ESX SX-FIVE - 5-channel mini digital amplifier

SX-FIVE

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 use.
The SX-FIVE is the ideal all-in-one amplifier for complete car audio setups. With its exceptionally low-distortion four channels for front and rear systems, plus a separate subwoofer channel, the SX-FIVE allows for high-quality installations using just one amplifier. Despite its compact design, the SX-FIVE's 600 W RMS output provides more than enough power for dynamic sound and powerful bass.
