The SX4.1000 produces an impressive 250 Watts across its 4 channels, contained within a mere 32 square inches. This amplifier can be wired to deliver a robust 2×250 watts output to the mids and highs and an additional 500 watts dedicated to the low-end of a subwoofer. The SX4.1000 is the ultimate solution for any rugged duty system design.

The SX amplifiers are IPX67 waterproof-rated designs with higher output levels tailored for environments with elevated noise levels. Their increased output power and enhanced fortitude is achieved through the integration of cast aluminum end panels, aluminum bottom panels and preamp controls with protective plexi covers.

These amps use premium components sourced from world renown brands for a transformation that is not only tangible, but audibly unequivocal. These include higher current MOSFETs and output devices, increased power capacitors, a more powerful transformer, plus improved venting and PCB with twice the thermal capability. State of the art upgrades like these, combined with DD AUDIO’s uncompromised high speed, class D design and industry defying heat sink, all result in a high-end mini amp with more power and better sound quality with an incredibly compact footprint.
