EV OWNERS, READY TO UNLOCK YOUR CAR AUDIO’S TRUE POTENTIAL?

Your EV may have a powerful high-voltage battery, but your car audio system still relies on its own low-voltage power supply, often less than 60AH , some even just 18AH! 😭😭.

When you upgrade to high-performance amplifiers, subwoofers and DSP systems, is your 12V power setup ready to keep up?

Introducing the QUATTRON High Performance Active Charger + QUATTRON LiFePO₄ Battery — a dedicated power solution designed for high-performance car audio.

🔥 WHY UPGRADE WITH QUATTRON?

✅ Add a dedicated rear battery for your high-demand audio system
✅ Support a more stable power supply when properly configured
✅ Help your amplifiers perform at their full potential
✅ Choose from 55Ah, 70Ah and 110Ah battery options
✅ Enjoy more confident, dynamic and powerful music reproduction

⚡ More power. More stability. More music.

Suitable applications may include Tesla, BYD, ZEEKR, DENZA, GWM, JAECOO and other EV models, subject to vehicle-specific compatibility checks.

🎵 Don’t just upgrade your speakers and amplifiers. Upgrade the power behind your music.

📩 Contact us to check compatibility with your EV and car audio system.
