ESX HXA100.2

The ESX HORIZON HXA100.2 is a classic 2-channel Class A/B power amplifier that provides reliable amplification for front and rear speakers as well as for a subwoofer. With an output power of 2 x 70 watts RMS at 4 ohms or 2 x 110 watts RMS at 2 ohms, it offers sufficient power reserves for a variety of car audio applications.

The HXA100.2 is also ideally suited for subwoofer use. In bridged mode, the amplifier delivers 220 watts RMS into 4 ohms. Using the built-in high-pass and low-pass filters, the bandpass function, and the adjustable bass boost, you can tailor the sound to the connected speaker system.

Features include a MOSFET PWM power supply, heavy-duty connection terminals, and a triple protection circuit. The aluminum heat sink with acrylic inserts and an embedded diamond-cut logo gives it a high-quality look. A compact bass-level remote control is also included, allowing for convenient adjustment of the bass level from the driver’s seat.
