Para muitos entusiastas de áudio automotivo, não há nada como saber que você tem um sistema de estúdio de classe mundial. Ter um bom áudio no carro é
uma das grandes alegrias da vida . No entanto, e se você quiser colocar seu sistema contra outros sistemas de classe mundial em uma competição? Isto é
como construir um sistema de competição de áudio de carro .
Como regra geral, para construir um sistema de áudio de carro vencedor, escolha uma liga e uma classe para competir, leia as regras dessa competição e construa seu sistema de acordo. As competições de áudio automotivo são realizadas por associações que definem as regras para as competições específicas. Existem muitas regras a serem seguidas em competições de sistemas de áudio automotivo, ligas e até classes.
O desafio é feroz e há muito o que se saber, mas vamos nos aprofundar em
o que é preciso para construir um sistema de competição de áudio automotivo .
Quais são as associações de áudio automotivo?
Essas organizações são a espinha dorsal do mundo da competição de áudio automotivo e, sem elas, não haveria competição. Eles definem as regras e os parâmetros e, para que seu sistema vença uma competição, você terá que
criá-lo de acordo com as especificações deles .
O primeiro passo para competir por áudio automotivo e construir um sistema de competição de áudio automotivo é examinar as
organizações de competição de áudio automotivo .
Associações internacionais de áudio automotivo
Existem três associações líderes de competição de áudio automotivo que realizam competições internacionais. Essas competições são abertas a qualquer pessoa que possa chegar ao evento e têm
ligas internacionais que competem por títulos mundiais e recordes mundiais.
Essas três associações são
IASCA ,
USACi , e
dB Drag Racing Association .
IASCA:The International Auto Sound Challenge Association
Esta é a maior e mais antiga associação de competição de áudio automotivo, e eles realizam seus eventos em todo o mundo. Eles estão sediados nos EUA, mas suas competições internacionais
definiram o padrão para sistemas de áudio automotivo em todo o mundo .
A IASCA realiza competições em
SPL (nível de pressão sonora) e SQ (qualidade sonora) competições internacionais.
USACi:Competição Internacional de Audiosound dos Estados Unidos
Esta associação é a segunda maior do mundo. Eles começaram nos estados como USAC, mas agora realizam competições internacionais sob USACi.
A USACi oferece aos competidores a oportunidade de competir em
ligas internacionais de SPL e SQ .
dB Drag Racing Association
A também conhecido como
"dB Drag" esta organização internacional é menor que a IASCA e a USACi, mas proporcionam uma experiência de competição única.
dB Drag oferece apenas
competições na categoria SPL , mas eles oferecem várias competições e aulas para manter a competição divertida e interessante nesta categoria.
Car Associates com sede nos EUA
Existem duas associações principais de competição de áudio automotivo que valem a pena mencionar, embora sejam apenas
sediadas exclusivamente nos EUA .
Essas duas associações são
MECA e
SPL do Centro-Oeste .
MECA:Associação de Competição de Eletrônicos Móveis
Esta é uma associação menor em comparação com as organizações internacionais. No entanto, vale a pena mencionar porque
oferece ligas de competição SPL e SQ com vários tipos de competição, construídos para tornar as competições tão divertidas e emocionantes quanto possível.
SPL do Centro-Oeste
Esta associação de competição de áudio automotivo está sediada exclusivamente no meio-oeste dos Estados Unidos e
oferece apenas competições de SPL .
Eles são uma associação pequena, mas a Midwest SPL é uma excelente organização para ficar de olho, pois está fazendo
grandes coisas para a comunidade de competição de áudio automotivo .
Quais são os formatos de competição de áudio automotivo?
As competições de áudio automotivo geralmente são compostas por dois formatos amplos de competição:
SQ e SPL .
SQ significa
Qualidade de som , e SPL significa
Nível de pressão sonora .
Esses formatos de competição têm
várias subcategorias ou classes , todos projetados explicitamente com a estrutura geral em mente.
Formatos SQ
focam na qualidade , enquanto os formatos SPL se concentram em
puro volume .
SQ – Formatos de qualidade de som
Os formatos de qualidade de som são tipicamente competições que testam a qualidade de um sistema de áudio automotivo. No passado, essas competições eram inicialmente focadas na qualidade do sistema de som, mas os concorrentes modernos têm
várias subcategorias , tudo baseado na qualidade do sistema de áudio.
Algumas das subcategorias encontradas no formato de competição SQ são as competições típicas de qualidade de som e competições que analisam
a qualidade da instalação de um sistema de áudio automotivo .
Existem competições no SQ que testam a afinação do sistema e sua capacidade de atingir altos níveis de decibéis
mantendo-se claro e atingindo todas as frequências do espectro de áudio e teste toda a gama de sons de um sistema com música em vez de apenas tons de teste.
O SQ também inclui competições para determinar
o melhor sistema de áudio geral áudio no carro, baseado em SPL e SQ, e outros fatores, como qualidade de construção, ajuste e outros fatores que entram em excelentes sistemas de áudio automotivo.
SPL – Formatos de nível de pressão sonora
Os formatos SPL são focados principalmente no desempenho de um sistema de áudio automotivo, com interesse especial no nível de pressão sonora, que
é o volume de um sistema de áudio .
The simple formats of these competitions determine which system can reach the highest decibel reading,
while others are more complicated .
The more advanced versions of the SPL competition format involve such competitions as face-off type challenges where competitors are put up against one another to determine
the best performing audio competition system .
Other SPL formats are broader and are open to multiple classes of systems ranging from amateur classes to
ultimate classes for world-class systems . The rules are simple, play music or test tones through the audio system, and ht highest decibel reading wins.
What Are the Car Audio Competition Classes?
Car audio competitions are divided into
the SPL and SQ competition formats with multiple categories and competition types in each format. Still, there is another level to car audio competition that goes further than format or category.
This complicated structure deeper level of competition in the
car audio competition classes .
A class is a bracket that a particular competition audio system will compete in
based on specific parameters and specifications of the system.
The classes separate the various competitors into
leagues that make the competition fair , ensuring that audio systems are judged fairly based on other systems of the same type, power, price range, and modification.
The classes separate the amateurs from the professionals and make it so that there are various levels of competition, making car audio competitions
accessible for everyone .
Some of the
competition classes in the SQ formal are: - Stock Class
- Street Class
- Modified Street Class
- Modified Class
- Modex Class
- Extreme Class
- and Master Class
Each class has its own
restrictions, rules, and specifications , and those competing in each category have to follow the directions explicitly or risk disqualification.
The judges of the competition decide on the competition class that an audio system competes in.
The SPL competition format is divided into classes, but the class divisions in this format are decided by the complexity and potential of a specific system.
This is known as the
“Pressure Class” method and separates systems by
collective woofer cone surface area measurements and sub amplifier power.
What Are Key Components for the Competition Car Audio Systems?
Car audio competition systems are comprised of many various components and features that
make them competition-worthy .
There are plenty of
competitions, competition formats, competition classes , and various competitive leagues to compete in, but they have something in common:the audio system.
It may sound simple that you need an audio system to compete in a car audio competition, but there are
some fundamentals of a car audio system often left out or overlooked by many beginner competitors.
This is why it is vital to understand the critical component of any car audio system, especially the ones
intended for competition , and not forget any of them when building a competition system.
Competition Speakers
The first key component of
a competition-winning car audio system is speakers . The speakers in the system are the core of how well the system performs. Without a good set of car audio speakers, the rest of the system is useless.
An excellent feature to look out for in competition-grade speakers is a high RMS rating. RMS means “Root, Mean, Square,” which is a measurement that
indicates the level of regular power that a speaker can handle according to the manufacturer’s recommendations.
A high RMS rating will mean
a better performing and overall consistent speaker . The speakers should be component speakers to get the most out of the system.
Add to a good set of component speakers with a high RMS rating
a good subwoofer , regardless of the type of competition your system is competing in.
Competition Amplifier
An amplifier is vital for a system like this as well, or there will be no clean source of power to drive the speakers and sub-woofer. So a good amp is crucial and can mean the difference between
winning and losing in a competition , especially in an SPL competition.
Competition Crossovers
A crossover system is important as well, as it will
correctly send the audio signal to the speakers that should output them.
These are the critical components of a car audio system, specially
built for competing for in-car audio competitions.
Can I Use an Existing Car Audio System for a Competition?
The world of car audio competitions is
far more forgiving than many realize.
Some competition leagues are for high-end systems or extreme car audio systems that do not even resemble cars anymore, but they’re also some leagues open to all competitors,
even for stock systems .
This means that
you can use the audio system that is already installed in your car , whether it has been used for previous competitions or if it simply the system that came with the case when you caught it.
That being said, there are considerations to make when entering an existing system into a car audio competition.
Keep in mind that
if you are using an existing upgraded system , and if you have not done any upgrades since the last competition, but the other competitors have upgraded theirs, yours may have fallen behind and may not be competitive anymore.
You may even mind yourself in a lower competition class than last year.
Something else to consider is that the stock class in any car audio competition is one of the most challenging competitions to compete in because it is
subject to the most rules and regulations of any car audio system competition.
This is because these systems must be kept entirely stock,
without any modifications or any other upgrades whatsoever . The system must also be in perfect condition and well maintained.
At the end of it,
you can use an existing audio system for a car audio competition , but remember that the competition is tough!
How Much Does It Cost to Make a Competition Car Audio System?
Competiton car audio systems can
cost anywhere from $400 to many thousands of Dollars . Some competition systems have cost as much as $330 000 on the high end of the scale.
A car audio system for a competition can be very costly, or it can be very affordable. It all depends on
the format, league, and class of competition that you are competing in.
The master class competitions require systems that cost huge amounts of money just to be competitive. In contrast,
the amateur classes can be entered by anyone with any form of upgrades to their car audio system.
The most expensive competition classes include the mater class, the extreme class, and the modified class. These classes are
the most outrageous and require the most high-end systems.
The competitions that can be entered with affordable systems are the amateur, stock, and modified stock classes. These competitions
are very accessible, even for first-time competitors .
How to Prepare for the First Car Audio Competition?
When competing for the first time in a car audio competition, there are a few things to keep in mind
when preparing to compete: Choose a competition
Choosing a format, league, and class to compete in is vital. This will help you build your audio system to win in that class, rather than arriving at the event and being bumped into a different class that you were not prepared for based on the size of your subwoofer housing.
Read the Rules
This is incredibly important. Without knowing the rules of your competition or class, you may be disqualified before you even begin.
Prepare Your System
Be sure that your system is set up correctly for competition by using meters to measure the output of your system and fine-tuning it to the perfect performance for the competition that you intend to compete in.
Have Emergency Equipment
Remember to have a piece of emergency equipment during the competition. These include a battery charger, an SPL meter, electrical tape, wire cutters, touch-up paint, soldering iron.
Even an extra speaker or two can prevent disaster on competition day and help you deal with unforeseen circumstances.
Speak to the Judges
If you can, when preparing for a competition, find and speak to a judge or former judge of car audio competitions. They will provide you with inside expertise on how to win in your specific competition format and class.
What to Improve for the Next Car Audio Competition
The best way to improve for the next competition is to learn from your mistakes and
learn from your fellow competitors .
Car audio is
a comprehensive platform of competition , there are so many aspects to it, and it is easy to become lost or not know where you may be going wrong.
Speaking to those around you for advice and taking careful note of circumstances that occur during a competition can be the push you need
to win your next event! Conclusão
To build a car audio competition system, it is crucial to
understand the associations and organizations that put the events together and set the rules and which competition to take part in.
Once you understand the associations and their rules, you can choose a competition to compete in
based on your budget and the system you already have in your car.
After that, design your audio system to compete in your chosen event and built it to win!
Choose the right system components based on your competition rules and
do your best to put together a competitive system .
You do not need to have a huge budget to build a winning system, but
a bigger budget does increase your chances of winning .
The most crucial aspect of this endeavor is to enjoy the process. So enjoy designing and building your competition car audio system, and enjoy the competition itself, and
you will keep coming back for more! References
