Ok here's the deal. Let's say I wanna power a 300Wrms 8ohms bass guitar speaker and a pair of 150Wrms 16ohms guitar speakers in parellel (so 300Wrms@8ohms if I'm not mistaken).
That's 2 channels at 300Wrms 8ohms each.
Now they say it's best to have a power amp that gives you double the Wrms of the speakers. So I would need a stereo power amp that gives me 600Wrms per channel, right?...
And that's exactly what the Crown CE 4000 does.

The Crown CE 4000 is priced at 1075$ and the CE 1000 is at 395$.
Link for the CE 1000: http://www.djdeals.com/crownCE1000.htm
The CE 1000 can operate in bridge mono and give me 900W @ 8-ohm.
So if I buy a pair of CE1000 and wire them both in bridged mono, I get 2 channels of 900W@8ohms for 2*395$. That's almost 300$ less than the CE4000 that's good for 2 channels of 600W@8ohms only.
If everything above is alright,
now here's my question:
Is there a "con" I fail to see or is getting a pair of CE1000 instead of a single CE4000 really a good idea? (rackspace isn't an issue in my case). Do I really get more power for less money or am I missing something?
Thanks in advance!

I don't understand when you say "they will each be running near the full output capability if used in bridged mono so you have less peak/headroom available."
Bridged mono would give me 900W available instead of only 600W in the other case. Doesn't 900W automatically give me more peak/headroom than 600W for the same speaker?
