Odd Electrical Issue

Hey everyone.

So today, I decided to attempt to tackle an issue I've been having with my aftermarket stereo deck. Here's what's happening:

When my phone is plugged into the aux cable, everything is just fine, however, as soon as the charger gets plugged into the phone, you can hear the turn signal relays, engine rpm, etc through the speakers. Only when the charger and aux are plugged into the phone at the same time.

I replaced my ground lead from the negative terminal to the chassis today, and it's still there.

Any ideas? Thanks in advance!

Has it always acted like that since the aftermarket install?

This looks like it would help if you haven't seen it:

TL;DR of a TL;DR: "Check the stereo ground wire, and rewire/relocate it."

 

Also check the ground to the cigarette lighter plug you are using.

 

A filter cap on the power socket might cure the issue .

The charger is picking up the electrical pulses via the power socket

Are you using the lighter socket or one of the power sockets ??

 

Im using the lighter socket. Also, I can try moving the stereo ground somewhere else. I re-did the lighter socket wiring and the deck harness last month, as well.
