Hey, I picked up a Korean cab recently and for the life of me, I can't get one channel of audio to have correct volume. Right speaker, right sub both will have correct volume levels while the left speaker and left sub will have very faint audio. If I swap the RCA cables inside the amp (white to red, red to white) I can switch the side that's faint.

I'm not sure what to do besides buying a new amp entirely.

I checked the audio coming out of the 573, both channels are fine. I checked the boards inside the amp and they didn't seem like they had any issues. I gave them a once over and didn't see any cracked solder joints. I checked the RCA cable going from the 573 to the amp and it's fine. I assume if it was a wiring issue, I would still have issues on the left speaker/sub when swapping the RCA cables.
Any help would be appreciated.

Do you still get the same problems if you fed the amp music from another device? e.g. laptop?
Any caps popped in the amp?
