The DD Audio SS4.500 car amplifier features 4 channels and a Class D circuit, delivering 125 W per channel at 2 Ω. Selectable high-pass and low-pass filters allow you to connect full-range speakers and subwoofers.
The heatsink has side walls that are 50% thicker than industry standards and elongated fins for increased cooling surface area. Key components include MOSFETs and higher-current outputs, higher-capacity capacitors, a stronger transformer, and a PCB with twice the thermal capacity.
