With the SIGNUM SXT power amplifiers, ESX opens a new chapter in mobile amplifier technology. Designed specifically for trucks with 24V electrical systems, these German-engineered amplifiers offer outstanding sound, massive power, and maximum reliability – exactly what you need for everyday use on the road. The one-piece die-cast aluminum heat sinks ensure optimal heat dissipation and provide a sophisticated look. Combined with modern Class D technology, the ESX amps are compact, highly efficient, and incredibly powerful. Perfect for anyone who demands top-notch sound, even in a truck.
The SXT1200.1 is the top choice for uncompromising 24V bass performance in trucks. All relevant filters and crossovers are integrated, and a bass level remote is included as standard. This compact monoblock delivers a solid 900 watts RMS at 2 ohms and an even more powerful 1,200 watts RMS at 1 ohm – remarkable considering its compact design. In the Car&Hifi test (issue 1/2026), the ESX amplifier performed even better: a remarkable 1,374 watts RMS were measured at 1 ohm. This further demonstrates how conservatively ESX calculates its power ratings. For this outstanding performance, the amplifier not only received the POWER TIP but also the highest possible rating of 1+.
