I need some help here. I was doing this mod here to my stock head unit:
Well, I got to the part about removing the resistors, and on the very first try, I messed up my resistor. So, off to Radioshack I went, hoping I could replace them. I got two packs of resistors, one pack was 1 watt 10 ohm, and the other pack was 1 watt 100 ohm. Well, I continued the mod, using the 10 ohm resistors. Plugged everything back into the truck, and there was this screeching noise coming through my speakers. I can hear the radio playing faintly, and when I plug my iPod up, it will override the radio, and I can faintly hear it. The whole time, this quiet screech is accompanying the music.
So I decided to take it apart, and try the 100 ohm resistors. Replaced them, put the radio in the truck, and the quiet screech is still there. This led me to believe that it isn't the resistors that are causing the problem. Because with both of the different resistors, the same thing happened.
Can someone help me out here, and give me some insight into what is causing this screech? It isn't that "nails on a chalkboard" screech, it's more like a constant ring-type of screech.
Any input, positive input is welcome!
