Ask Boston Acoustics for a minimum recommendation, they're their speakers.

The SC50's are rated at 65watts RMS so you should have an amp that can provide at least 50 watts/ch.
I'm using a JL Audio xd400/4 (think that's the right model #) which is 100w/ch into 2 ohm speakers. The SC50's are 4 ohms so the amp can only deliver ~75w/ch if you drive it to the max.
