Review on 💥 6-Foot Mediabridge Ultra Series Subwoofer Cable - Dual Shielded, Gold Plated RCA to RCA Connectors - Black, Part# CJ06-6BR-G1, Enhanced SEO by Eduardo Murillo

And sometimes not. I recently ran a subwoofer wire from the back of my house through a 40 foot piece of underground PVC electrical conduit to the other side of the house. I did this because I couldn't route it through the attic and didn't want the cable to be visible. I have two powerful subwoofers behind my TV set for my home theater. In the middle of the night, with the amp and TV turned off, the subwoofer started humming. The volume would increase. The house and the neighborhood rumbled. It turned out that the subwoofer cable picks up and amplifies electromagnetic waves from other sources, for example, a large antenna array. The reason was that the cable was not shielded. Or not adequately shielded. I have removed possible causes such as ground loops or feedback from cable TV. Nothing worked. I asked for help from people who make a living solving these problems. An expert in the field told me to throw out all my old cables and recommended the Mediabridge Ultra cable. I tried this; replaced all cables and still no problems. To avoid any possibility of subwoofer malfunction, it pays to use a quality cable, especially if the cable is longer than 4 feet.
