I'm currently using an SVS bass interface module and it is giving me a very bad hum. I've already isolated it to box by disconnecting the box from everything except the sub and amp. Once I unplug the box from my amp the hum is gone. I've already E-mailed SVS and they said that they're currently working with the manufacturer to resolve this problem. It seems that this problem is extremely rare. So I'm just writing this to see if anyone else has ran into this problem and found a way to solve it. I've tried just taking the box totally out of my system but my bass becomes extremely weak. I put a cheater plug on my amp but that had no effect on the hum. I've also plugged the bass box into multiple outlets and surge protectors as well. This didn't have any effect either. I'd appreciate any help. Thanks.
