Replacing Rel Sub Cable


I have a Rel Stentor sub and run my wires from the amp to the sub. (High level input) Can I upgrade this odd cable?

Dem, Can you give me a little more detail in your set up of the racing cones please? I have my Strata III with its
spikes directly into my wood floor and wonder if there is a better set up, (I can live with a few holes in the floor, but not dull sounding gear).
Bmpnyc, I agree...dull is bad, holes are good. I try to get a faster sound verses a softer, less-focused bottom-end. I seem to get better results using BDR's under speakers verses spikes...which was also the result with the Stadium. I triangulate three #4 BDR's /Pits with the Pits' surfaces against the underside of the REL cabinet, the BDR's flat surface against the Pits, and the tips of the BDR's resting on the sub-platform. Before I used the Pits, I used 2"x3"x3/4" pieces of oak with the BDR's instead, (which sounded just as good as the Pits in this application). This gave me just enough height needed to clear the feet attached to the Stadium. I use a spiked sub-platform I made of 2 pieces of MDF sandwiched with 3/4" furring strips creating 6 fairly good sized "pockets" half-filled with sand. I also have 805 Nautilus' and making the REL's faster really compliment these speakers.
Thanks for the details DEM, I will have to read a bit closer later., gotta run.
