SUPER POWER AUDIODESIGNED IN ITALY
MMXXVI
4 × 1200 W RMS.
One amplifier, the whole system.
The biggest of the SP four-channel amplifiers: 1200 W RMS on every channel at 1 ohm. Two front and two rear speakers driven with power to spare, or two channels bridged onto a subwoofer while the other two keep the front stage.
Power, measured not promised
RMS @ 14.4 V · CONTINUOUS POWER, NOT BURST · PER CHANNEL · MINIMUM LOAD 1 Ω PER CHANNEL
Why this amplifier
Two front and two rear speakers, driven with real RMS power. One power run, one ground, one remote: less wiring in the car and less to go wrong.
Bridge two channels onto a subwoofer — 2 × 2400 W RMS at 2 ohm bridged — and keep the other two for the front speakers. A complete system with a single amplifier.
At this power level the battery, the alternator, the cable section and the fuses decide the result. Weak wiring means low voltage, and low voltage means protection.
Output short circuit, high and low supply voltage and thermal protection, with a temperature-driven fan. It works between 9 V and 16 V.

Complete the system
Before you install it
- Inline main fuse within 20 cm of the battery, sized to the cable, and a ground point on bare metal. At this power level use a generous cable section on the battery run.
- Respect the minimum load: 1 ohm per channel. Bridged, do not go below 2 ohm. A lower impedance triggers the protection and, if repeated, damages the output stage.
- Set the filters before you set the gain. High-pass on the front and rear channels, low-pass on the bridged pair if it drives a subwoofer: it protects the speakers and cleans up the sound.
- 12 V systems only, negative ground, supply between 9 V and 16 V, with air around the amplifier for the fan. Professional installation is recommended: damage caused by improper installation is not covered by warranty.
