• (1) DD Audio 4-Ch Amplifier SX4.1000BT 

Cut the cord and crank the volume. The DD Audio SX4.1000BT is a next-generation 4-channel Class D amplifier built for extreme environments and simple, powerful installs. With integrated Bluetooth streaming and system control, this amp eliminates the need for a traditional head unit, making it the perfect solution for boats, UTVs, motorcycles, and off-road builds.

Delivering a full 1000 watts of system power, the SX4.1000BT is designed to push through wind, engine noise, and open-air conditions with ease. Run it as a 4-channel setup for mids and highs, bridge it into a 2-channel powerhouse, or configure it as a 3-channel system to drive speakers and a subwoofer simultaneously.

Built to survive where others fail, the SX Series features an IPX67 waterproof rating, protecting against dust, water, and harsh outdoor environments. The rugged aluminum chassis, cast end panels, and sealed controls with protective plexi covers ensure long-term durability in marine and powersports applications.

Internally, this amp is upgraded with higher current MOSFETs, increased power capacitors, a more powerful transformer, and an enhanced PCB with improved thermal capacity. The result is stronger output, cleaner sound, and better reliability under heavy load.

Whether you're building a no-headunit system or expanding a multi-amp setup, the SX4.1000BT delivers serious performance in a compact, adventure-ready design.
