Do the surrounds really need much power

I'm in the process of upgrading amps and wondering if the surround channels really need as much power as the mains and center? There isn't as much information going back there and the speakers are smaller. It seems logical that less power is really needed.
It depends on what surround format your using. Dolby Pro Logic doesn't send much info to the surrounds and the surrounds are also bandwidth limited. Dolby Digital, DTS, etc... all have full bandwidth to every speaker with a greater amount of info also. Plan ahead and get what you need now so that you won't be going through this again in a few months. Sean
See my post on the other thread you started Robedk for my experience.
