you have to choose the woofer and then design your amp around it.

First find a cost effective woofer. Then build your enclosure. Then worry about the amplifier

Depends on what size woofer is suitable for your room. I use a 12" with mine, sounds awesome.

size is not the issue.

the impedance and the sensitivity is the issue.

My woofer is 12" 8 ohm with 95dB sensitivity. So it doesn't take much for that thing to get *very* loud.
