Using LLJ loopback harness have a question.

[DK91105]

I have tried to reach out to LLJ about this but as pretty much everyone knows they have abysmal customer service. 

 

I have installed a loopback harness that is supposed to take the output of all 6 factory speakers from my bose system (4 door speakers and 2 dash speakers) and run that output into a signal processor that will then feed those processed signals into 2 other amps.  

 

I have it all installed except I have not plugged the amps into the return side of the harness so I should not be getting ANY audio from any speakers. I have clipped the sub wires and am feeding them into the sound processor separately so I should truly not be hearing any audio.

 

When I started the truck to move it I am hearing audio from the passenger side front door speaker only.  Any ideas on why this is happening?

After messing with it more I saw that I was not getting any sub signal into my audio processor.  Knowing that I was not supposed to have any audio available to the front right speaker I unhooked the harness and started to just check continuity with my meter.  I found that the harness was wired incorrectly. The pass through for the sub signal and the front right speaker signal were pinned incorrectly in the harness. I de-pinned and changed the harness around and its fine now.

 

I would suggest for anyone getting a LLJ harness to just check all the connections with your meter prior to installing to be sure everything is going where its supposed to. It could save a lot of head scratching.

Not the first time I've heard of that happening with these guys unfortunately.
