Tesla Model S Sound Upgrade: Zero Compromises, Maximum Experience ⚑️

When Kevin brought his Tesla Model S to MC Audio, he asked for a high-end sound system without compromising the car's factory integrity. This blog showcases how we designed a custom audio solution using Helix speakers, a MATCH DSP amplifier, and a bespoke subwoofer enclosure β€” all while preserving the OEM look and ensuring no risk to Tesla’s sensitive electronics.

Tesla Model S Sound Upgrade: Zero Compromises, Maximum Experience ⚑️

AtΒ MC Audio, every car tells a story β€” and Kevin’s Tesla Model S was one of precision, passion, and preservation. A returning customer from his previous Toyota Hilux project, Kevin trusted us again. This time, he brought us his fully electric Model S with one condition:

β€œI want high-end sound, but I don’t want to touch the car’s factory integrity.”
No warranty issues. No messy installs. Just pure sound β€” the MC Audio way.

Why Tesla Owners Trust MC Audio

Tesla's sound system may be futuristic, but it often lacks emotional depth, staging, and clarity. Kevin knew what he wanted:

  • OEM+ finish βœ…
  • Zero electronic risk βœ…
  • Audiophile tuning βœ…

He also brought his experience with DSP systems from other cars β€” this wasn’t his first upgrade. But he wanted it done right.


Component List: Our Winning Formula

To elevate the Tesla’s sound, we built a fully active system around a MATCH UP 8DSP amplifier, ensuring full control and precision tuning:


Day 1: Planning & Harness Design

Unlike other cars, Teslas don’t play by standard rules. Their EV architecture means every amp connection, power tap, and ground must be perfect. No margin for error.

We manually mapped power and signal routes, since no official harness exists for the Model S.

Day 2: Soundproofing – The Secret Weapon

A premium system is only as good as its acoustic environment.
We treated Kevin’s doors and panels with STP soundproofing, reducing road noise and increasing midbass performance by over 50%.

Adapters and spacers were custom-ordered from Aerpro, ensuring a solid speaker mount with zero resonance.

Days 3–5: Building the Perfect Subwoofer Box

Tesla has no pre-made enclosures available in Australia β€” so we built one.

Over 3 days, we:

  • Measured every corner and panel
  • Chose the right MDF + acoustic materials
  • Built, sealed, and tuned the box to match the HELIX IK S12-DVC2’s ideal frequency range

Kevin wanted serious low-end β€” we delivered with surgical precision.


Days 6–7: Full Integration & DSP Calibration

We fitted all components into the Tesla’s cabin, hidden and factory-perfect.
The MATCH UP 8DSP was then calibrated using Audiotec Fischer’s PC Tools β€” the gold standard in digital sound tuning.

Polarity checks were essential β€” with custom harnesses, one inverted channel can ruin the soundstage. That’s why we test every output manually before final tuning.

Day 8: Tuning the Emotion

We spent 4–6 hours using calibrated microphones and advanced RTA analysis to sculpt the sound.
The result? A concert hall experience in a Tesla. Crisp highs, defined mids, and sub-bass that hits without distortion.

Kevin’s response?
"It’s even better than I expected. You’ve transformed the car."
That’s our goal, always.
