well i didnt read ur post correctly but either way its gotta be your wires. MY sis had that problem and it went away when she replaced her sub so maybe check all ur connections again. The ones going into the actual sub and subbox. Maybe one of those is touching and check all ur power/ground/ inline wires. Check to make sure ur fuse box is hooked up right. Thats about all i can suggest. Maybe try to find a caraudio forum. Most of those guys will be able to get a little more specific. to me it sounds like the amp though.

sounds like a grounding problem for sure. Check your ground, and make sure it's getting a good metal to metal contact, no paint. If the ground connection is to the body of the car, try a different ground location, some have more interference than others. Good luck!
