Is Bigger Better in Auto Sound Systems
When it comes to auto sound systems, one question seems to be repeated often-is bigger better? The honest answer to that is not by a long shot. There are many excellent quality sound systems that will not require the backseat and your first-born in order to enjoy wonderful quality of sound and music as you drive along on your daily commute. One thing that is important to remember is that dynamite does in fact come in small packages. The same can be true of a good quality sound system for your car, truck, or SUV.
You can elect to have the full range sound package. This package, if not custom installed by the dealer can take up a great deal of real estate within your car, truck, or SUV. If you own a compact car, these types of speakers and this particular type of sound system is definitely not recommended. The first reason it is unattractive is that it will most likely require either the vast majority of your trunk or take out your back seat. I for one like being able to cart around friends, relatives, and/or children-my back seat isnt up for grabs. I also prefer the continuity of a factory-installed system that takes up none of the premium living space within the interior of my SUV.
I am personally biased towards the wonderful sound quality of the Bose sound system and speakers. The quality of sound with this particular system is excellent and any true music lover will tell you that good quality of sound is better by far than a louder sound. This is not to say that the Bose sound system will be the perfect choice for everyone to use as his or her auto sound system only that it is my first choice as a music lover.
I prefer a softer sound that has good quality to a louder sound of the substandard or even average quality on any day. The problem with most big sound systems and speakers is that they often sound hollow or tinny rather than full and robust. A good auto sound system will provide the best possible sound within the confines of the least possible space. You will probably find that you dont need to sacrifice your backseat in order to hold the speakers and while the Bose sound system for automobiles does cost more than some sound systems, it wont require a second mortgage on your home in order to afford. There are actually times in life when you get what you pay for.
The important thing to remember is that you do not have to have the most expensive, the best known, or even the biggest sound system in order to have a wonderful quality sound system in your automobile. You will not even have to have a Bose sound system in order to have a sound system that is not only excellent quality but also excellent sound. You do not need to pay an arm and a leg or any other appendages in order to have a good sound on your daily commute to work.
Music is all around us, at work, at home, on television shows. Music sets moods, sets tones, and kills moods on occasion. It only makes sense that you have good quality equipment upon which to play the music that so greatly enhances and enriches your life. If you are in the market for an auto sound system it only makes sense to listen to several before deciding on the one that will work best with your musical tastes and your desire for your vehicle sound system. Dont be misled by commission minded sales associated that think you need the latest, greatest, and most expensive toy on the market. Find a system that sounds good to you and go with that system. You do not have to go for a better sound if you find a sound you like that should be enough.

Latest Transistor In Circuit Checker latest
This simple circuit has helped me out on many occasions. It is able to check transistors, in the circuit, down to 40 ohms across the collector-base or base-emitter junctions. It can also check the output power transistors on amplifier circuits.
Circuit operation is as follows. The 555 timer ( IC1 ) is set up as a 12hz multi vibrator. The output on pin 3 drives the 4027 flip-flop ( IC2). This flip-flop divides the input frequency by two and delivers complementary voltage outputs to pin 15 and 14. The outputs are connected to LED1 and LED2 through the current limiting resistor R3. The LED’s are arranged so that when the polarity across the circuit is one way only one LED will light and when the polarity reverses the other LED will light, therefore when no transistor is connected to the tester the LED’s will alternately flash. The IC2 outputs are also connected to resistors R4 and R5 with the junction of these two resistors connected to the base of the transistor being tested. With a good transistor connected to the tester, the transistor will turn on and produce a short across the LED pair. If a good NPN transistor is connected then LED1 will flash by itself and if a good PNP transistor is connected then LED2 will flash by itself. If the transistor is open both LED’s will flash and if the transistor is shorted then neither LED will flash.

How to Dial in Your Cars Audio System
Level setting, done by ear, is more art than science. It can be done using an oscilloscope but since few people have one of those laying around well cover doing it by ear. Basically you want to start with the first component in the chain (the head unit) and work your way to the last component (the amplifier).
1. Start by turning all of the input level adjustment knobs (gain controls) on your components fully counter-clockwise (to their minimum setting). Set the tone controls (bass, treble, loudness) on your head unit to no boost (bass and treble level = 0 and loudness is off). If you have more than one RCA pair you will want to set each gain adjustment separately. Make sure your fader and balance controls are set to the channel you want to adjust first. This can be an individual channel if you have individual gain adjustments or a pair of channels if you have one gain for two channels.
2. Next set all of your equalizers settings (if you have an equalizer) to the center (detent) position so they produce no boost or cut. What we want is as pure a signal as possible.
3. Put in some good quality source material, preferably a CD with strong output and a clean recording. Hard rock would be a bad choice here. Try something cleaner, maybe acoustic, that youre familiar with.
4. Turn the decks volume up slowly until you begin to hear distortion. When you hear it, stop and back off slightly until you no longer hear it. If you dont hear distortion, even when the volume is all of the way up then you have a quality head unit. Thats what were looking for.
5. Now with your head unit at maximum undistorted volume move on to the next component. Adjust its input gain until you begin to hear distortion. Back off slightly.
6. Continue this process until you have all of the components in the chain at their maximum undistorted level.
7. When you reach the amplifiers you may need to wear earplugs to adjust them to their maximum level. As before, turn up the gain until you hear audible distortion. This should be audible even with earplugs in. But honestly, if you have to wear earplugs to listen the distortion level is probably not a factor :)
Thats it. Play some music and verify that everything sounds right. Congratulations! Youve just learned to properly adjust the settings on your car audio system.
