Thanks Perry! I use 4,7uF.
This card is working perfectly. Amp is Hifonics BXi4000D.
I have another card, but it's faulty.
Replaced two 21844, 311, 072 it's working but output is lower than normal and crackle it's sound.

I checked CL4, CL3, C11, and other side CL2, C4, CL1 and all resistors, and Q2-Q3-Q1-Q7 but everything is alright. Two 21844 is extreme heating.

Is the drive voltage low for both the high and low-side outputs of the ICs?
Don't let your probe slip if you're measuring at a point where pin spacing is tight.

The IC is rated for only 20v across the VB/VS terminals. 25v would be the minimum. I'd suggest using the highest voltage that will fit the pads.
