AtΒ MC Audio, every car tells a story β and Kevinβs 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:
βI want high-end sound, but I donβt want to touch the carβs factory integrity.β
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 β
- Zero electronic risk β
- Audiophile tuning β
He also brought his experience with DSP systems from other cars β this wasnβt his first upgrade. But he wanted it done right.
Component List: Our Winning Formula
To elevate the Teslaβs sound, we built a fully active system around a MATCH UP 8DSP amplifier, ensuring full control and precision tuning:
- π΅ HELIX Ci7 W165FM-S3 β 6.5β Hi-End Midrange Woofers
- πΆ HELIX Ci7 T20FM-SC β 0.75β Hi-End Tweeters
- π HELIX IK S12-DVC2 β 12β 300W RMS Slim Subwoofer
- π§ MATCH UP 8DSP β Digital Sound Processor with full PC tuning
- π§° Custom MC Audio Harness β For seamless OEM integration
- π‘οΈ STP Standardplast Sound Deadening β Acoustic treatment for doors and panels
- π§± Custom-Built Subwoofer Enclosure β Space-saving design with deep bass output
Day 1: Planning & Harness Design
Unlike other cars, Teslas donβt 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 β The Secret Weapon
A premium system is only as good as its acoustic environment.
We treated Kevinβs 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 3β5: 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-DVC2βs ideal frequency range
Kevin wanted serious low-end β we delivered with surgical precision.
Days 6β7: Full Integration & DSP Calibration
We fitted all components into the Teslaβs cabin, hidden and factory-perfect.
The MATCH UP 8DSP was then calibrated using Audiotec Fischerβs 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. Thatβs why we test every output manually before final tuning.

Day 8: Tuning the Emotion
We spent 4β6 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.
Kevinβs response?
"Itβs even better than I expected. Youβve transformed the car."
Thatβs our goal, always.
