Wiring dilemma for Dynaudio 220MKII - Suggestions?

Question

Got a set of 220MKII's and a PPI PC450 amp (4 X 50W RMS).  I'm wondering if I should use one channel per speaker (2 mids and 2 tweets) and cross them actively (I have the processor with the ability to do so), which would result in 200 totals watts (100W to each side) or bridge the amp and run 400W (200W to each side) using the passive crossovers coming with the set. I know these speakers are reputed to be power hungry... any suggestions? Anyone have a similar experience / decision?
