Subwoofer RCA Interconnect recommendation

If you want something better than the cables on Amazon, I would check DH Labs.  They have two different options.  Even the most expensive model isn't crazy expensive. 

If you go with speaker level connections, the Analysis Plus are relatively affordable. 

How much are you looking to spend? I have no experience with high dollar subwoofer cables. Somebody else on the forum would, I think. 

Quite happy with Bluejeans Subwoofer Cables.

And I have three subwoofers...

sls883: : I am using a Sublime crossover, so I am only sending 80Hz and above to my power amp.  So I am coming directly out of my second set of outputs from my preamp.

Also, I haven't really considered what I plan on spending. If something is inexpensive, I don't care (and would be happy), as long as it sounds good.  If something is expensive, that's ok too, if it also sounds better than the good less expensive cable.

Eichlierera: yes, on another post, someone else also recommended Bluejeans Sub Cable.  That's two for Bluejeans.
