Together with

Rules for
car audio competitions

SEASON 2023-2024

SPL SHOW production by ACV –
a competition format for sound pressure and tuning, in which each participant can demonstrate mastery of controlling the audio system in their car, showing the maximum result, or a result limited by the rules of each class

General provisions

When compiling these rules, the SPL SHOW production by ACV and TUNING BY IBRAGIMOV team tried to make them as simple and understandable as possible, so that beginners would not experience any particular difficulties in learning before their first participation, and amateurs and professionals would maintain a sporting spirit.

The main idea of the rules is to be guided by logic. It’s better not to waste time looking for loopholes, but to spend it on designing and refining the audio system. Within the limits of class restrictions, what is described in the rules is allowed.

All current additions and changes to the rules are first published on the official website acv-auto.com
Safety
The safety of Participants, spectators, administrators and judges is the most important condition during the competition. Each Participant must understand the following before taking part in the competition:
- A car is a source of increased danger. The Participant must guarantee the safe operation of his car for himself and others.
- Audio systems and related components can produce very high sound pressure levels, which can cause hearing damage, injury, and poor health. The participant is obliged to prevent the negative impact of the audio system on himself and others, to ensure the safety of himself and those nearby.
- All components included in the audio system, such as speakers, amplifiers, power supplies, wiring, and their mounting structures, must be securely fastened to ensure safe operation, including preventing injury or damage in the event of an accident.
- The installed electrical equipment must meet all the requirements for safe operation, the electrical wiring must be reliably protected and secured, and have fuses. To ensure fire safety, a fire extinguisher must be in the vehicle and easily accessible.
Competition organizers, administrators and Judges are not responsible for accidents, damage, injuries, or other harm to health, as well as damage to property that occurred due to the fault or as a result of incorrect actions of the Participant or other persons.

By participating in competitions, the Participant undertakes to take full responsibility for his actions and any possible accidents, injuries or damages that may arise due to his fault or as a result of his actions.
Conduct

During the competition, the format management makes every effort to create a friendly atmosphere on the site, maintain a competitive spirit among the Participants, and a positive mood for the audience.

Participants must follow the instructions of the Judges and Organizers who coordinate their actions during the competition.

When taking part in competitions, the Participant must adhere to the norms of behavior in society, when in a public place, refrain from drinking alcohol, using obscene language, obscene music, etc.

In case of immoral behavior, rudeness, threats, insults in direct or indirect form towards other participants, Organizers or Judges, the Participant may be removed from the venue with subsequent disqualification, without refund of the participation fee. The same applies to behavior on social networks and other media spaces.
Equipment and vehicle

Equipment – all components and components of the acoustic system, such as: subwoofers and their design, as well as related to them - podiums, structures, amplifiers, batteries, etc.

The location and composition of equipment is regulated by the restrictions of each category and individual classes.

The participant is allowed to use only the equipment that is installed in the car or brought as a backup. The same equipment may not be used on two or more participating vehicles.

All power sources must be located inside the vehicle; the use of external power sources during measurement is not allowed.

The use of any pneumatic, pyrotechnic or other devices is strictly prohibited. The use of small pyrotechnic elements (smoke, small fireworks) is allowed only by prior agreement with the Organization and the judges.

All equipment in the vehicle must be securely fastened.

A car is a mass-produced vehicle duly registered with the State Traffic Safety Inspectorate. The Participant's vehicle must enter the measurement area under its own power without towing. In the event of a car breakdown and no possibility of repair on the site, you must immediately notify the Judge in order to make a decision on participation and further coordination actions.

The vehicle must have an original design of external body elements (except for the “Armored Vehicle” class). Changes to the chassis and underbody are not taken into account. For classes with "Wall" design, cosmetic changes and the installation of podiums on the outside of the car in the rear behind the B-pillar are allowed.

To improve body rigidity, it is recommended to apply vibration and noise insulation materials to internal body elements.

It is allowed to use tape (painting tape, PVC, metallized, reinforced) when gluing air ducts and dashboard joints, as well as rubber glass seals inside and outside. The use of other materials for these purposes and all types of sound insulation is prohibited. Taping body openings is prohibited.

It is prohibited to use any types of holding and tightening devices to increase the rigidity of external body elements, except for the “Armored Car” class. You can attract up to five assistants to hold.
Competition part

Participants who have expressed a desire to participate, who have reached the age of majority, are allowed to participate in the competition, using their own or a vehicle entrusted to them, with a valid driver’s license. Admission of a participant of minor age to participate in competitions in his own or a car entrusted to him only with the agreement of the Chief Judge and the Organizers.

First of all, when deciding to participate in competitions, you need to familiarize yourself with the rules and restrictions for classes, assess which classes a car with an audio system fits into.

To minimize unpleasant surprises, you need to check the functionality of the audio system in advance, select musical material according to the restrictions of the selected classes, prepare a supply of fuses, etc.

If this is your first time taking part in competitions, it would be a good idea to consult with experienced participants, competition organizers, or watch a video on this topic.

Contributions, stickers, advertising

The basic fee for participation in competitions, with pre-registration on the website, and compliance with sticker restrictions, is: 100,000 Soums for the first class and 50,000 Soums for each subsequent selected class. Without preliminary registration: 100,000 Soums for each selected class.

If the Participant’s car contains stickers with the logo or theme of brands that are partners of the format, they can be applied to the body without restrictions.

Team members representing brands that are partners of the format are allowed to participate at Basic Fees.

Participants in branded cars representing brands, installation studios and audio equipment stores that are NOT format partners are allowed a one-time participation with mandatory prior approval from the format administration. The increased fee will be 300,000 Soums for the first class and 150,000 Soums for each subsequent selected class.

If the Participant’s car contains stickers with a logo or theme of brands that are NOT partners of the format, or with any other advertising information, they can be applied with a size limitation: 20x30 cm in an amount of no more than 2 pieces in order to qualify for the Basic Fee. If the size of the stickers exceeds the restrictions, as well as fully branded cars, participation on such a car is possible only with an Increased contribution with mandatory prior approval, or remove excess stickers from the car body. It is allowed to cover the stickers with opaque vinyl (PVC) - in order not to damage the stickers on the body, just carefully roll up the protective layer of the vinyl adhesive base and stick only around the perimeter. It is important that it looks neat. Covering with masking tape, paper, newspapers and other materials is not allowed.

Participants representing installation studios and audio equipment stores must additionally notify the administration and agree with the Format Organizer about their participation in order to participate at the Basic Fee.

It is better to discuss all controversial issues with the format administration in advance. If the rules are not followed, the Judge has the right to decide to disqualify the Participant.

Any unauthorized advertising at events is prohibited. Installation of marquees, tents, flags and other advertising structures - strictly by prior agreement!

Pre-registration and confirmation of registration at the site

To take part in the competition, the Participant must go through the pre-registration procedure on the website, indicating his data. Registration for upcoming stages begins 10-15 days and ends 3-4 days before the date of the stage. Submitting your entry in advance will in many cases reduce the cost of your entry fee. If for any reason the Participant cannot attend the stage for which he registered, it would be a good idea to find a way to notify the organizers about this in advance.

On the day of the competition, the Participant must arrive at the site in advance of the start of the registration confirmation procedure, in a clean car. Find the administrators (judge) and confirm registration, receive a sticker with the Participant’s number, place the car on the site and stick the number on the windshield.

After completing registration at the site, the judges inspect the Participants’ cars for compliance with the selected classes, about which a corresponding note is made in the list of participants. During the judge's inspection, there should be no personal belongings of the Participant in the car. During the inspection, the Participant must provide the Judge with complete information about the installed system in the car. If it is not possible to inspect hard-to-reach and hidden places, it is necessary to provide photo or video confirmation of the installed components. If there is no confirmation or is in doubt, the Judge may require the element or structure to be disassembled for demonstration; if the Participant refuses, the Judge may transfer him to a higher class without restrictions.

If you provide knowingly false information about the system, a deliberate attempt to hide any elements, etc., the Participant may be disqualified by decision of the Judges.

Competitions

During the day, Participants present their cars and speaker systems on the site. The vehicle must be open and accessible for visual assessment.
In the morning, a “Silence Mode” is in effect on the site during the judging commission. During this time, participants may turn on or test their audio systems only at a minimum volume level, and turn it off at the first request, so as not to interfere with the work of the Judges.

After the start of the event, measurements begin and classes are announced, the Participants of which must drive up to the stage and perform within the announced class. All vehicles must enter the measurement area under their own power. We recommend preparing in advance, choosing a track and setting the settings. To prepare for the measurement near the stage, the Participant is given 2 minutes. If the start of a measurement is delayed, the Participant may receive a warning from the judge and a penalty of 1 point, which will be deducted from the final result. During measurement, the vehicle must be secured in place using a parking brake or anti-roll devices. Particular attention must be paid to the installation and removal of measuring equipment by Judges. It is prohibited to start driving without the permission of the Judge while the sensors are in the car; for this violation the Participant may be disqualified. After the performance, the Participant returns to his place on the site, carefully leaving the measurement area.

Participants should pay close attention to class announcements. If the Participant, for any reason, does not go to the measurement zone after the announcement of the class 3 times in which he was declared, the Participant will receive a technical failure instead of the result.

If the Participant’s equipment fails or breaks down before the measurement, or while it lasts, the Participant may have the opportunity to re-measure. Important: while in the measuring area, the Participant must demonstrate to the Judge the fact of an equipment failure - a non-working component, a lit “protection” indicator, a blown fuse, etc. Based on the information received, the Judges make a decision on the possibility of admission to re-measurement. In case of a positive decision and if it is necessary to troubleshoot, the Participant is given 15 minutes to solve technical problems; the car must be installed near the stage outside the measurement area and not interfere with other Participants. Repeated measurement The participant can receive only one time. If the breakdown recurs or another failure occurs, the Participant will be included in the technical breakdown. Incorrectly selected musical material, SMS or call when playing from a phone, and similar situations are not considered as grounds for re-measurement.

After completing the measurements in all classes, the Judges sum up the results and award the winners. The rule for group photography is that after the award ceremony, all winners must gather near the stage.

Sound pressure measurements

The most important element of the competition is the sound pressure measurements in the Participants’ cars near the stage. To record the results of the Participants, the Judges use the equipment of the SPL-LAB software and measurement complex. Measurements of the subwoofer section are carried out inside the car with the sensor installed in the “classic” place on the windshield on the passenger side - at a distance of 30 cm from the side pillar, at a height of 15 cm from the front panel. Measurements of front and rear acoustics are carried out with a microphone outside the car; the location is regulated by the rules of the selected class.

During the measurement, the participant can be inside the car or outside, using a remote head unit or remote control; the position of the Participant’s body is not regulated. In addition to the participant, up to 5 assistants (including the assistants themselves, operators, support group) can be in the measurement area, but only the participant can be in the car or near the doorway. During measurement, assistants should not interfere with another participant by blocking the monitor or by other actions. Before, during measurements, if more than 5 people are in the measurement area (with the exception of the JUDGES, HOST, OPERATOR FROM ORGANIZERS), then the defeat of this participant is automatically counted.

For the comfortable presence of spectators near the stage during measurements, the Participant is not recommended to keep the engine speed above 2500. If the engine speed exceeds 3000, the Judge may give a warning to the Participant, and in case of ignoring and repeated excess, cancel the measurement and disqualify the Participant.

The measurement process may vary depending on the time frame of the event, the number of participants, and the filling of classes. Standard version: each Participant is given one measurement to record the result, and these results will be the final ones, from which the top three winners are formed.

All measurements will be made under the conditions that: all factory door hinges, locks, trunk lid shock absorbers must be factory and working (if something does not work, from the factory fastenings and shock absorbers, the decision will be made by the chief judge).

Admission to the final

Participants who have attended at least one stage during the year and have shown any result that will be recorded in the final table are allowed to participate in the championship finals. Failure to go for measurements or a technical meeting without a recorded result will not give you access to the finals. The participant receives admission to the final in the same class in which he participated or one class higher within the same category. To determine the champion, vice champion, bronze champion of the season, the total number of points for all stages is counted:

For each 1 stage – 1 point
For first place – 3 points
For second place – 2 points
For third place – 1 point

If a participant takes several winning places in one stage, then these victories are also added to the total number of points.
Categories and classes

A battle is a separate competition between two or more participants, by prior agreement.

Each Participant can challenge two or more other Participants to a Battle in order to find out on an independent territory whose system is louder and better. To participate in the Battle, Participants, or their assistants, submit an application to the organizers in advance, all the conditions of the Battle and the stage at which it will take place are discussed. Participants pay a fee and receive a single measurement or a series of measurements under agreed conditions. The Organizer may introduce unexpected conditions for Participants to increase entertainment. The application can be either with the simplest system similar to SPL GAME classes, or with the loudest one, not necessarily according to the current rules, but the Participant’s systems must be similar in type! The number of Battles per stage is limited.

During the competition season, the Organizers may decide to change the number of categories and classes at some stages, and make amendments and additions within the framework of the current rules, which will be notified in advance on the official website and social networks.

Each Participant chooses his own category and class to participate. One Participant on one car can participate only in one class from the category. Maximum number of classes in which a Participant can take part in Stage-5

1 – Pressure measurement
2 – Front
3 – Rear
4 – GAME Pressure
5 – Front GAME

If a Participant takes part in two different cars, he can only participate in different classes within the category.

If there are less than 3 Participants entered in a class, the Judges may cancel it at the stage by notifying the Participants on site.

Voltage: no more than 18 volts

The equipment must be located in the rear of the cabin, behind the B-pillars, with no height restrictions.

Class implies any changes to the interior of the car. Remote control unit is allowed.

SPL GAME – maintaining the average sound pressure result for 30 seconds not higher than the specified volume. It is allowed to use only musical material of the Participant’s choice (without continuous sine, pauses and cuts).

Music must be played throughout the entire measurement; turning off the front speakers is not allowed. During measurement, the driver's door must be fully open. All windows must be closed.

These classes allow both amateurs and professionals to participate on equal terms. Here, the power of the equipment plays a second role; the Participant’s ability to control his audio system comes first. Therefore, it is worth taking time to train.

Throughout the measurement, the equipment records the results and the Participant sees the average result in real time. The task of the Participants in these classes is to show a result that will be as close as possible to the top value in the class, but not to exceed it.

Competitors should consider the capabilities of their system when choosing a class to ensure they have some power to spare. For example, if a Participant decided to perform in a class with an upper limit of 139.99 dB, his system should freely output 143-145 dB so that the margin allows him to “add” the volume at the right time if the Participant missed the start of the measurement and the result lags.

Exceeding the upper limit (130.00, 140.00, 150.00) in the class during measurement - the red screen lights up, this leads to elimination from the competition for prizes.

If, for example, there are five Participants in a class, two of them showed results within the class, and three Participants exceeded the upper limit and the red screen came on - then two Participants with a clear result share first and second place in the class, and the remaining three The participant is invited to re-measure to determine who will take third place. Similarly, in a situation where, for example, in a class of 129.99: two Participants will show a net result of exactly 129.99, and two Participants will show a result of 129.98 - all these Participants will be invited to re-measurement, where the first pair of Participants will determine the first and second place, and the second pair will share third and fourth place.

The organization of class measurements depends on the time frame of the event. Standard conditions: each Participant has one attempt to show the result, places are distributed based on the results of all participants.

Each Participant chooses his own class to participate. The numbers in the class name indicate the upper limit for the result in this class. One Participant in one car can participate only in one of the four classes. If a Participant takes part in two different cars, he can only participate in different classes.

SPL GAME 129.99

Upper class limit 129.99 dB

SPL GAME 139.99

Upper class limit 139.99 dB

SPL GAME 149.99

Upper class limit 149.99 dB

SPL FRONT GAME – keeping the average sound pressure result from the speakers located in the car door for 30 seconds not higher than the specified volume. Only musical material may be used

Limitation of the frequency range during measurement – from 60 Hz to 9000 Hz. During measurement, the driver's door must be fully open. The upper limit is 89.99 dB. All windows must be closed.

During the measurement, subwoofers in the cabin and speakers in the front panel should be turned off. The microphone is installed at the height of the door lock response on the pillar, with a distance of 30 cm to the side, the microphone is directed to the center of the casing.

SPL FRONT GAME 89.99

This class allows both amateurs and professionals to participate on equal terms. Here, the power of the equipment plays a second role; the Participant’s ability to control his audio system comes first. Therefore, it is worth taking time to train

EQUIPMENT LIMITATIONS

Throughout the measurement, the equipment records the results and the Participant sees the average result in real time. The Participants’ task is to show a result that will be as close as possible to the top value in the class. While the measurement is ongoing, the Participant may exceed the upper limit, but by the end of the measurement the result must be 89.99 dB or close to it. The final excess of the upper limit leads to elimination from the competition for prizes.

If, for example, there are five participants in a class, two of them have a result within the class, three participants in total limit the upper limit - then two participants with a clear result share first and second places in the class, and the participation of three participants is invited. for re-measurement to determine who will take third place. Likewise, in a situation where, for example, two participants show a net result of exactly 89.99, and two participants show a net result of 89.98 - all these participants will be invited to a re-measurement, where the first pair of participants determines first and second place, and the second pair ties third and fourth place.

SPL SHOW FRONT – determination of the loudest doors. Recording the average result of sound pressure from speakers located in the car door for 30 seconds.

Limitation of the frequency range during measurement – from 60 Hz to 9000 Hz. It is allowed to use only musical material without cuts and pauses (pure sine is prohibited). During measurement, the driver's door must be fully open. All windows must be closed. The participant must be in the cabin, completely in the driver’s seat.

If the design contains bass reflexes and other elements, they should be a solid podium or integrated into the paneling. The cladding and podium must have a finished aesthetic appearance. The door should open and close without interference - and in no case should it pinch the driver or touch the seat. The maximum thickness of the metal is no more than 25 cm. Additional structures around the cabin, moving or dismantling the steering wheel and driver's seat are prohibited. During the measurement, subwoofers in the cabin and speakers in the front panel should be turned off.

At equipment locations, it is allowed to dismantle the standard casings and install an equivalent replacement covered with decorative materials (oracal, anti-creak, etc.) or painting (painting vibration insulation is PROHIBITED). Visible vibration insulation is not allowed. If there are no speakers in the podiums, there should be decorative plugs in their places with an aesthetically finished look (painting is allowed) - but no more than 50% of the number of speakers of each type.

The microphone is installed at the height of the door lock response on the pillar, behind the face with the edge of the rear door, the microphone is aimed at the trim. There should be nothing between the speakers and the microphone. If the door does not hold open on its own, it is allowed to support the door with a jack, in the maximum open state.
