no, cant remember, its been several years. just usually check around for the lowest price.
I used the Magnum Shielding cables. Think maybe denniskirk, but all the prices change.
the namz extensions just made it easy to extend the wiring, but you dont have to use that, just as easy to splice the wires yourself.
I probably spent around 75 for the bars (used) and maybe 250 for the cables.
