Ok its a cerwin vega sub (avs 632; 100w powered) and its not just humming...its screaming! I can't even turn up the volume only but a tick and this thing takes the pictures off the walls. I cannot use it at all...I tried unplugging the components from the receiver (HK avr100), directly plugging the sub into the wall, using one of those "cheater plugs", I've also tried using different rca cables too...no luck.
I'm trying to hook it direct line level from my receiver...
