 Amp RMS = sub RMS?

Hey, I have this Pioneer TS-W309S4 4ohm subwoofer, which runs at 400w RMS. I heard somewhere, that i would want to have an amplifier which also runs 400w RMS to get the best out of my sub, so if i get an amp that's say - 200w RMS, my sub would only perform at that RMS?

Idealy I like to have an amp a bit more than the rms of the driver. That allows you to keep the gain a little lower and less strain on the amp. You also use the cleanest part of the amp. However....Using 200 watts on a 400 watt driver is fine. As long as you don't crave to get it louder and crank the gain until it clips.
