Checking your connection is always a good idea. Unplug a plug back in a couple of times. Same with the PC. Make sure everything is plugged in, all the way.
Cost nothing to check..

Sound coming from JL Audio F 113
I have had a weird noise coming from my JL Audio sub a few days ago that sounded almost like white noise, or maybe a wind tunnel. It continued when I turned the sub off, not stopping until I unplugged the unit. I plugged it back in and It has worked fine. I heard the sound again for a few seconds when I turned it on today. Anyone have any idea what would cause this. Could it be a capacitor issue? I hate the thought of sending it in for repair.
