When operating a 200W subwoofer with only 100W, there will be a loss of performance in terms of maximum volume output and bass response. The subwoofer will not be able to reach its full potential in terms of power handling and may distort or clip at higher volumes. Additionally, the overall sound quality may be compromised as the subwoofer will not be able to reproduce low frequencies as accurately or with as much impact as it would with the full 200W of power. **
