🔥 UNLEASH THE BEAST – ZEROFLEX ZF-40K | 40,000W RMS 🔥
Power. Precision. Pure Carnage.
Introducing the Zeroflex ZF-24K, the ultimate heavy hitter for those who aren’t just in the game — they ARE the game. Packing a mind-melting 24,000 watts RMS, this monster amp isn’t for the faint-hearted. It's built for bass junkies, SPL kings, and anyone mad enough to chase true wall-flexing, door-popping, eardrum-tickling power.
🔊 FEATURES THAT SLAP HARDER THAN YOUR EX’S TEXT AT 3AM 🔊
Massive 24,000W RMS @ 1 Ohm – Real numbers. No fluff. Enough power to blow your hair back and your trunk lid off.
Designed for Demons – Built with hardcore SPL in mind, this amp thrives on extreme builds and isn’t afraid of the dark side.
Full Protection Circuitry – Over-voltage, under-voltage, thermal, and short protection, because power means nothing without control.
Solid Alloy Heatsink + Advanced Cooling – Keeps things chill when your music’s melting faces.
If your idea of “loud” is scaring people three blocks away…
If your build makes the clouds part when you hit 20Hz…
If "too much power" isn’t in your vocabulary…
Then the ZF-40K was made for you.
BACKED BY ZEROFLEX. PUSHED BY PASSION.
This is not your average amp. It’s a statement. A weapon. A challenge to the laws of physics. Built by people who live and breathe car audio. Born from the streets of NZ’s loudest scenes and battle-tested by the boldest.
