Ok this may seem like a caraudio question but its more about current and impedence. I've got an amp with rca input, i want to however run both my carpc and my headunit. I tried a AV switch but i got alot of noise and background junk when both where connected. So i'm considering just using a "Y" splitter on the rca in and just plugging in both inputs directly into it. I found this on another forum : Is what this guy saying is true ? i.e. it shouldnt damage any of my equipment doing this ? What i'm worried about is say I turn my headunit to mute, since its not outputing a signal, will the carpc's signal travel up to the headunit and damage it ? or vice versa ?
