ESX SXT900.4 (24V) 4-channel class D digital amplifier

With the SIGNUM SXT power amplifiers, ESX opens a new chapter in mobile amplifier technology. Specifically designed for trucks with 24 V electrical systems, these German-engineered amplifiers deliver exceptional sound, extraordinary power, and maximum reliability: exactly what you need for daily road use. The solid one-piece die-cast aluminum heat sinks ensure optimal heat dissipation and give a sophisticated look. Thanks to modern Class D technology, ESX amplifiers are compact, highly efficient, and incredibly powerful. Perfect for anyone demanding the highest level of sound, even in a truck.

The new SXT900.4 impresses with maximum flexibility on board the truck: with up to 4 x 225 watts RMS, it powers front and rear systems powerfully and reliably. In mixed 3-channel operation, it delivers 2 x 225 watts RMS plus, in bridge configuration, 1 x 450 watts RMS for a subwoofer. The included bass remote control allows convenient level adjustment from the driver's seat. Variable high-pass and low-pass filters from 50 to 5000 Hz offer maximum adjustment freedom. In the Car&Hifi test (1/2026), the ESX amplifier impressively demonstrated its class: with a power output of 4 x 257 watts, very low distortion, and a signal-to-noise ratio of 98 dB, it significantly exceeded ESX's factory specifications. Editorial rating: Superior class, value for money - excellent.
