ESX HXE750.5

The ESX HXE750.5 from the HORIZON series is a powerful 5-channel amplifier featuring classic Class A/B technology. It offers a well-thought-out combination of solid build quality, versatile settings, and impressive output power at an attractive price.

With its five channels, the HXE750.5 allows you to operate a complete car audio system—including front speakers, rear speakers, and a separate subwoofer—using just one amplifier. Each of the four speaker channels delivers up to 100 watts RMS at 2 ohms, while the built-in subwoofer channel delivers up to 350 watts RMS at 2 ohms.

Features include individually adjustable crossovers, an adjustable subsonic filter, a bass boost, and a wired bass level remote control. The high-quality aluminum enclosure, featuring acrylic glass inserts, a recessed diamond-cut logo, and sturdy mounting brackets, ensures an attractive appearance and reliable heat dissipation.

A MOSFET PWM power supply and a triple protection circuit round out the technical features. This makes the ESX HXE750.5 particularly well-suited for car audio systems where sound quality, performance, and easy installation are top priorities.
