When I downloaded TPA3130 datasheet, I saw power figures of 2x50 W, and thought "wow, that's some serious margin there". And even published it here. Today I suddenly realized while re-reading the datasheet, that the datasheet is a shared one for 3 ICs: TPA3116, TPA3118 and TPA3130. The difference between them is their power rating (specifically, overload current limit).
The actual IC used here is only for 2x15 W.
