That's generally how it's done these days. If you've got two 200W RMS cones, I would recommend finding a four to five hundred watt monoblock amplifier. Decent ones will cost you a couple hundred bucks.

And yes, two SVC 4 ohm speakers in parallel will render a 2 ohm load, so you're safe on just about any monoblock I've ever seen. Most of the big ones need to run at 1 ohm to get true power these days.

Something like a Directed D600 would probably be perfect for you. 300 watts @ 2 ohms, and the price tag is below $200.

The other option is to get a normal two channel amplifier that runs about 200 watts @ 4 ohms bridged, and run it at 2 ohms instead. I don't recommend doing this unless you can pay attention to the amplifier for the first couple of weeks. Most aren't built to run at that load in that configuration. But a lot of newer amps will do it if you can keep them from overheating. I've been running my two channel Eclipse at 2 ohms since the day I bought it almost two years ago. Haven't had a problem yet.

Just make sure you understand the difference between loud and stupid.
