Default Chipamp with crossover question

Hi All - i'm building a pair of active speakers using chipamps. I want to use 3x LM3886 for the woofer (PA150 board) and a single LM3886 for each mid and tweeter. I also want to incorporate the crossover and house the whole thing in a compartment in the bottom of the speaker box. My question is do i power the supply board for the crossover ( Rod Elliott P05) direactly from the transformer or do I come in after the bridge rectifier using DC from the supply for the chipamps? If so would I need lesser value smoothing caps on the board? (currently 2x 2200). Any other problems I might face?
Thanks for your help.
