Q
This kit comes with one "set" of RCA cables that would only work for the front/rear speakers. Does a kit come with two RCA cables?
[ Eric  Feb 10, 2016 ]

A
All amp kits, as far as I am aware, only come with a single set of RCA wires. ....an extra pair of RCAs is cheap and Crutchfield will take care of you:-)
[ Barton  Feb 11, 2016 ]
A
By set it means 2 lines...which is 1 pair...it would run either the sub rca input...the left and right of front...or the left and right of rear...if it's a mono channel amp you don't need another cable set...if it's a multi channel amp you will need to by another cables set
