How Is EMMA Competition Day Run?

If you've never been to an EMMA event before, the schedule can feel opaque from the outside. Here's the general shape of the day, as it plays out at Sound Quality competitions under the global EMMA rulebook.

Check-in and documentation

You'll confirm your registration, hand over your printed equipment value sheet (for budget-capped classes), and show proof of purchase for your official competition tracks if asked. This is also when your class entry gets locked in, so make sure it matches what you actually built.

Pre-judging technical checks

Before any sound quality scoring happens, your car goes through a technical inspection: charger connection is verified, your normal driving position is confirmed and your seat adjusted to how you'd actually sit and drive (judging happens from that exact position), left/right channel integrity is tested, and playback volume is calibrated using pink noise to a standardised level of around 80-85dB. This step exists purely to make sure every car is being judged on a level, comparable footing.

The very first tracks on the official disc aren't scored at all — they're a wiring check. You'll hear a simple, deliberate "left speaker... right speaker" announcement track, specifically so any channel wired backwards, or a speaker that's dead or out of phase, gets caught and fixed before real judging starts, rather than discovered halfway through a scored sound quality pass.

Installation quality judging

A separate judging pass looks at the install itself — cleanliness, fusing, cable protection and routing, component mounting, and general craftsmanship — scored against a matrix specific to your category. This is where the difference between a tidy, thoughtful install and a rushed one becomes very obvious to a judge, regardless of how good the equipment is.

Sound quality judging

This is the part most people picture: a judge sits in the car (passenger seat during qualifying rounds; single-seat judging at finals) and works through the official EMMA competition tracks, scoring things like soundstage width and depth, imaging precision, tonal accuracy and spectral balance. It's a structured, criteria-based process, not just a judge's personal music taste — though there's an unavoidable element of trained ear and experience in how those criteria get applied.

Awards

Results are tallied across install and SQ scoring for your class, and podiums are announced later in the day. Depending on the event, top qualifiers may progress toward national or international EMMA finals.
