Yes, this procedure should help isolate. I would do the LOC last.will hook up today, with just power/ground, and proceed to connect more, and see if i can isolate or reproduce.

K, so the Amp does not smoke with just power/ground connected. I unfortunately don't have a way to isolate the PnP harness from the LOC, as the one powers the other. I did think to change out the RCA's this time, to eliminate that variable, to no avail. With different RCAs from LOC to amp, and with LOC connected, but with speakers not yet connected to the amp (note, I did have the two channels connected from PnP harness to high input on LOC), I powered on the radio to reproduce smoke immediately. I could actually see orange flame through the cracks of the amp housing, to the far right in pic, behind the speaker terminals-Yes, this procedure should help isolate. I would do the LOC last.
So no speakers were connected at the time of initial startup or during this test?Should I repeat, with high input disconnected from LOC, from PnP harness? Would that make a difference, or help to further isolate issue, between LOC and harness?
Really appreciate the review and the input. I've put everything (paneling) back together for now, got pretty frustrated with it, but as soon as I have time, I'll pull everything back apart and check. I should have just grabbed a spare length of wire and checked harness continuity, end to end on all connections, with a meter while I had everything apart. I'm pretty convinced, at this point, that the harness has an issue, from the manufacturer - a wire mislanded, or maybe a short somewhere.Sounds to me like you have a 12v /hot wire connected to the speaker section on your pin harness. If it were a power issue /supply for powering the amplifier and not supplied and grounded properly, you should have blown an onboard fuse. Double check your Speaker connections at the Harness. You are frying the speaker section on the board of the amplifier. Thats my thinking/2 cents
Im pretty certain that having that much power12v/would also damage that LOC on the speaker section. It may be melted by this time hit twice with powerReally appreciate the review and the input.

If the above scenario is the case, with hot to speaker, would I have damaged the inline LOC, upstream of amp, in the process? Definitely want to eliminate all possible defects prior to a third attempt.
Thanks again!
I could be wrong, but it wouldnt take much to take the LOC apart and view the small board inside. It more than likely damaged though. Its like taking a plastic bag and throwing it into a fire.Im pretty certain that having that much power12v/would also damage that LOC on the speaker section.

Gotcha. Will try to open it up sometime this week and have a look. Would be one more clue to the puzzle.

Sure man. Id be interested in what you find/curiousGotcha. Will try to open it up sometime this week and have a look. Would be one more clue to the puzzle. Thanks again @audiobaun
