I have run into a strange problem . I am running a three TAS5825 system with 2 stereo and 1 subwoofer channel PBTL . The schematic is copied from the the data sheet with 10uh inductors
The left/right channels can outputs( stereo amp can easy produce 26 watts into a 4ohm load. However, the subwoofer amp quits at anything above 20 watts ( 80 hz).
I am not getting error codes from the fault or warning registers. The 0x68 register indicated sleep mode.
I am baffled , because the same circuit cranked out almost 50 watts with an almost identical layout.
I am looking for any hints on what to look at.
