Comment construire un système de compétition audio pour voiture
Pour de nombreux passionnés d'autoradio, rien de tel que de savoir que vous disposez d'un système de studio de classe mondiale. Avoir un bon son dans votre voiture est l'une des grandes joies de la vie . Cependant, que se passe-t-il si vous souhaitez opposer votre système à d'autres systèmes de classe mondiale lors d'une compétition ? Voici comment construire un système de compétition audio pour voiture .
En règle générale, pour construire un système audio de voiture gagnant, choisissez une ligue et une classe dans lesquelles concourir, lisez les règles de cette compétition et construisez votre système en conséquence. Les compétitions d'autoradio sont organisées par des associations qui établissent les règles des compétitions spécifiques.
Il existe de nombreuses règles à suivre dans les compétitions, les ligues et même les classes de système audio de voiture.
Le défi est féroce et il y a beaucoup à savoir, mais plongeons dans ce qu'il faut pour construire un système de compétition audio pour voiture .
Quelles sont les associations d'autoradio ?
Ces organisations sont l'épine dorsale du monde de la compétition audio embarquée, et sans elles, il n'y aurait pas de concurrence. Ils définissent les règles et les paramètres, et pour que votre système gagne dans un concours, vous devrez le construire selon leurs spécifications .
La première étape de la compétition pour l'audio embarqué et de la création d'un système de compétition audio pour voiture consiste à examiner les organisations de compétition audio pour voiture .
Associations internationales d'autoradio
Il existe trois principales associations de compétition audio automobile qui organisent des compétitions internationales. Ces compétitions sont ouvertes à tous ceux qui peuvent se rendre à l'événement, et elles ont des ligues internationales qui se disputent des titres mondiaux et records du monde.
Ces trois associations sont IASCA , USACi , et dB Drag Racing Association .
IASCA :l'association internationale du défi du son automobile
Il s'agit de la plus grande et de la plus ancienne association de compétitions audio pour voitures, et ils organisent leurs événements dans le monde entier. Ils sont basés aux États-Unis, mais leurs compétitions internationales établissent la norme pour les systèmes audio de voiture dans le monde entier .
L'IASCA organise des concours en SPL (niveau de pression acoustique) et SQ (qualité sonore) compétitions internationales.
USACi :Concours international d'audiosons des États-Unis
Cette association est la deuxième au monde. Ils ont commencé aux États-Unis sous le nom d'USAC, mais organisent maintenant des compétitions internationales sous l'USACi.
USACi offre aux concurrents la possibilité de concourir dans les ligues internationales SPL et SQ .
Association de courses de dragsters dB
A également connu sous le nom de "dB Drag", cette organisation internationale est plus petite que l'IASCA et l'USACi, mais elle offre une expérience de compétition unique.
dB Drag propose uniquement des compétitions dans la catégorie SPL , mais ils proposent plusieurs compétitions et classes pour que la compétition reste amusante et intéressante dans cette seule catégorie.
Associés automobiles basés aux États-Unis
Il existe deux principales associations de compétition audio automobile qui méritent d'être mentionnées, même si elles ne sont basées exclusivement qu'aux États-Unis .
Ces deux associations sont MECA et Midwest SPL .
MECA :Association de la concurrence en électronique mobile
Il s'agit d'une petite association par rapport aux organisations internationales. Cependant, ils méritent d'être mentionnés car ils offrent à la fois des ligues de compétition SPL et SQ avec plusieurs types de compétitions, conçues pour rendre les compétitions aussi amusantes et excitantes que possible.
SPL du Midwest
Cette association de compétitions audio pour voitures est basée uniquement dans le Midwest des États-Unis et propose uniquement des compétitions SPL .
Il s'agit d'une petite association, mais Midwest SPL est une excellente organisation à surveiller, car ils font de grandes choses pour la communauté de la compétition audio automobile .
Quels sont les formats du concours Car Audio ?
Les compétitions audio pour voiture sont généralement composées de deux grands formats de compétition :SQ et SPL .
SQ signifie Qualité sonore , et SPL signifie Niveau de pression acoustique .
Ces formats de compétition ont plusieurs sous-catégories ou classes , tous explicitement conçus avec la structure globale à l'esprit.
Les formats SQ se concentrent sur la qualité , tandis que les formats SPL se concentrent sur l'intensité sonore pure .
SQ - Formats de qualité sonore
Les formats de qualité sonore sont généralement des compétitions qui testent la qualité d'un système audio de voiture. Dans le passé, ces compétitions étaient initialement axées sur la qualité du système audio, mais les concurrents modernes ont plusieurs sous-catégories , tous basés sur la qualité du système audio.
Certaines des sous-catégories trouvées dans le format de compétition SQ sont les compétitions typiques de qualité sonore et les compétitions portant sur la qualité de l'installation d'un système audio de voiture .
Il existe des compétitions dans SQ qui testent le réglage du système et sa capacité à atteindre des niveaux de décibels élevés tout en restant clair et en atteignant toutes les fréquences du spectre audio et testez toute la gamme de sons d'un système avec de la musique plutôt que de tester uniquement des tonalités.
SQ comprend également des compétitions pour déterminer le meilleur système audio global in-car audio, based on SPL and SQ, and other factors such as build quality, tuning, and other factors that go into excellent car audio systems.
SPL – Sound Pressure Level Formats
SPL formats are focussed primarily on the performance of a car audio system, with a special interest in sound pressure level, which is how loud an audio system is .
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!
Conclusion
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!
