Depends. What are you driving? The numbers you offer are only what the amps are supposedly capable of doing under test, not what you will get from them under normal conditions. Think about this: if you bi-amp, do you really think most tweeters can handle 100w, let alone 200?

watts per channel when biamping

I am going to purchase a second amp and biamp. I now have 100 watts per channel at 8 ohms and 200 watts at 4 ohms. The way i understand it it will be 200 watts when biamped. If the other amp is 100 watt at 8 ohms and 200 watts at 4 ohms, will I actually now be going to 400 watts since it is 200 watts for both amps at 4 ohms or will it be 200 watts. Thanks for any help.
