Stetsom Force Extreme 180,000 watts high voltage car audio amplifier

Stetsom Force Extreme teardown - 180,000W high voltage car audio amp explained inside and out.

Ever wondered how a car audio amplifier can push 180,000 watts? This deep-dive into the Stetsom Force Extreme breaks down exactly how high voltage architecture makes it possible - and why it's nothing like a traditional 12V car amp.

🔍 WHAT YOU'LL LEARN
- Why the Force Extreme runs on up to 440V and cannot be used on a standard 12V car bus
- How 20 massive IRGP4066DS IGBTs enable theoretical power output well beyond the rated spec
- The role of the 12V section - it only powers fans and control circuitry, not the audio output
- Why the amplifier is rated at 180,000W when the components are technically capable of far more
- How thermal dissipation and wiring gauge are the real limiting factors, not the IGBTs themselves
