This is one of the most common questions I get from first-time EMMA competitors, and it trips people up because it works differently to how you'd expect. Here's the plain-English version.
The golden rule: your receipt doesn't matter
Whether you paid full retail, scored a mate's rate, or picked your gear up second-hand, none of that determines your system's value for a budget-capped class. Every active component in your car gets matched to its standardised value in the official EMMA Value Database — essentially a locked-in manufacturer's suggested retail price — so every competitor is judged on the same footing regardless of what deal they actually got.
Why is everything priced in Euros?
EMMA is a European-founded organisation, and the Value Database that underpins every budget-capped class is a single, global list — every product's standardised value is set once, in Euros, and used identically whether the car being judged is in Germany, Australia, or anywhere else in EMMA Asia. That's what makes it possible to fairly compare an Australian-built system against one built on the other side of the world: everyone is measured against the same number, in the same currency, rather than local retail pricing or the exchange rate on the day. As a rough working budget, Entry's €3,000 cap is around $4,840 AUD and Master's €8,000 cap is around $12,900 AUD — but the actual check at registration is always done in Euros against the database, not against a converted AUD figure, so treat those AUD numbers as a planning guide, not the real limit.
What counts toward your budget cap
- Source units / head units, including external DACs or media players
- Digital Signal Processors (DSPs) and active crossovers or line drivers
- Amplifiers
- Speakers and subwoofers — tweeters, midranges, midbass drivers, subs
- Additional or auxiliary batteries, calculated by capacity and technology type
What's excluded from the cap
- Standard installation accessories and wiring/cabling
- Your car's main starter battery
- Sound damping and deadening material
- Fuse holders and passive crossovers
- Custom fabrication and labour costs
How to actually calculate it
- Go to the official EMMA Value Database.
- Search for the exact make and model of every active component and additional battery in your system.
- Add each item to build your Equipment Budget Form — the database totals the standardised value automatically.
- Print the completed form and keep it in the car. You'll need to present it at registration and again at pre-judging checks.
What if your gear isn't listed?
If you're running something new or rare that hasn't made it into the database yet, contact EMMA (info@emmaaustralia.com for Australian events) before the event with proof of the manufacturer's MSRP — a link to the official product page or a distributor price sheet is usually enough for officials to verify and add it.
Over the cap? You're not out of options
If your calculated total comes in above the Entry €3,000 cap (or your class's equivalent), you can move into Entry Unlimited instead — no budget cap, but the trade-off is more limited custom fabrication allowance than the Master classes. It's a genuinely good option for newcomers running high-end gear who don't want to compromise on equipment.
Not sure which class actually suits your build once you've run the numbers? Read our breakdown of Master vs Entry €3,000 classes. Or if you're starting your component list from scratch, our vehicle sound upgrade packages pair a DSP amp and speakers that are already well-matched — a solid, pre-valued starting point for an Entry €3,000 build.
