DD Audio SX4.1000 Amplifier 4 channel class D

.

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.
