What is amp's watts-per-channel exceeds speaker?

I want to buy an Outlaw Audio 950 pre/pro along with their Model 770 7-channel Amplifier. The amp puts out 200Wpc.

I have YET to buy speakers, and I have only $1,000 above the pre/amp to buy speakers. I planned on using all $1k for a decent pair of fronts, and try to use my existing 5.1 speakers (these were on a Sony receiver) to fill in the other holes in this new 7.1 system.

My proposed speaker setup:

Fronts: Not yet decided
Rears: Celestion Impact 30, 4 ohm, max 150W
2nd Surrounds: Celestion "Little 1", 8 ohm, 10-50W
Center: MB Quart Center, 6 ohm, 125W
Sub: Velodyne self powered 10"

Here's my newbie question: What happens to my existing speakers when I drive them with a 200Wpc amp? Does the amp step down automatically? From the pre/pro, can I tell them amp to step down the wattage?

Thanks, Greg

All of the above is correct. However it is worth mentioning that if you keep raising the volume beyond what the speakers can support you WILL damage the speakers!
Don't worry though, you will clearly hear the speakers reaching their limits well before you can damage them.

Of course all of the above statements are correct and yes the wattage is turned down by the volume control. You won't be sending 200 watts to the speakers unless you turn it up all of the way.

i'm running 2x100 (aka 200W) bi-amped power to my CDM1-NTs. they're rated at 8ohm/120W but handle playing as loud as my tastes require (and quite a bit louder i assure you) and will do so for years, reliabily... it's just the nature of speaker companies to rate speakers in such away, because some knob would complain / sue / whatever if they put 400W thru an 80W speaker at full gain (and while clipping an mp3 at 64kbps recorded off a scratched CD using a laptop driving on a back country road, no doubt. probably the same sot who'd sue McDonalds because they spilled their coffee on the laptop).

cliff notes: don't worry, it'll work BETTER that way actually.
