While dumpster diving I found a 2.1 speaker set. Static in the left

I swapped speakers, problem persisted.

in which speaker?

I swapped the op amp out with a
known good one, same thing.

I'm new to this kind of thing, so I'm a bit perplexed as what to try next.
It's not the source, I've tried several different sources. Wiring appears
to be okay. Sound to the subwoofer and the right speaker is okay.

Just short the audio out at the various points in the signal chain
(dont short power amp output tho). When shorting before a stage made
no difference & shorting after it killed crackling, you know where its
coming from. Prodding with a bit of plastic also helps locate if its a
dry joint.
