The 2023 Audi A3 offers excellent performance and sleek European styling, but like many modern vehicles, its factory audio system leaves room for improvement.
The owner of this A3 came to MC Audio Sydney looking for more clarity, depth, and a way to fine-tune the system without replacing the original speakers. The solution? The MATCH UP 5.4DSP amplifier — compact, powerful, and perfectly tailored for OEM integration.

🔢 Installation Details:
- Plug & Play installation using vehicle-specific harness
- MATCH UP 5.4DSP amplifier installed under seat
- Factory speaker system retained
- Full DSP calibration via PC-Tool software
🌟 Why the MATCH UP 5.4DSP?
The MATCH UP 5.4DSP is a high-efficiency class D amplifier with an integrated 7-channel DSP processor. This compact powerhouse allows:
- 5 channels of power amplification
- 56-bit resolution audio processing
- Parametric EQ, crossovers, and time alignment
- Seamless integration with Audi’s OEM head unit
It brings factory audio systems to life without changing a single speaker.

🎤 Tuning Process
Once installed, we connected the amplifier to our tuning laptop and began the real magic. With PC-Tool software, we tuned:
- Equalisation per output channel
- Time alignment to driver seating position
- Level balancing for front/rear stage
- Subtle correction for cabin resonances
The result was a dramatically more immersive, punchy, and clear sound—all while keeping the original aesthetic completely untouched.
🚀 OEM+ Sound Without Replacing Speakers
This type of installation is perfect for clients who want better sound without swapping out speakers or adding a bulky subwoofer. The MATCH UP 5.4DSP offers a clean, factory-style solution with professional tuning that truly makes a difference.
