You have a problem with the phasing of your speakers. This will happen if on or more of the speakers are installed incorrectly. To solve this, you must check the speakers and find which one of them does not have the positive and negative connected to where it should be. When connecting speakers it is crucial that the speakers (positive and negative terminals) are all connected to the corresponding (positive and negative) speaker outputs of your head unit. Now you can enjoy your sound again.

In some installations it is not used.

Reply with your vehicle model/make/year and I can tell you the wire in the vehicle.

You can simply terminate the wire and it will be on full bright all the time.
It works in conjunction to dim with your dash lights at night. That is its sole purpose.
