TPA3116D2做成单声道模式保护

我用TPA3116D2做成单声道模式，SDZ和FAULTZ接在一起，量电压为0V，把输出的LC滤波电路的电1uF开路，SDZ电压为20V。电源电压23.7V。把与SDZ的限流电阻100K改成10K电压为23.7V，增益36dB   请问怎么会保护。图片是不接电感的波形

The TPA31xxD2 family can be connected in MONO mode enabling up to 100W output power. This is done by:
• Connect INPL and INNL directly to Ground (without capacitors) this sets the device in Mono mode during power up.
• Connect OUTPR and OUTNR together for the positive speaker terminal and OUTNL and OUTPL together for the negative pin.
• Analog input signal is applied to INPR and INNR.

保护问题找到原因了，是输出的电容220nF有问题，换了就可以了，是元件质量问题，但是还有个问题，接上LC发热很厉害，输出功率没有不接LC的大。电感是uH,电容是1uF.

还有音量开大了，低频好像咔咔的响，不是那种破音的效果，
