Well JaY, I'm not to sure whether cable quality really plays a role in car audio RCA's, but I do know for video, if it's an analog connection, cable quality actually does play a difference (with component and composite cables for example) but on a digital signal (HDMI for example) cable quality really isn't a factor until a certain length, which for HDMI is about 12-15 feet. Once you get to 12-15 feet cables you need to start dishing out the extra $ for a high quality cables, for some reason the data doesn't travel well after a certain distance. It's much more complicated then that, but I can't really explain it cause quite frankly I don't really get it. lol.
I might as well though, it's not like the RCA's from Knu are expensive at all anyways, they are actually amazingly cheap(at least in my opinion). It seems I thought this would cost a lot more than it really is going to. Which is ALWAYS a good thing //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
