2017 Team Guidelines & Procedures1) MECA teams are created by the Retail Members and Manufacturer Members to enhance their customers and employees visibility at MECA events. MECA team members can travel together, work together, and enjoy their MECA experiences more when part of a properly managed MECA team. The team is recognized when the Retail Member or Manufacturer Member pay the yearly membership fee.

2) MECA teams can be independent, and the team must pay a yearly membership fee of $50 for this official recognition and service.

3) MECA team members must tell the event registration person that they are on a team, and make sure that this is entered on their score sheet on the line that says “MECA Team”. The MECA member MUST present their membership card and make sure that their membership number is listed on the score sheet. They must do this at every event with every score sheet.

4) MECA team members must be MECA members in good standing to be listed as team members in the event results. This means that their membership must be current.

5) MECA members who are on MECA teams will have that team name listed next to their event results on the web site. This takes extra time and effort, and is much easier to process when the score sheet is properly filled out, listing the MECA team on the appropriate line.

6) MECA team registration includes one competition membership, good for one competition vehicle. A membership card will be issued to the Retail Member, Manufacturer Member, or independent team for the vehicle. This vehicle is usually for the owner of the store or manufacturer representative’s demo vehicle, but it can be assigned to one competitor, and only one com-petitor, for the season. For independent teams, the card is usually for the President or competition leader, but it can be issued to a designated team member for competition registration and privileges.

7) We have established a MECA Team Participation Award that is presented at the end of the season. It is presented to the team that has the most members entered at MECA shows throughout the season. Each member counts one time, for each event attended. This is not based on the number of entries each member makes at the show, but on the fact that they were there and competed. For example, Jimmy Loud of Team Really Loud get 1 point for being at the show, not a point for each format entered. If 5 team members enter a given event, then the team gets 5 points toward the Team Participation Award.

8) If a MECA team member is not properly recognized in the Event Results, then the team captain or team member can notify the Event Director, or Commissioner if necessary, of the mistake, or omission, and have it corrected. MECA strives to accu-rately report all event results and facts at all times.

5 “Dueling Demos” Classes

Street+, Modified, Extreme for cars and trucks. Motorcycle. MECA Kids (vehicle registration and license rules not applicable)

Sound Quality League Dueling Demos contest is intended to recognize the strongest music systems with regard to power, clarity, tonal balance, and intensity. Vehicles go head-to-head to demonstrate the most impressive audio systems.

(A) Vehicle Requirements – All Classes

(1) Vehicle must be capable of driving safely in the judging lanes (2) Vehicle must be legal: registered, licensed, and insured. (3) Vehicle and System must meet the standard safety requirements for a MECA SPL or SQL format. (4) No one may be in the vehicle during the demo. (5) Vehicles must park with front bumpers or rear bumpers (if possible) about 1’ from each other, in front of judge table. Some locations cannot house this set up, so, modifications are permitted depending on location. (6) Once parked, the Competitor has 1 minute to get out of the vehicle and prepare for the demo. (7) The Competitor may reach into the vehicle to turn system on and off, as long as they are wearing hearing protection, and their head remains outside the vehicle. (8) Maximum engine idle is 2000 RPM’s. (9) Competitor must win class, or be selected best in state and have 20 points at the conclusion of the State/Regional Finals Soundfest, to be declared State Champion. 40 points are required in the class for World Finals Soundfest eligibility.

(B) Owner Requirements – All Classes

(1) Competitors and/or someone in their family, must own the vehicle that is used in competition. Driver’s license and vehicle registration required to verify eligibility for State Championship, and/or World Finals Soundfest eligibility. Regardless of registration, a vehicle may not be used by more than one Competitor at a show. Additionally, a Competitor may not use another Competitor’s vehicle.

(C) Judging Criteria – All Classes (1) Winners are determined by “people’s choice” or Judge Panel. Crowd directed to stand by their choice after demo. The demo with the most support wins. Crowd response, i.e. applause, screaming, yelling, dancing, etc. may also be solicited. When possible, a panel of 2 to 3 judges is chosen in place of the people’s choice format. With a Judge Panel judges are required to get a 360 degree listening experience of the vehicle and not focus on just one aspect (aka, the sweet spot). (2) Competitors challenge each other, and when necessary, a bracketing system will be used.

33

(3) Contest winner determined by success in qualifying round(s), and final round(s). (4) Coin toss, drawing straws, number guessing game or other fair method determines demo order. Winner may go first, or choose to go second. (5) Each Competitor has 1 minute to play their demo. Demo may be 1 song, or multiple songs. (6) Competitors must use commercially available tracks, and may choose their song and source material. Any source is permitted. (7) Song must be played full range, with highs and mids that are audible. Songs may be “bass” songs, and do not have to have lyrics but, if they have lyrics, they must not have any foul or offensive language. (8) Any combination of open doors, windows, trunk is permitted. (9) 1st and 2nd place will be determined as competitors bracket down thru his/her division. 3rd place will be determined by the losers of the semifinal bracket going head to head.

(D) System Requirements

Street+

(1) All audio equipment excluding head unit, sound processors, and midranges and tweeters, must be mounted behind the B-pillars of the vehicle as defined by SPL Rules. Amps for midrange and tweeter speakers may be mounted in front of B-Pillars under the seats. Original factory amps are permitted wherever they are located. No external power supplements or free standing equipment permitted. (2) All speakers must remain below the window lines except for 3 sets of tweeters. Said tweeters can be no larger than 3 inches in diameter including the mounting. Horns are not considered tweeters. Only exception will be vehicles with rear deck locations. These speaker locations most likely already pass the window line from the factory. Competitors who choose to mount speakers inside the trunk, said speakers must remain within the confines of the trunk and cannot protrude from the trunk (i.e. mounting speakers to the trunk lid). For hatchback competitors, some vehicles come equipped with speakers in the hatch door. Said competitors are allowed to use this location in street, but are limited to standard size speakers for said location. Truck beds, while considered to be cargo area, are also external so any competitors choosing to mount speakers inside the bed of a truck do not qualify for Street class. (3) All speakers must be mounted to the vehicle in some form or fashion and must remain within the confines of the ICA or passenger compartment area of the vehicle. No externally mounted speakers will be allowed. (4) Door panels may be modified with the purpose to add additional speakers, but the factory door panels must be the basis for these additions. To clarify, one cannot remove the factory door panel and simply replace it with a piece of wood. (5) Street competitors are limited to 12 speakers total (subwoofers are excluded). 2-way (Co-axial), 3-way (Tri-axial), 4-way and 5-way speakers are considered 1 speaker.

Modified

(1) All audio equipment must be mounted in or on the vehicle (aka, no external power supplements or freestanding equipment). However, head unit may be held outside the vehicle or used in a podium. (2) All speakers must be mounted to the vehicle in some form or fashion. Externally mounted

34

speakers are allowed as long as there are mounted in the confines of the original shell of the vehicle. For example, roof mounted speakers are not allowed, but mounting speakers underneath the vehicle is acceptable. Externally mounted speakers cannot change the physical shape of the vehicle in any manner. Speakers mounted in the bed of a truck are acceptable as long as all aspects of the speakers and anything attached to the speakers (i.e. mounting spots, enclosure) are secure and safe. If any portion of said equipment does protrude from the truck bed, the vehicle will be placed in Extreme. Trucks with camper shells will be treated as an SUV as far as limitations on speaker

locations.(3) There are no limits to speaker locations inside the confines of the vehicle. (4) Modified competitors are limited to 28 speakers total (subwoofers are excluded). 2-way (Co-axial), 3-way (Tri-axial), 4-way and 5-way speakers are considered 1 speaker.

Extreme

(1) All Audio equipment must be mounted in or on the vehicle (aka, no external power supplements or free standing equipment). Head Unit may be held outside vehicle or used in a podium. (2) All speakers must be mounted to the vehicle. External speakers are allowed as long as they are secured safely to the vehicle. (3) Any external speakers cut or built into the body of vehicle (i.e., cutting external speakers into the metal of the body) is considered Extreme.
