Evaluating subwoofer power

The user is asking whether a 50W-rated subwoofer exceeds its limit if connected to a mobile phone with both volumes maximized.

Essentially, the subwoofer is designed to handle a max of 50W input power. Even if both the mobile phone's volume and the subwoofer's volume are on full, the power delivered shouldn't go beyond 50W because subwoofers are typically structured to handle up to that amount of power.

So, no, the 50W rating should still be respected.

Clarifying power limits

The subwoofer's 50W rating is the maximum power it can handle, but the actual power delivered depends on the mobile phone’s amplifier. Typically, mobile phones output much less than 50W, so the power won’t exceed this limit. Even if both volumes are turned up, the phone’s amplifier will likely cap the output. In general, portable devices can’t output 50W due to battery constraints, so it's highly unlikely the subwoofer will receive that much power.
