I have some Kicker video RCA's laying around and was wondering if I could use these for my amplifier. They say 75 ohm and I think they would work, but I think they would downgrade the signal. I think audio cables have less resistance. What's the deal??? Does it really matter?
It should be fine for car audio. From here: http://forum.ecoustics.com/bbs/messages/34579/123129.html
I dug up my old 200 disc Kenwood CD changer a couple weeks ago and connected it to my Receiver's digital coaxial in with a video cable. Supposedly there is a difference between regular RCA cable and digital RCA, but I haven't had any issues so far.
