Amp help

Hey all,
Im new to this fourm. I've got a 89' F-150 Standard Cab so of course, I have limited space. Ive got my system that i wanted picked out and narrowed down pretty good now.

Pioneer 5600 Series 50WT 4-Channel Sterio
2 Custom made boxes
4 10" Kicker CVR
1600wt. 4-Channel Phoenix Digital Amp
Pioneer Door Speakers
Infinity Tweeters
Phoenix Digital 1.5 Fadar Capasitor

Now the question. I talked to the Kicker guy and he said that the 10" CVRs are 400wt. Now me having a 4-Channel 1600WT works pretty good. But there is a problem. 4 Channel @ 1600WT would mean 400WT each Channel, but what does this mean?

125W X 4CH @ 2 OHM = 500W
100W X 4CH @ 4 OHM = 400W
250W X 2 CH BRIDGED

Am I right at each channel having 400WTs?

Any info appreciated,
Ethan
