FWIW, with the new amps, the following power structure will apply:
XD1000/5v2's: one for each side (left and right): tweeter and mid bridged for 200w each. Woofer gets 400w. (14.4v spec)
XD400/4v2: rear fill. Bridged for now. 200w each. (14.4v spec)
The 12.5v input ratings bring it down to about 180w for tweeters, mids and rear fill and 360w for woofers.
