I installed a 1/2 din DVD player under the front passenger dash and got a bit of a problem. Connected the DVD player using an Add-a-Fuse on the line side and to the ground bolt on the neutral from the fuse panel on the front passenger side (Clock/Rear Light fuse space). The problem is that I now have noise on the audio side. When I accelerate the noise gets louder. I am currently looking in to Power Line Noise Filters. Any other ideas? Thanks.

P.S. Sorry for the spelling in the title.

 

You need to fix your ground to stop the loop. This will get rid of your "alt whine"

 

what are your suggestions on fixing the ground?

 

It always sucks but you need to troubleshoot and try to find a good ground. Or you can always try and make your current ground more solid.
