HiFonics ZXR1000/1E

The HiFonics ZEUS ZXR1000/1E is a powerful and highly efficient Class-D mono amplifier from the ZEUS POWER EXPANSION series. With an output power of up to 1,000 watts RMS into 1 ohm, this compact power amplifier offers ample power reserves for demanding subwoofer systems.

The modern Class D circuit, featuring high-quality Infineon chipsets, delivers exceptionally high efficiency of up to 92%. This optimizes power consumption and reduces the load on the vehicle’s electrical system. Despite its high output power, the ZXR1000/1E stands out for its compact housing dimensions and high-quality construction featuring die-cast aluminum side panels.

The power amplifier was specifically designed for use with high-power subwoofers and intentionally does not include high-level inputs. The signal is transmitted via RCA connectors. An adjustable low-pass filter, a switchable subsonic filter, and a bass boost are available for customizing the sound.

An included bass-level remote control allows you to conveniently adjust the subwoofer level from the driver's seat. Other features include start-stop capability, EMC-certified Interference Free Technology (IFT), and the blue-illuminated HiFonics logo panel.

The ZEUS POWER EXPANSION series was named “PRODUCT OF THE YEAR 2025” by the trade magazine Car & HiFi in its January 2025 issue.
