If it is one crash, like at the beginning (many seem to do that... ) you can highlight the waveform view of just the crash itself, then use the destructive PGMusic plugin, found under the Edit menu (NOT the DX realtime plugins), GainChange plugin, lower the volume of the thing by any negative number of dB desired.

You can do the same in Audacity using the "Amplify" plugin, but instead of turning the slider to the right to amplify the highlighted region, slide it to the left to "de-amplify". If the first pass is not enough, do it once again. In that fashion, you can eliminate it entirely if desired, provided that that only thing heard there is the crash and no other instruments, which is usually the case.
