Hum is usually due to noise from bad cables or the wrong settings on the Stereo. I would replace the cables and make sure they are not wrapped around power cords or wall plugs. if you still have hum then I would check your stereo settings to see if you have an option for sub out or frequency cut off
Sorry, there was a problem. Please try again later.I had the same problem when I first hooked up a sub... you only need one wire going to it. Don’t use an rca even though it’ll work. After hooking up the cable correctly.. program the system again.
