I keep the volume on my poweramp on full and adjust Monique to taste.
I generally don't bridge (never with one 210 cab) as one channel on the Crest is almost 1000W. If I play an outdoor gig and need lots of stage volume (and use 2 x 210 cabs), I might run in bridge mode.
The crest prolite 2.0 is no where near 1000w on one channel. Do you have a different model?
Here are the specs on the 2.0
8 Ohm Bridged - 1160 W
4 Ohm Bridged - 2000 W
2 Ohm Stereo - 980 W (2 x 2 ohms)
4 Ohm Stereo - 540 W (2 x 4 ohms)
8 Ohm Stereo - 300 W (2 x 8 ohms)
2 Ohm Stereo - 1050 W (1 x 2 ohms)
4 Ohm Stereo - 600 W (1 x 4 ohms)
8 Ohm Stereo - 290 W (1 x 8 ohms)
