Compresion problem

i now know its not my speaker cables, but my compression unit. when i use my head, it blinks normally, but after 20 minutes, it goes from blinking dim, to staing solid as bright as possible, then the amp makes a break up, walkie talkie like noise. this just doesnt go for high volumes, all volumes will do it. even when i dhut the compression off, it still does it.

I NEED HELP!

 

sorry bout the spelling. i need to clear my head, very stressed out. I call my symptoms, Crappy-rouge-amp-itis.
