Need some help. R53 03 my stereo stopped outputting sound. I have full power to the stereo checked fuse 10 and 27 all good. I’m thinking it’s the AMP. I checked P5 on the Amp harness and getting power. Is there anything else I can do or check to make sure it is the Amp? Is there a way to bypass the Amp so I know 100% that that’s what it is before I purchase a replacement.

 

h/k amp, i would just swap a used one in to test.
