So, I have a NEW JVC 400 watt sub that goes down to 23 dbls.

When I turn the volume on the sub loud enough to even get a rumble out of it, it makes this loud distortion sound that makes the speaker move in and out real fast and sounds like sh*t!

I cant figure out if its a LFE settiing on my 805 or just what the problem is.

Any thoughts or suggestions to help me resolve this? I'm stumped and desperate to resolve this...
