any difference between sub and video cable

[hankdog]

I need a sub cable,I was thinking about going with impact acoustics, well I need a 45 foot cable and the guy at impact says to use their 50 foot sonicwave video cable, because as he said rca's are all the same, is he right or should I go with a 25 and 18 foot with an rca coupler.

He is correct in that most any cable with RCA on it will work for you on the sub.
With this in mind, now you need to compare prices of that long of a cable be it video, audio or digital in name and I would suggest the least expensive of the batch

thank you

thank you mtrycrafts, I always thought sub cables were better insulated against rfi interference.

sub cable

Also, 1 long cable would be preferred over multiple short cables with couplers to reduce potential losses or connection issues.
