Amp wiring question 2008 Ford edge

[lwalters71203@gmail.com]

Some one put a new factory amp in our 2008 edge. I am trying to find out if the silver bare wire connects to any of the wires on the amp plug?

All the wires are connected but that silver wire. I am getting no sound unless the plug is moved and getting popping sound

There should be no bare wires anywhere in your car. The silver color is a tin coating over the copper.

 

It may be best to rip out whatever wiring is there (sounds like a micky mouse install) and install a known wiring harness.

lwalters,

 

The bare silver wire is most likely a shield (drain) wire. It will be connected (grounded) at one end or another, but never at both ends. Normal wiring practice dictates that it is attached to the case ground of the upstream device. Simply, it shields an audio channel (or any other analog signal) from interference.

 

I've attached the wiring diagrams for the audio systems pertinent to your model year (and mine) for your use. There are many variants. You'll notice the shield wire and where it is connected doesn't always follow convention.

 

It seems that in your situation there may be a loose connection somewhere. Check your shields. Personally, I like solder and heat shrink for audio connections.

 

Happy trails.
