ESX SX-ONE

With the SIGNUM SX Mini series, ESX expands its extensive car audio portfolio with four brand-new MINI Class-D amplifiers that set new standards with their minimal dimensions, outstanding sound, and surprisingly high power output of up to 600 watts RMS. These compact powerhouses utilize state-of-the-art Class D technology, which, thanks to its high efficiency, enables low heat generation, thus making the exceptionally space-saving design—only 83 mm wide and 38 mm high—possible. This makes the mini amplifiers ideal for discreet installations, whether under the seat, in the side panel, or in the trunk. A particularly practical feature: The SX-FIVE, SX-TWO, and SX-ONE models come with a bass level remote control. This allows for convenient bass adjustment from the driver’s seat at any time—perfect for those who value flexibility and maximum control in everyday driving.   The SX-ONE is the top choice in our portfolio when it comes to driving subwoofers. This mini monoblock delivers enormous power, up to 600 watts RMS at 1 ohm, while remaining remarkably compact. State-of-the-art Class-D technology ensures efficient operation, stable power, and controlled deep bass.
