Those who are in the market for auto sound systems are probably well aware of the many decisions that need to be made throughout the process. Gone are the days when you went in, pointed to a box and walked out with all the pieces, parts, and components you would ever need for a really kickin' sound. The truth of the matter is that there are many pieces and parts that work together in order to create the ultimate sound system and everyone seems to have different requirements, styles, tastes, and budgets to work with. Because of this, many manufacturers of auto sound systems have wised up to the fact that some people will buy the components they need to create the sound system of their dreams piece by piece as budgets allow. This is actually a very intelligent way for customers on a budget to buy the sound system they are hoping to some day have. As a result you will find that speakers, amplifiers, sub woofers, and the actual stereo are often sold separately and at very reasonable pr...

It should then, come as no shock that Ebay is also a great place to find excellent bargains when it comes to auto sound systems. Yes, you heard that correctly.

I for one can't imagine entering into my daily commute without the sound assistance of a good auto sound system. Music in the morning is as necessary for me as oxygen and caffeine. If I live without any of those above my day is already up and running with wrong foot first. Music is a very important part of any given day for someone like me. My wake up call in the morning comes in the form of my favorite radio station and from that point on I have music as my companion for the vast majority of my morning routine. That is of course with the exception of children and husband and some of their more insistent demands for food, money, and last minute homework crisis. I will gladly take my music and tea most mornings and skip the drama. The point of all this is that I am not alone in my morning preference. If I were there wouldn't be so many variations of the music driven alarm clock. Today you can even have CD player alarm clocks in order to get you up and running to your favorite tu...

The risks of installing your own auto sound system may be greater than you realize. The fact is that there are people that are professionally trained in the installation and proper handling of these delicate sound systems for a reason. If it weren't a difficult task they wouldn't be able to demand the rather hefty price tag that most installation centers charge. The problem is that mistakes can actually cost more than the installation. If you aren't one hundred percent certain that you can handle the installation process alone it is best to leave it up to the experts. To prove my point, I will give you my very own personal story of how auto sound system installations can go horribly (well, perhaps hilariously would be the better choice of words in my particular situation) of course. You see I wanted a CD player in my mini van about 13 years ago. This was back in the dark ages when these types of sound systems were still relatively new and on the 'cutting edge' when ...

This circuit is intended as a replacement for the electronics in a partly or wholly defective autofocus driver in a slide projector. The mechanical parts in the autofocus system are assumed to be still functional. Auto Focus for Slide Projector Fig. 1 :     Most automatic focusing systems in slide projectors  are based on the use of an optical module, which comprises a small lamp, a few lenses and mirrors, and a light sensor made from two series connected light dependent resistors (LDRs), which function as a potential divider. As shown in Fig. 1, lamp La projects a narrow beam onto the centre of the slide, A, whose surface reflects it onto the LDRs. When the slide surface bulges inside or outside, the projected image on the screen is blurred, and the beam from L is received on the surface of one of the LDRs (point 2 or 3). This is detected by a motor driver circuit, which ensures that the focal distance between the objective, 0, and the slide surface is corrected to maintain a sharp...

If you spend a good deal of time in you car, and yes, the morning commute to work and the evening commute home each and every day definitely counts, you are probably more than slightly aware of the benefits of having a good auto sound system. Your sound system is your companion in your travels most of the time. Even those who have children often spend a great deal of time driving alone. For those long and sometimes lonely miles your auto sound system is the voice of reason, the energetic beat, and the information that keeps you up on current events, weather forecasts, and what is going on in the world of the rich and famous. Even if you aren't all that into music there is the wide and wonderful world of talk radio that keeps many of us informed and inflamed about issues that are important to us and causes which we feel passionately about. The proper auto sound system affects the way we hear everything that comes through our radios. It doesn't really matter if you have the lates...
