preamplifier (preamp, for short) is a very tiny signal coming directly from the head unit. Whether it's reproducing a cassette signal, a CD signal, or an FM broadcast, the preamp puts out a signal that the amplifier can use. This is where the power amplifier takes over. It's the power amp's job to take the signal from the preamp and boost it into the audible range. We'll cover this in more depth in our Amplifier column in this series. Again, because of heat, most amplifiers are located away from the head unit.
The Speakers
The speakers take the boosted signal from the power amp and create sound waves. Essentially, speakers transform electrical energy (the amplified signal) into mechanical energy (the motion of the speaker cone). For now, know that all sound is vibration, which is a chain of frequencies in the air that eventually vibrate the membranes in your eardrums. Sound energy is measured in wavelengths, known as hertz, with the audible range falling between 20 to 20,000 cycles. A cycle is the distance from the top of one wavelength to the top of the next.
There are three types of speakers that produce sounds across the audible spectrum: woofers, tweeters and midrange drivers. As the name implies, the woofer reproduces the lower frequencies. The tweeter, also aptly named, replicates the highest register. The midrange handles the frequencies in between.
Auxiliary Input Devices
Components such as CD changers and equalizers, not to mention cell phones, navigation systems, MP3 players and many of the newer technologies, interface with the head unit for amplification and signal processing.

The Advantages of a BMW Bluetooth Upgrade
The Advantage of Bluetooth
If you're like many people on the go, your cell phone is on and at the ready almost every waking minute - including drive time. However, studies (and a few bitter experiences) have clearly demonstrated that attempting to use a cell phone while driving highly distracting and dangerous, posing a hazard to both driver and others on the road (in fact, in 2005, a woman in Portland, Oregon drove off a bridge and into the Willamette River while talking on a cell phone). Many states and municipalities are now passing laws prohibiting the use of cell phones while driving.
A BMW Bluetooth upgrade makes it possible - and legal - to use your cell phone while driving.
About Bluetooth
Named for the Viking king who briefly united the Scandinavian countries over a thousand years ago by the Swedish engineers who first developed it in the 1990s, Bluetooth technology actually has its roots in the work of early Gugleimo Marconi and Nicola Tesla and their pioneering work on wireless communications during the late 1800s. It is an industry standard protocol that allows wireless communication between computers, cell phones, digital cameras and more.
Unlike radio, Bluetooth is a very specific protocol for linking a variety of digital devices over a very short range; in addition, such communications can be encrypted so as to protect privacy. Today's BMW Bluetooth upgrade enables much stronger encryption to be maintained over connections that last a longer period of time (up to 23 hours and 20 minutes).
Features
With the new Bluetooth 2.1 and a headset, you'll enjoy total "hands-off" operation of your cell phone, because you can hear your incoming calls over your OEM radio, using the control buttons on your steering wheel.
This upgrade also means that you won't miss any more important calls, since it will automatically turn off any programming you may be listening to on your radio. The BMW Bluetooth upgrade is also very easy to install and very affordable. With "plug-and-play" capability, you'll be up and running in no time!

Car Stereo Speakers - A Must Buy For Your Car
Depending on the frequency which is to be reproduced, different boxes and implementations of car stereo speakers are to be used. if you intend your system to be playing continuously, then you should base your choice on the maximum RMS power. If you are looking for higher fidelity from your speakers, you should opt for car stereo speakers with a higher and wider frequency response.
Car stereo speakers which can cover all frequency ranges are needed to get the full range of sound. The deck should be able to power your component speakers if the speakers are not high performing. Connecting an amplifier to the speakers would make it compulsory to have a crossover to distribute the right frequency to the respective speaker. It should be kept in mind that the tweeter can pick up and reproduce only high pitched treble frequencies while a subwoofer accepts only the lowest frequencies.
The location of your speakers is directly related to the quality of your car's sound. If they're spread about in a haphazard manner, you will get very poor quality due to the unplanned, inconsistent interference between the speakers. When positioned correctly, it should make you think that the sound is coming from two different voices, not just from two different speakers.
Please be realistic when choosing loudspeakers. Shop for those speakers that will fit in the current space available, unless you want to go to the trouble of modifying your existing speaker holes. There are many depth considerations and complications to be aware of, particularly in doors, where speakers may interfere with windows rolling down, dashes where speakers may be limited by ducts for heat or air, and rear decks where depth is limited by torsion bars running underneath.
While subwoofers are an important part of any car audio system, don't go overboard on buying just subwoofers. There is only so much room in a car, and you need a fair amount of it to drive comfortably.
Online Car Music System Stores
On the other side of the coin use of car is no more a luxury or has remained limited to the use for only the professionals. Young-stars are now using this particular product a lot nowadays. That is why the accessories of car have gone through a sea change and all the designs have been modulated according to the demand of the age. Car audio system has now, following this trend, become an integral part of the vehicle and it is now coming with different features, new attractions, and at different price ranges. And at the same time the popularity of e-commerce has opened a new venue for shopping that is online shopping.
Keeping these facts and developments in view some of the leading stores have already opened their online shopping profile where all the categories with their respective price range and specification are posted and added with the hyperlink of the respective company background. Even some of the manufacturing companies do post their trouble shooting facts on line to prove the customer friendliness of the product as well as the liberal policy of the said company.
Customers can get the main link with the help of the search engines and can do the window shopping while being in the remote privacy of their room. People with different budgets can easily find their option without consulting a sales person. In the good stores all kind of accessories related to car system is attached with hyperlink and provided with all details and general FAQs related to that particular product and company.
Some of the popular car audio system products with a large demand are Pioneer car stereo, JVC, Panasonic Car audio, MB Quart, Q-Logic, Sony. There are many more categories to keep the customers bewildered about choosing a particular brand. Once they have selected a brand they can click at the contact button of the said sores, being displayed in the web site and accordingly through a mail can contact the sales department of the company. In some of the stores you get the benefit of purchasing an item online and to pay off by credit card or e-transaction. That saves time and manual involvement but this process has not become much popular till now, as some people still feel skeptical to disclose the credit card or debit card number on the Internet.
Some popular categories of online audio stores are as follows:
Car stereo
Car subwoofer
Car navigator
Satellite radio
i-pod Car accessories
Car DVD players
Car amplifiers
Radar detectors
Car alarms.
Nowadays the concept of online car audio system stores has become more and more popular. This fact is corroborated by the latest survey, which found that such web sites are attracting more traffic per day as compared to the status two to three years before. The only criterion for the online store sites to be popular and useful is the accessibility factor coupled with the language that should be easy and less technical.

Car Audio - A Grievous Mistake Most People Make
Not taking precautions that will either reduce the likelihood of a loss or protect yourself if such a loss happens. This loss can result from a crash, vandalism, theft or fire.
Some people can invest a lot on high end car audio equipment. Such people will look for the best way to install such audio units. They will look at all the options open to them. They will make sure they get the best bargains. But they'll not take out time to consider how they'll protect those units.
The reality only dawns on them when something happens: An accident that ruins such equipment or an outright theft. They rush to their insurance companies only to be told that they are not covered. It's then they realize they should have done a number of things in the first place. Before it happens to you, here are things you should do...
1) Get a good security system especially those that have visual deterrents. Such deterrents are good because they discourage thieves from even attempting to steal.
2) Pack your car in a well-lit area.
3) And, get a car insurance policy that will cover your car audio equipment.
I will dwell on the third. While getting your car insurance, ask and check with your insurance company before you settle for a policy. Ensure it covers all that's very important to you. Also ensure that what you get is worth the premium you pay.
What is the liability limit of the policy? If your car audio system amounts to $7600 but your limit is $4000 then you are not properly covered. Make sure of this.
When you've done this well, then the question of who to insure with arises. This is very important as it can make so much difference in your bottom line. You can lose much. You can also save a lot -- Up to $1000 or more.
Here are my favorite pages for auto insurance quotes. These will help you save a bundle...
Car DVD Players - Products You Can Make Money With
Car DVD Player sytems: you may or may not have one in your car...and you may or may not find the automotive DVD player market very interesting...but you should not overlook the profit opportunity!
More Chinese-made car DVD players were sold in the US then car DVDs players made in any other country last year. While this may not be surprising in itself what is surprising that the brand names which sold the biggest volumes weren't JVC, Kenwood, or Alpine... they were cheap car DVD players from little-known Chinese car DVD player brands.
So what is going on?
Cheap made-in-China car DVD players are flooding the consumer markets of the western world for one reason: price. Smart importers have been able to sell very low-priced consumer electronics and appliances because of their connections with Chinese traders or car DVD factories in China.
Cheap labor, improved logistics, lower priced generic electronic components, and aggressive home-grown R&D have all combined to mean China is now the cheapest and most massive producer of in-dash car TV and DVD players.
Why would consumers pay $849.99 for a brand name car DVD / CD receiver with 7 inch LCD monitor... when a discount car dvd player from China with virtually equivalent functions costs only $500 or even less? The brand names for car DVD players mean a lot to customers... but not when these kind of savings can be had.
So why should you care?
The simple fact of the matter is that selling unbranded dvd player / car audio in dash units is a great business opportunity for you.
For entrepreneurs with an eye on importing consumer products, it's a well-known fact that they need to set up a "Chinese connection", whatever the size of the business. A growing number of businesses are plunging into China's waters every day and reaping large rewards.
Consumer electronics like MP4 players, iPod accessories, or gadgets are high-demand, high profit items for resellers, whether you're trading from a small shop or selling online. Everyone loves new electronic gadgets, and because of the higher price range, your actual profits as a re-seller are healthy.
The higher perceived value of car DVD players means one automotive DVD sale can result in a $100 profit. This is considerably easier than the high-volume sales required to make a profit of smaller electronic goods and other common mass-produced consumer products.
There's a lot more that needs to be said about choosing products, analysing a market, and honing your sales methods. You owe it to yourself to take a look further into this market area while it's still a wide open opportunity. You don't need experience, specialized knowledge, or big business risks - especially if you pursue the ecommerce / dropshipping avenue.
Whether or not you choose China-made car DVD players as your big ticket item is up to you, however one thing you must do is investigate the limitless business opportunities Chinese manufacturers offer. Hundereds of people are starting successful import businesses every month. If you are interested in joining them Chinavasion will help you get started.

Buying A Car DVD Player - 7 Questions To Ask When Purchasing
The first point you will have to consider after you have decided to buy an automotive DVD player or component is whether to purchase it online or from a 'bricks and mortar' car audio store. While you are able to deal with salespeople face to face at the 'bricks and mortar' store you may find you get a much better price online from an electronics wholesaler. You will still need to ask several key questions, regardless of your decision.
Will I get all the components I need?
There is nothing worse than paying good money for a car dvd player, going to install it and finding you still need to buy the speakers, TV tuners, TV antennas, wires, brackets or other components before it can be installed. After all, what is the point of buying an in dash car TV DVD player if you don't get the tuner or aerial to make it work.
This depends on where the car DVD player is being purchased. If purchased from a bricks and mortar store then it should be offered by the vendor as electronic goods cost more at stores than they do online.
Can I connect my USB devices or flash memory cards to the player?
More music and data you want shown in vehicles is stored on computers and USB and an increasing number of car DVDs have a plug-in function. These USB ports can also be a useful point to install Bluetooth cellular car phone kits.
What formats does it support?
Will it support MP3s or MPEGs? What about AVI files? If you are choosing a system that will accept USBs and flash memory cards it is always good to check that the system will accept the format of programs you store most often on flash.
What region DVD's does this player accept?
DVD's are becoming increasingly multi-regional but that doesn't necessarily mean that every car DVD player will play every DVD. It is always a good idea to check which region of DVDs you are actually to make sure your dvd player car audio in dash unit is compatible with your collection.
How big is the screen?
The cost of LCD screens have come down a lot in last 12 months, as seen by Panasonic's 150-inch LCD screen showcased at this year's Consumer Electronics Show, which cost the same as the 109 inch screen the company put on display at the show the previous year. As a result, in dash car TV DVD players with 6.5 and 7 inch screens are considered to be the norm, and should be extremely affordable.
It's got a screen, but is it a touch screen?
We all know what a touch screen is, it is one of the things that has made the iPod such a big hit globally. Touch screens are becoming increasingly common and automotive dvds with touch screens should not be astronomically priced. After all, there is nothing worse than hunting for a tiny knob when trying to change music whilst on the road.
