Hi.
I just got my new frontstage setup:
CDT ES-04 mid, ES-07 woofer, DRT-26 tweeter, ES/HD-300 x-over and UP-526XT UpStage kit
I'm not sure how much rms it requires.
My amp PPI PC4100 4x100w or 2x400w.
Any Suggestions?
Thanks.

 

Unles you have an equalizer piece (like a AC EQL) I would go with the 4 channel set-up to give gain control on the E.7. Bridging the two sides will give lots of power but often the mid-high range is too loud as compared to the mid-bass drivers because the midbass drivers (usually) need more power to have the low-end frequencies remain flat with the higher frequencies.

BTW - I think that amp will put out 2 x 800 bridged.
