Don't worry about your 300wpc amp powering your 100wpc speakers. You do not have to match the numbers. As stated above, it is much more likely to overdrive a low powered amp to clipping and damage a tweeter. You will hear the strain when over driving your speakers with clean power, so back off when they sound like they might explode!
By the way, an amp has to malfunction to "send DC" to your speaker. That is not what "clipping" is.
