Close....clipping allows the amp to produce 2x it rated power, if the sub is a 500w sub, and you send it 250w from an amp that is fully clipped, it will be fine.
A speaker will play any signal you provide without hesitation regardless of whether it is distortion, a sine wave, a square wave, etc. As long as you sub can handle the power, there will not be an issue.
