I've got an 05 Altima that had some work done to it.
First, 2x 12" subwoofers were installed along with a Alpine CDE-102BT stereo..everything was relatively ok. no real radio interference
then, windows were tinted, 8k HIDs were installed, and a new head unit (Kenwood DNX6160) was installed.
The radio interference is insane..position is completely irrelevant cause it just sounds like static/faded/muddy no matter where you are.
I can't really get in contact with the people who did the work so I have to solve this problem on my own. I read somewhere that the HIDs power wires can interfere with radio signal if that same wire is near it but my knowledge is limited of car audio.
I am not exactly sure what to look for or what is the right/wrong setup as far as this kind of installation goes so I am more than happy to take pictures of anything that would help
here are a few,
this is bottom left by the steering wheel. pretty sure it is a power wire coming from the battery that leads to the amp behind the rear seats
I am pretty sure this is the GPS satellite for the head unit. It sits right underneath the glass on the dash. I don't know if modern technology has combined the GPS/Radio satellite into one or if the radio one is somewhere else
This is the other side of the car by the seats. Appears to be a black cable
Thanks again! any help is appreciated
