Customizing car stereo systems has become a big business. Regardless of cost, many of us want to have an excellent car stereo system. High performance car stereo can be a very expensive project, but for those who value good acoustics, it is worth the money. The first component you should consider to purchase is the head unit or the deck, which is the main control center of the entire audio system, usually includes a tuner, CD player, cassette player, even a DVD player with display or a combination of these. After that you need to determine the kind of speakers you want. Be aware of how many speakers your head unit can handle. Two important things to look into about speakers are power rating and size. Usually, the Subwoofers are mounted in the trunk because of their size, other speakers, full range, mid range or tweeters are mounted in doors. Next important device in audio systems is the amplifier, which significantly improves the quality of the high volume sound of your audio system. Choose depending on how much power you want for your audio system. Than you can add MP3 integration adapters, multiple CD changers, and bass boosters. It is better if you let a professional to install all audio components into your car to ensure that your custom car stereo is mounted and wired properly for best performance. Emission Standards Factsheet from the Swedish NGO Secretariat on Acid Rain. September 2004. Emission requirements for light road vehicles have existed in the EU since the early 1970s, while the first requirements for heavy vehicles came in at the end of the 1980s. Compared with the US and some European countries (Sweden, Norway and Austria), the EU was late in introducing requirements that were strict enough to force the use of catalytic converters in petrol vehicles. The current exhaust emission requirements regulate four groups of compounds: nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO) and particulate matter (PM). Of these, carbon monoxide is less significant from the point of view of health and the environment. For light vehicles (under 3.5 tonnes) the emission standards differ depending on the engine type (petrol or diesel). Emissions of the greenhouse gas carbon dioxide are not currently regulated for any type of vehicle. The way in which the emission standards for light and heavy road vehicles in the EU have been stiffened over the years is shown in tables 1 and 2. The standards for both light and heavy vehicles are designated "Euro" and followed by a number (usually Arabic numerals for light vehicles: Euro 1, 2, 3.., and Roman numerals for heavy vehicles: Euro I, II, III..). Emission standards also exist for two and three-wheeled vehicles (motorcycles and mopeds) and for engines for non-road machinery, but these are not covered here. Test cycles Emissions are measured using a standardized test cycle that is designed to simulate real driving. For light vehicles the entire vehicle is tested and emissions are measured in g/km. For heavy vehicles the engine is bench-tested and the results are expressed in relation to the engine power (g/kWh). A vehicle or engine that is tested and approved in one EU country may then be sold throughout the union without any requirement for further testing. Light vehicles are subjected to a transient cycle in which the vehicle follows a prescribed driving pattern that includes accelerations, decelerations, changes of speed and load, etc. Outside the EU several other test cycles are used, so emission standards from different countries are not always directly comparable. In December 2003 however, the EU, US, Japan and China agreed to draw up a common scientific platform to measure and benchmark air pollution from traffic. Light vehicles The light category of vehicles covers road vehicles under 3.5 tonnes, i.e. both passenger cars and light commercial vehicles.
