Loud buzzing from wire interference behind headunit. Can't find a solution

[RageQuitForLife]

So a month or so back i posted about a loud buzzing that came through my speakers. I have figured out that it is coming from some wire behind my headunit but cant figure out which one it is or how to fix it.

I would pull the headunit out with the car running and after pulling it out of the slot the buzz would go away and depending on where I moved it the buzzing would be more or less.

It seems that one of the wires is getting interference from some piece of metal behind the headunit slot, but I don't know which wire or which piece of metal is causing it.

Should I just try to rap all the wires behind the headunit in something to try and stop it?

Does anyone have any insight on what I need to do to get the buzzing to go away forever?

first, check that all connections on the head unit are clean and secure. it sounds like you have a loose connection

[RageQuitForLife]

everything on the headunit is fine, the aftermarket headunit has all crimped connections from the stock headunit.

Check the RCAs and make sure that the shield connector on the head unit is connected to the chassis of the radio with a meter. Some head units have an internal fuse.

Model of deck might help. Non shielded or crap RCAs? Are the speaks amped? How many and what brand of RCA's? Where is the humming coming from exactly?

What do you mean have it connected to the radio chassis with a meter?

[ShadeTreeMechanic]

The RCA sheild should be connected internally to the head unit ground. What type of head unit? We need more information on your system.

I am assuming you are running an amp.

Sounds like one of your connectors has a some wire sticking out of it contacting the chassis of the h/u when it is installed causing the issue.

I quit using butt connectors long ago, and now will only solder and shrink tube the wire to remove any possibility of something causing a problem later on down the road, and another thing about those ugly ass connectors are the massive amounts of space they take up.
