Hey all,
I'm having some audio trouble within my car. I have a 2015 Lexus CT200H. I will list the exact equipment below. I am having a horrible hissing/static/white noise type of sound coming through my speakers. I can't figure out why it's happening. It also doesn't happen all the time. It's intermittent. I also can't figure out what aggravates the noise or influences it to change in any way. The noise does completely go away when I shut off the radio (obviously). The sound noise IS present with music, Bluetooth phone calls, etc. I am posting a video clip to this thread so you all can hear it for yourself. I'm also attaching how my system was wired in a diagram form.
One thing that is worth mentioning is the 5 Channel Amp is under the driver side seat. The MiniDSP and its power source brick is laying on top of it. The MiniDSP is also wired directly to the remote turn on wire coming directly off of the amp (it was a quick fix to a problem that was present at the time), I know it's kinda wrong).
If anyone has suggestions on what to do, I'd seriously appreciate it. This noise is killing me so badly!
