Howdy. My electronics instructor said that turning a head unit on, with nothing connected to the speakers, can instantly fry the internal amplifier, etc. Is that true? I think he mentioned that the internal chip must see 8 ohms produced by the speakers (it might have been 4, I can't remember) and if it doesn't it'll fry.
I ask because when I got my AVH-P6400 I bench tested it for a minute or so, with just the 3 power related wires connected. I installed it and has worked fine for months. And, what if I wanted to use strictly pre outs to send the audio out to an amplifier and then to the speakers? Do you have to do something to the head unit speaker wires or just let them hang there (more or less)? Is there an internal "switcher"? Thanks.
