Competitors may use any music format they choose. This includes test tones, sine sweeps, MP3’s, commercially available CD’s and burned CD’s. (Exception – Xtreme division must play music only.)

The music format must be played through an audio device such as CD players, CD Changers, MP3 players or hard drives.

There is an 80 Hz limit in all peak SPL classes. (Exception – Xtreme division must play music with no frequency limit.)

The competitor may have their vehicle running during the competition as long as the following requirements are met:

Only the competitor sitting on the drivers side may remain inside the vehicle during the metering process as long as proper hearing protection is used.

Competitors may choose to open their doors and/or windows of the vehicle during the metering process. Doors and other openings are not to be slammed during the metering process. (Exception – Xtreme division competitors may only roll down their windows.)

Once the SPL metering process begins, competitors will have 30 seconds to achieve their highest SPL. Any adjustments can be made to the sound system during that time. Additional runs may be allowed if time permits.

Competitors are classified by the components of their sound system and modifications to the vehicle.

All the subwoofers mounted behind the “B” pillar in the competitor’s vehicle will be counted to determine what class they can compete in. Subwoofers mounted in OEM center consoles will not be counted. Subwoofers 10” or larger mounted in front of the “B” pillar may be asked to be disconnected or inoperable during the run.

In some classes a power rating is used. The higher of the two ratings will determine a competitor’s class.

Example: Competitor “A” has 2-10” speakers and 1000 watts. The entry level class only allows for 2-10’s and 500 watts therefore the competitor would be moved up into the next class of 2-12’s and 1,000 watts. Competitor “B” has 500 watts and 2-12’s; this competitor would be in the second division because of the increased cone area.

Each competitor may compete in as many classes as they choose at an event as long as their particular audio system installation, vehicle regulation and experience meets each class’s requirements.

National level classes will be the only classes available for any prize money at the Nationals at the end of the year. To be eligible for prize money please see the “Finals” section at the end of the rule book.

In some cases a competitor meeting will take place prior to the event. It is your responsibility to know the information discussed at this meeting. Meetings will be announced prior to the event date.

Competitors caught tampering with the judging equipment will be removed from the event.

To establish a National or State Record, a competitor must beat the old record twice at the same event. The lower of the competitor’s two record-breaking scores will be used as the new record.

National & State Records are a separate feature at each event and requires an additional fee per record to enter. The same score can be used for both records.

You do not need to be a current Get Loud Productions member to set a National or State Record.

Get Loud Productions National Invitational information can be found online at www.midwestspl.com or you can contact our offices for further information.

Invitations to the Get Loud Productions Nationals will be awarded as follows:

Example: A competitor can have 12 points in Basic 1 and 8 points in Xtreme 2 to equal 20 points. They would receive 1 invite to finals. A competitor can have 12 points in Advanced 3 and 12 points in Xtreme 3 to equal 24 points. They would receive 2 invites to finals.

Equipment may not be transferred from one vehicle to another ( shared ) at Nationals

Damaged equipment may only be replaced with exact make/model equipment.

Prize money will only be paid in the following classes:

The amount of prize money offered at the finals will vary upon the amount of participation at each event and the amount of money raised leading to and for the event.

Some classes require a Max Wattage measurement to be taken. This is how Max Wattage is derived:

The judging of the event will be easy provided competitors are aware of the rules and prepare their vehicle accordingly. We encourage all competitors to fully read these rules to completely understand their intent.

When qualifying for the event the competitor will open their vehicle for the judge to place the proper measurement equipment inside their vehicle. This includes:

On the competitors first qualifying attempt, after the judge sees what class they’ll be in due to the max wattage they produced, the competitor may be allowed to re-qualify in an effort to change their wattage class or improve their score.

If there is equipment failure after the first qualifying attempt at Nationals, competitors will have a predetermined time to replace damaged equipment before they run again.

Competitors will only receive 2 qualifying attempts.

The competitor, if he/she chooses, will qualify a second time to re-establish their class or to improve their score. If the competitor’s wattage class does not change then that competitor will automatically be in that designated

class. If the competitors score improves then the higher of the two scores will be kept.

Additional qualifying attempts to change competitors class or to improve a competitors score may be allowed and subject to an additional entry fee or re-run fee.

Once all competitors have qualified for their class, the top 4 competitors in each class will compete for 1st, 2nd and 3rd place. First place qualifier goes against fourth place qualifier and second place qualifier goes against third place qualifier. The winners will advance to the final round of competition to determine the first place winner of each class at the event.

Points will be awarded to each competitor competing at an officially sanctioned Get Loud Productions event. Points are as follows:

• First Place:         5 Points

• Second Place:     4 Points

• Third Place:         3 Points

• Fourth Place:        2 Points
