Please 'Boom' Responsibly As most of you have noticed, the noise ordinances have become much tougher lately. Most of this is due to idiots, yes IDIOTS, who drive through residential areas with their windows down while their system is playing at full power. To make things worse, the music they listen to has all sorts of foul language that's not suitable for small children, (who may be playing outside). There are even a few people, who are even beyond idiot status, that play their systems at full power through residential areas after 10:00 PM (when many people go to bed). I don't believe that this type of behavior is good for the industry. If the fines get too stiff, people will stop buying large systems. If this happens, more people will get out of car audio (who wants a mediocre system). People get interested in things because they're exciting. A deck and four 6.5" speakers are not going to interest many of the younger car audio enthusiasts. If car audio enthusiasts keep annoying more and more people, the fines will keep getting tougher. All of this will only reduce interest in the equipment that fuels the industry. If you want to listen to your system at full volume, get out on the highway where there's little chance of bothering anyone. When you get to a red light, turn it down. If the only thing attractive about you is your 'system', you have some work to do. Bottom line... Think about what you're doing. Think about other people. It's not the end of the world if you have to turn the volume down for a little while.

Integrated Circuits:
An intagrated circuit (I.C.) is a group of components which may include resistors, low value capacitors and transistors printed on a silicon chip. The individual components of the I.C. make up a commonly used circuit. The circuits can range from simple voltage regulators to audio chips for a head unit to a microprocessor for a computer.
Op-amp:
The schematic diagram below shows all of the internal components printed on a tiny piece of silicon inside a popular operational amplifier. The pictures below the schematic show the actual package which contains all of the component parts shown on the schematic and a single small signal transistor. On the schematic diagram we can see that there are more than 20 small signal transistors which make up the op amp circuit. The package of the single transistor measures approximately .18" square. The measurements of the 8 pin I.C. are approx. .4" x .35". You can see that the I.C. is much smaller than 20 transistors would be. Inside of microprocessor for a computer, there are literally millions of transistors. I.C.s allow electronic devices to be much smaller and much less expensive than they would otherwise be.

This picture is to show you the difference in size between the actual piece of silicon and the size of the package. This is not an I.C., it is only a single transistor.
