ESX SX-TWO - 2-Channel Mini Digital Amplifier

SX-TWO
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 ultra-compact SX-TWO delivers an impressive total output of 2 x 140 or 250 watts RMS into 4 / 2 ohms with a very low total harmonic distortion of just 0.003%. Whether for powerful front speaker systems or bridged for subwoofers, this mini amplifier offers audiophile sound and powerful performance.
