As it says I am getting feedback in my stereo in my truck. I have a small speaker box with an amp behind the seat and I think it is all coming through there, but when I turn on the blinker, windshield wipers, or step on the brakes, I can hear a pop in the speakers. Bad ground? Something else I should look for? I really don't know all that much about this stuff as you can tell.

Thanks!

 

Could be bad RCAs also, are they new wires, or have they been used before? Your ground should be grounded under the carpet to the body for best results. Make sure no wires are bare and touching, etc etc.

 

sounds like a ground issue to me. run your stereo and amp thru a dedicated ground to battery.

You might also try a 1F cap if your pushing alot of power.
