Review on Mediabridge Ultra Series 50FT Subwoofer Cable - Dual 🔌 Shielded, Gold Plated RCA to RCA Connectors - Black, Part# CJ50-6BR-G1 by Dawn Webster

This cable is probably fine for short distances and installations without interference, but it didn't work for my 50ft subwoofer wall run as it produced a very annoying hum. I really didn't want to pull that wire out of the walls and attic, so I ran a thorough diagnosis, tried different wires, distances, and line filters, but the cause was eventually narrowed down to the signal wire. After replacing it with another (more expensive) tone disappeared.
