Ground loop

[daddy]

Shorten the ground for the head unit. It's an antenna for noise. move the head unit ground to a location closer to the head.

I've had the noise with it grounded two different ways. My guess is it's not the ground.

Thanks though!

What 2 differernt ways?

One with the amp, the other factory. I realize that's not the same but the odds are against the ground issue. I'll try it after I try a few other things.

Humor me. Since the head also grounds through the antenna coax, disconnect the ground wire in the heads harness and see if the noise goes away.

I have had this happen with a bad ground off of the battery.

Hope you get it figured out T!


Mines even weird-er. It seems that when my amp hits 117* (digital readout on the amp), the front right speaker starts crackling. I don't remember exactly what all I tested, but I'll be back at it once the weather warms up. I was told to move the ground of the amp so I'll try it. I took the truck to an audio shop and they said they've heard it once or twice before, but still couldn't really explain it. I sent the amp to Kenwood (who ran it at 130*+ continually) and they had no problems. I did read that there might be think happening with my HU, so I'm gonna replace it (I wanted to anyways).

If you have an amp for your 4 channels, see if you can disable the internal power of your head unit.

I have 4 pre-amp outputs going to the amp.
