Rockford Prime 1000.1D - identifying smd caps

Highly doubt it, i will change it but even with no input from the pre amp, there should be switching in the class D, the PWM is not generated there. Pre amp only carries the analog signal. Even if you remove the cap entirely we are just decoupling the pre amp from the class D, nothing else.

At NE5532 pin 6 there is also -->10k resistor --> Zener -->100k resistor --> GND not sure what is this all about. I still don't think the voltages at NE5532 are correct.
 
Does that correct the biasing issue and allow pulses to be produced from both IC? = no, it does not.

But if you try to start the amplifier while having a load hooked up, it won't. It will go into protect.
Adding a dummy load while the amp is already running does not make it go into protect.
