TPA3131D2: PBTL in 4ohm guidance

Hi,

My customer looks at getting a mono/PBTL >10W into 4ohms, and I do not see this reflected in the TPA3131D2 datasheet so please help me sort out any issues with this.

1) If they use PBTL setup like for TPA3110D2 (DS fig 46), what max PVCC can they apply to get below 1%THD in a single 4ohm speaker, and

2) How much continuous power will they be able to achieve before current limit, thermal protection e.t.c kicks-in?

Thanks!
