I went thru this process a few months ago, when I received a pair of JL Audio F113V2 subs.
I enjoy Wireworld cabling for my interconnects and speaker cables and bought a set of their "Oasis 7" cables with RCA connectors to use with my former Velodyne sub, while I was waiting for the JL subs to be available. They were relatively inexpensive, never heard any "hum" using them.
My audio buddy let me know that the JL Audio design converted the "unbalanced" into some other format inside the class D amp, and that it was better to connect them to balanced preamp outputs/cabling, so what the heck, I bought a pair of the same "Oasis 7" cables with balanced connectors. They are eight meters long, not a trace of hum from the F113V2's. I can't remember their cost, but it was modest.
