SUPER POWER AUDIODESIGNED IN ITALY
MMXXVI
9000 watt RMS.
At 1 ohm.
One channel, built for the loads that competition subwoofers present. The SP-9000.1D @1 ohm delivers its full rated power down to 1 ohm — and asks for an electrical system built to feed it: battery, alternator, cable section and fuses.

Power, measured not promised
RMS @ 14.4 V · CONTINUOUS POWER, NOT BURST · MINIMUM LOAD 1 Ω · THIS IS THE @1 OHM VERSION
Why this amplifier
A single output stage delivers 9000 W RMS into 1 ohm. No bridging, no two channels sharing a power supply: everything goes to the subwoofer.
Power like this is won or lost at the battery. Big battery, a strong alternator, generous cable section and correctly sized fuses are part of the amplifier, not accessories.
Temperature-driven fan and a thermal management system that ramps airflow only when it is needed — quiet on the street, ready when the level goes up.
Output short circuit, high and low supply voltage and thermal protection. It works between 9 V and 16 V and defends itself instead of dying quietly.

Complete the system
Before you install it
- Build the electrical system first. A healthy battery, a strong alternator and a generous cable section are what let this amplifier reach its rated power. Weak wiring means low voltage, and low voltage means protection.
- Inline main fuse within 20 cm of the battery, sized to the cable, plus a ground point on bare metal. Use 0 AWG for the battery run.
- Respect the minimum load: 1 ohm. A lower impedance triggers the protection and, if repeated, damages the output stage.
- Keep the supply between 9 V and 16 V, 12 V negative ground, and leave air around the amplifier so the fan can work. Professional installation is recommended: damage caused by improper installation is not covered by warranty.
