BMW M2 G87 sound upgrade

BMW M2 G87 + Helix Compose – An Immersive Experience Without Touching the OEM System

Kirby brought his BMW M2 G87 with Harman Kardon to MC Audio, looking for better bass, clarity, and an immersive experience—without touching the OEM system.

We used Helix Compose i7, i5 subwoofers, and MATCH DSP to deliver concert-quality sound while preserving factory perfection.

BMW M2 G87 + Helix Compose – An Immersive Experience Without Touching the OEM System

We’ve earned the trust of BMW owners across Australia by consistently delivering high-end audio upgrades without compromising their vehicle’s originality.

That’s exactly what brought Kirby—and his stunning BMW M2 G87 with Harman Kardon—to our workshop in Rockdale.

This project came to us thanks to a referral from our friends at Soundtech, who knew this level of OEM integration required specialists.

🧠 Step 1: Listen First, Install After

From our first conversation, it was clear—Kirby is a true BMW enthusiast. His request:

  • ✔️ More bass
  • ✔️ More clarity
  • ✔️ A full, immersive soundstage
  • ✔️ No compromise to the factory look or system

After exploring options, Kirby chose Helix Compose from Audiotec Fischer—a perfect match of precision and performance.

✅ Installed System:

  •  Front Door Speakers: HELIX Ci7
  • Front Tweeters: HELIX Ci7
  • Center Midrange & Tweeter: HELIX Ci7
  • Rear Door Speakers: HELIX Ci7
  •  Rear Tweeters: HELIX Ci7
  • Rear Shelf Speakers: HELIX Ci7
  • Rear Shelf Tweeters: HELIX Ci7
  • Under-Seat Subwoofers: HELIX Ci5 (2x FlexMount)
  • Amplifier: MATCH UP 10DSP with integrated MEC module
  • Wiring: OEM-specific T-harness + BMW connectors

🔇 Step 2: Strategic Sound Deadening

We started by disassembling the door and rear panels, applying targeted sound deadening in critical acoustic zones.

Every panel was reassembled with factory precision—zero rattle, no damage, total silence where it matters.

Then came the Helix Ci7 installation, with expert crossover placement to avoid disruption to the vehicle’s layout.

🔉 Step 3: Subwoofer Integration Without Touching OEM Amplifier

With all speakers upgraded and doors treated, we moved to low-end performance.

The Helix Ci5 subwoofers, mounted with FlexMount under the seats, delivered:

  • ✔️ Deep, tight bass
  • ✔️ Zero interference with OEM enclosures
  • ✔️ A cinematic low-end experience

All of this—without touching a single original wire or frame.

⚡ Step 4: MATCH UP 10DSP with MEC – OEM Signal, Unleashed

We installed the MATCH UP 10DSP, paired with Audiotec Fischer’s MEC module, which gave us:

  • Clean, full-range signal directly from the factory head unit
  • No need to cut or bypass factory wiring
  • Seamless integration with the vehicle’s electronics

It looked and functioned like it came straight from the factory, but delivered performance far beyond stock.

🎛️ Step 5: Pro Tuning, Polarity Checks, and Final EQ

On Day 5, we completed:

  • ✔️ Polarity testing
  • ✔️ DSP calibration
  • ✔️ Professional equalization
  • ✔️ Multi-channel tuning for perfect staging

We tuned the system to offer a wide, immersive sound field—sharp highs, full mids, and punchy bass, just as Kirby envisioned.

🚀 The Result: A Missile With Concert Sound

When Kirby returned to pick up his M2, his reaction was everything:

  • “Wow.” Eyes wide open, smile from ear to ear. That’s the moment we work for.

We transformed his M2 into a rolling concert hall—no compromise to the car, no damaged trim, just pure sonic performance.
