High level Subwoofer connection


I am in the process of adding a pair of subs to my two channel music system. I plan on using speaker cable from the amplifier speaker output connectors to the high level inputs of the sub (ie, REL recommended).
My questions are:
1. Will the type of speaker cable make any difference (ie., stranded, solid core)?
2. What speaker cable do you recommend using?
In advance, thanks for any thoughts or suggestions you may have.

Since you're simply sending a signal to the sub amp, it shouldn't matter much. I use a single with four 12ga copper conductors inside. I believe they're stranded and tightly twisted. I bought the 20ft cable from another Goner. It works fine for my sub. In the HT room, my Art of Sound sub uses the REL cable w/Speakon connector for R/L speaker support. This cable has thin conductors and they could be silver-plated or tinned. There are folks making new REL-type cables with claims of superior sound. Could be. More than a few choices. Have fun.
The Basic stock Rel cable is horrible. I use a Nordost baseline made to Rel spec and it so much better. Attack and decay you will never hear with the stock cable. the Baseline has 6 X 24 gauge wire.

That said I have not heard the Rel premium cables. But anything is better than the base stock cable
Both SR and AQ make a Speakon cable for REL with the neutrik connector. Wonder if anyone has tried any of these cables and to what effect.
Many thanks
