Hello
I am looking for help or suggestions to try to resolve a fault.
The amplifier is a kicker kx 700.5 and the fault symptom is lack of power in the 5 audio outputs.
Check the muting stage, it seems that is not the problem.

Is the rail voltage steady for all channels?
What is the rail voltage for the 4 full range channels?
Rail voltage for the sub channel?
At what ACV do the 4 full range channels clip?
ACV for the sub channel at clipping?
Check the above two ACVs with and without a load.

yes
+/- 29.72v
+/- 53.33v
1.98 ACV With load 4 ohm each channel . tone 60hz channel amp 1 L
2.01 ACV With load 4 ohm each channel . tone 60hz channel amp 1 R
0.54 ACV With load 4 ohm each channel . tone 60hz channel amp 2 L
2.24 ACV With load 4 ohm each channel . tone 60hz channel amp 2 R
1.48 ACV Without load 4 ohm each channel . tone 60hz channel amp 1 L
2.05 ACV Without load 4 ohm each channel . tone 60hz channel amp 1 R
0.34 ACV Without load 4 ohm each channel . tone 60hz channel amp 2 L
2.46 ACV Without load 4 ohm each channel . tone 60hz channel amp 2 R
0.839 ACV With load 2 ohm tone 60hz
1.01 ACV without load
I have signal problems on channel amp 2 L
I will check the gain adjustment potentiometer
I HAVE CHANGED C657, in that channel the audio output improved a lot.
I will change the other associated capacitors.
Thank you very much for the schematic and your time of help
