The reason i shared/posted the video was that i was personally unaware that on amplifiers there 'could' be one of two styles of RCA connections; A 'single Ended' or 'differential Input' and each are more suited to a certain style of RCA: Twisted or Center core. Again this was new information which kind of blew my mind. I really like how he suggested one would check to see which style RCA signal input you amp has "...Take an ohm meter (DMM) and check the resistance from the battery ground connection on amplifier to the RCA outer ring on amplifier (with everything unplugged from amplifier). If you have less than 100 ohms it is a single-ended input..." For me, it was real light bulb type moment when i realized why some RCA's are comprised of twisted pairs, for once this was not just a marketing concept to me.
I'm definitely not trying to make this an 'Exotic' vs xxxx brand Cable thing, as im sure most would just roll their eyes at that type of discussion/post (including myself).
And after thinking about this today while working on my install i started to wonder how much this even matters. What if the Head unit has one style of RCA Circuit and the Amplifier an other? and then what about pieces in between the source and the amp like a DSP?
