SUPER POWER AUDIODESIGNED IN ITALY
MMXXVI
45000 watt RMS.
One channel.
A single-channel amplifier built for the subwoofer stage: 45000 W RMS at 1 ohm, 23000 W RMS at 2 ohm, 12000 W RMS at 4 ohm, with high-pass, low-pass and bass boost already on board and a smart cooling system that runs the fan on temperature.

RMS AT 14.4 V · CONTINUOUS POWER, NOT BURST · ONE CHANNEL, FROM 4 Ω DOWN TO 1 Ω
Why this amplifier
45000 W RMS at 1 ohm measured at 14.4 V, 23000 W RMS at 2 ohm and 12000 W RMS at 4 ohm. The power does not collapse when the load drops: it is where you build it.
High-pass 15 – 80 Hz, low-pass 80 Hz – 10 kHz and bass boost 0 – 12 dB at 50 Hz, all adjustable on the amplifier. No external processor needed to shape the low end.
The fan is driven by temperature or by the audio signal, so the amplifier stays quiet when it is cool and moves air only when the music asks for it.
Output short circuit, high supply voltage, low supply voltage and thermal protection. Input sensitivity 200 mV and a 56 kΩ input impedance take any head unit or DSP output.

Complete the system
Before you install it
- The electrical system comes first. An amplifier of this size asks a lot of the vehicle: generous power and ground cable, an inline fuse on the power cable as close as possible to the battery, sized to the cable section you use, and a battery in good health.
- Clean chassis ground. Ground on bare metal, paint and primer removed, with the shortest possible cable. Most noise and shutdown problems start here.
- Leave it room to breathe. The aluminium body and the fan are the cooling system: never cover the amplifier with carpet, luggage or foam, and never mount it face down in a sealed cavity.
- Set the gain by ear, not to maximum. Gain is an input matching control, not a volume knob: raise it until the sound is clean and loud, and back off at the first sign of distortion.
