Hi guys. I've been using my ti600.2 for around 5 years now and love it. For the last 3 months I have been getting a extremely loud skreech come through my components after moderate/heavy useage. If they are played at low volumes nothing seems to happen.
This happens only when I turn off the ignition and does not happen when I turn of the head unit.
Do these units have some sort of turn off circuitry? I have checked my remote wire and power/ground cables and all is well there. Its just so loud that I am getting worried.
