Can anyone help me try to figure out why I have no sound from my kicker amp even though the green light is solid. I have called kicker and they no longer provide schematics and I don't really know what to test. I have eliminated the board that contains the gain and all that by taking it out of a good 750.1 I also know it's not anything related to the wiring in the car as I hooked a different amp up in the same spot and it works. I know it's somewhere on the board but no tell tell burnt components.
 
Thank you for your time I do apologize as it appears my second post with what I have tested did no go through. I will try this again though. I checked all those before with good results I checked the preamp board with a 12v result it appears that the signal dies in a component under the preamp board but I am unsure of what to look for in that region.
 
I tested the LM361N chip today here are the results:
12.1 volts dc in
pin
1 12.06 V
2 0
3 -4.016 V
4 0
5 0
6 -12.01
7 0
8 3.288
9 3.288
10 0
11 3.268
12 -2.182
13 3.019
14 3.289

can anyone verify these as correct or is this the chip i need to replace?
