HiFonics ZXR750/1E

The HiFonics ZXR750/1E from the ZEUS POWER E Series is a powerful, compact Class D mono amplifier designed specifically to drive subwoofers with high power. With up to 750 watts RMS at 1 ohm, it delivers high output power while maintaining efficient energy consumption.

The modern Class D circuit with an Infineon® chipset delivers exceptionally high efficiency, thereby reducing the load on the vehicle's electrical system. The compact design, featuring high-quality die-cast aluminum side panels, allows for space-saving installation.

For custom bass tuning, the ZXR750/1E features an adjustable low-pass filter, a switchable subsonic filter, and an adjustable bass boost. A compact bass-level remote control allows you to conveniently adjust the subwoofer level from the driver's seat.

Thanks to its 1-ohm stability, the amplifier is suitable for a variety of subwoofer configurations. The built-in IFT technology for reducing electromagnetic interference, start-stop compatibility, and the blue-illuminated HiFonics logo round out the features.

The ZEUS POWER E amplifier series was named “Product of the Year 2025” by the trade magazine Car & Hifi.
