2023 Mercedes-Benz G-Wagon AMG: Complete Audio Upgrade

For this G-Wagon AMG, Sound Concept engineered a factory-clean system that delivers concert-grade clarity without compromising OEM style. The build combines Helix DSP amplification, Hertz Mille component speakers, a custom fiberglass substage, and comprehensive ResoNix dampening across the doors, floor, and cargo panels—all calibrated for a wide, stable soundstage.

System Highlights

Processing & Power

Helix DSP + multi-amplifier architecture tuned for staging, imaging, and impact
Time alignment, crossover strategy, and phase optimization to a ±2 dB target

Front Stage & Doors

Hertz Mille Legend midrange & tweeters on factory-look mounts
3D-printed rings/adapters sealed to the inner door skin for airtight mid-bass and perfect geometry
OEM-grade wiring looms and grommet passes for reliability and serviceability

Substage

Custom fiberglass enclosure integrated in cargo area, finished to match and protect storage space
Built for rigidity and proper air volume to maximize subwoofer performance

Cabin Treatment

ResoNix CLD + decoupling layers applied to doors, floor, and interior panels, lowering the noise floor and eliminating panel resonance for clearer vocals and tighter bass.

Why This Build Matters

G-Class cabins are rugged—but they're also acoustically complex. This project shows how premium results come from:

Acoustic treatment first: less road noise equals more detail at every volume
Precision fabrication: 3D-printed parts guarantee repeatable fit and airtight seals
Service-minded design: fused, loomed power and bench-tested modules placed for easy future access
Factory look preserved: all upgrades blend seamlessly with OEM trim

FAQ

Will this upgrade affect factory features or reliability?

No. We integrate through OEM pathways and grommets with loomed, fused wiring. All features remain intact and service-friendly.

What's included in tuning?

Calibrated microphone/RTA setup, time alignment, crossover/level/phase work, and listening verification to lock in imaging and tonal balance.

How long does a build like this take?

From 2–3 days (front stage + tuning) to 1–2 weeks with full fabrication and dampening, depending on scope.
