TPA3255 MONO. True power output? Good power supply for these?

[777funk]

I've been using a TPA3118 for various things around the house and have decided I'd lke to put in a sub. Is the 3155 a good choice for a cheap easy class D amp? Is there a good switch mode power supply that can be found to run this thing?

I am going to bump this as I would like to know also

The continuous max power under 120Hz is about 220W/BTL channel.
In Mono PBTL Configuration it should be about 440W.
See section 11.4.2 Thermal Performance with Continuous Output Power, from the datasheet.
In the next section is described for music with different compretion ratios.
