its easy to test, sit in your drivers seat and setup the same song on your car and on your phone, put in a pair of headphones close your eyes and listen to some music then play the same music on the car stereo and see if the sounds come from the same places.
When I did that against a 4AWG jumper cable clamped to the neg battery post I got 0.3 ohms but I got this weird amp heating even though the amp was not even driven yet. That make no sense to me, but when we ran a 0AWG cable from the neg battery post to the amp dist block the heating problem ameliorated. And you can't effectively argue against evidence.
I don't have a "phone".
Silicon spray? Not a bad idea on my ground. Nice thread by the way //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif
Normally it's called.....PAINT //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif
Imaging with headphones isn't as much of a phenomenon as it's mainly restricted to mono sounds in the center, and panned left and right sounds are distinctly left and right, without any reflections. It's the lack of reflections from a "room" that makes headphones less interesting in terms of imaging and staging than sitting equidistant between two speakers or sitting in a well-tuned single seat SQ vehicle. There can't be any stage depth with normal headphones.
So your saying non-source included reflections and cancellations create interest and depth that makes imaging better? Seems counter intuitive and illogical to me.
Yes. I'm getting back into reading 'Sound Reproduction: Loudspeakers and Rooms' by Floyd Toole. It's a must-own book on this subject that I bought a couple of years ago and didn't finish.
I COULD have done many gnd points, but figured it was the best place to get a gnd. I already had a 0AWG cable to the pos battery terminal, I figured a 0AWG to the neg battery post would be perfectly impedance balanced up to the battery + and -.
