MMXXVI
1 channel · class D · competition mono

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.

Why this amplifier

One channel, all the current

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.

Built around the electrical system

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.

Smart cooling

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.

Protected, not fragile

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.

“Continuous RMS only. No peak, no burst, no marketing watts.”

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.

Questions installers ask

What is the difference from the @2 ohm version?This is the @1 ohm version: it reaches its full 9000 W RMS at 1 ohm. The @2 ohm version is a different product, rated for a different load.
Which subwoofer load should I use?Any load down to 1 ohm. At 1 ohm you get 9000 W RMS, at 2 ohm 4500 W and at 4 ohm 2300 W.
Which cable and fuse?0 AWG power and ground for the battery run, an inline fuse within 20 cm of the battery sized to the cable, and a ground point on bare metal.
Do I need a second battery or a bigger alternator?At this power level, yes in most cars. If the voltage drops below 9 V the amplifier protects itself and the level falls.
What are its dimensions?392 × 219 × 74 mm. Plan the space with the fan free to move air.
