Good cable for our sub
Size: 10 Feet
Bought this to replace a random RCA cable that kept giving us problems. This cable seems to run the sub much better.

Cheap and does the job
Size: 6 Feet
Seems to be well constructed, it’s a little thinner than I expected, but it passes bass just fine to my SVS PB 2000 Pro.
