EMMA Documentation and Presentation Requirements: Master and Expert Classes

Every year I get competitors who've done the hard part — a clean, well-tuned install — and then lose points in Master or Expert class for something that has nothing to do with wiring or acoustics: they walk in with no paperwork, or they stand in front of the judging panel and can't clearly explain their own system. As you move up EMMA's install classes, the judges start scoring how well you document and present the build, not just how well you built it.

What documentation is actually required, by class

This isn't the same at every level, and a lot of competitors assume it's optional everywhere because it was optional in Entry.

• Entry and Skilled: you only need documentation for anything hidden or non-visible — if a judge can see it, you don't need a separate sheet explaining it.
• Master: documentation is required, and it's a scored line item — system documentation carries its own points in the installation matrix, alongside a separate score for how well you explain the system to the judges.
• Expert (Limited and Unlimited): detailed documentation is expected, and a formal presentation becomes part of the event — Limited gets up to 7 minutes in front of the judges, Unlimited up to 15. Both explanation-to-judges and the presentation itself carry real points, and at Unlimited level the presentation bonus is significant enough to change your placing on its own.

See Master vs Entry: EMMA classes explained and OEM vs Unlimited if you're still working out which class your build actually sits in — the documentation expectations jump with the class, not with your budget alone.

Your time in front of the panel

The Expert presentation is the one that catches people out. Seven or fifteen minutes sounds like a lot until you're standing in front of judges who've heard a hundred pitches this season. What I actually want to hear in that window:

• The signal path, in order — source, processing, amplification, drivers — not a parts list read out loud.
• Why you made the choices you made, especially anything unusual (crossover points, driver placement, an odd amp count).
• What's hidden that we can't see from outside the car, shown through diagrams or photos, not just described.
• A straight answer to a follow-up question — guessing costs you more than a gap in the paperwork does.

A neat wiring diagram you can point to while you talk gets you further than a folder of specs no one reads. We're scoring your explanation, not your printer.

If you need a hand putting a clean signal-path diagram together, I've written up how to use AI to create a car audio system diagram — a fast way to get something presentation-ready instead of a hand-drawn scribble on the day.

Where competitors leave points on the table

The most common mistake isn't bad documentation — it's none at all, because the competitor didn't know Master and above required it. I've covered the wider list of avoidable errors in what paperwork mistakes first-time EMMA competitors make most often, but on documentation specifically: bring it printed or on a device that works without venue wifi, keep it specific to your actual car rather than a generic template, and make sure it matches what the judges can physically see behind the trim. A sheet that doesn't match the car in front of them is worse than no documentation at all.

Bottom line

If you're competing in Entry or Skilled, don't overthink this — focus on the build. The moment you step up to Master, treat documentation as a scored category, not paperwork. In Expert, treat your presentation as seriously as your install; it's worth real points and it's the one part of the day that's entirely in your control on the day itself.
