Posted August 5, 201114 yr Is this a ground issue with the plate amplifier? I've been using this Canton subwoofer for quite some time... I have a brother subwoofer which does not do this. I currently have them powered off of my Marantz, so when the rcvr turns on the subwoofers turn on using the 12V trigger. Should I try plugging it into a dedicated outlet??? What do you think it could be???
