Host dsp power amplifier, need to add power amplifier?

Most of the power amplifiers provided by the host or DSP are relatively low in power, generally below 50W, with general heat dissipation capacity and thin power lines, especially lossless lines. Some machines only use 1 square copper wire, so the power supply capacity is not enough. Pushing the original car horn or low-power horn is barely enough. For players who have requirements or pursuits for sound quality and have a high budget, it is recommended to add another power amplifier.
