so i have come to notice that alot of people have bottom of the line rca cables with there spl setup. so do rca cables make any diffrenece at all whether there a 15 doller pair or a 60 doller pair?

 

Well, yes and no. They're essentially the same, the more expensive ones will last you longer and give you much more as far as EM shielding goes however, so when you cross that power wire, you won't get as much distortion through the head unit signal. A lot of people like the expensive stuff because of better durability (Better ends, better soldering and connections)

 

no, no difference whatsoever.

rca's do nothing but carry a weak signal which is good enough for the spl application.
