85 GMC Sierra "Scarlett"

[N2TRUX]

I ran in to an issue as I was bringing to Kicker Audio install to completion. After our last tuning session on Scarlett, we pushed her back in to her storage spot. We had the key on and heard a weird rumble coming from the Hideaway sub. I researched the issue, but no luck. It would play fine then this deep rumble would come in. This is frustrating.

I contacted Tim Smith from Kicker. He suggested checking my ground. I ran an additional ground wire direct from the frame, but this wasn't the problem. Tim put me in contact with his coworker Jerimy for a more in-depth analysis. Jerimy suggested unplugging the remote gain control. I unplugged it and the rumble stopped. Great, this should be a simple fix.

Last night I chased the trouble and thought I had resolved it. The input to the controller gain uses a mini RCA that appeared to have come partially unplugged while securing all the wires under the dash. I pulled the controller and added a strain relief to the wire to prevent this from happening again. Problem solved, I thought but the super short screws used to mount the controller were now stripped. This lead to a search for new screws and an hour long ordeal in changing my mount design.

I tested the system and breathed a deep sigh of relief. I had solved the problem and now I could put everything back together. I left the system on while I replaced all the cover panels. When I got to the point of securing the Hideaway sub, the rumble came back. What now?
