The DD Audio SS4.500 car amplifier has 4 channels and operates in Class D. It delivers 75 W per channel at 4 Ω and 125 W per channel at 2 Ω. Selectable high-pass and low-pass filters allow you to connect full-range speakers and subwoofers.
The aluminum heatsink has side walls that are 50% thicker than industry standards and long fins for increased cooling surface area. Upgraded components include MOSFETs, higher-current output devices, higher-capacity capacitors, and a more powerful transformer. Enhanced ventilation and the PCB’s doubled thermal capacity further support operation.
