Default 6-channel amp

I need advise.

For a small room I need a cinema power amp, about 30-50 watt
per channel (in one case) to drive:

- Surround L og R
- Center
- Sub L og R

Front L og R are driven by my normal 2-channel power amp. Pre-amp is multichannel with built-in processor.

The way I see it, it will be six channels. Three
stereo amps where one of them is bridged to be used for the center speaker...

How do I proceed? I was thinking of a simple (and not too expensive) class A/B amplifier.
With three power supplies, one for each stereo amp. This will also make it easier for me to build I guess, cause I'm not too stiff in electronics.

Anyone can recommend simple two-channels A/B
power amp circuits to be build in one case, about 45 *
35 * 13 cm?

The reason for having L and R channels for sub amp is that I plan to have small passive subwoofers in both L and R channels (I am building L & R front loudspeakers which will have room for a woofer in the bottom).

The existing L and R power amp is Audio 60 (Doxa) class AB 2*60 watts.
