The problem could be as simple as having all your equipment on the same circuit, ore as complex as replacing the sub amp or needing major electrical work (bonding/grounding) to the premises. No reason these subs should incur an extra cost like this in my opinion.
Now...this is from wikipedia, which I know can be somewhat unreliable, but here is what it has to say about the topic.http://en.wikipedia.org/wiki/Cheater_plug
In the professional audio and video fields, the cheater plug has been identified as a serious safety problem. Its casual use as a method for avoiding ground loops in analog audio and video signals (to eliminate hums and buzzes) is dangerous. Bill Whitlock, president of Jensen Transformers, writes, "never, ever use devices such as 3 to 2-prong AC plug adapters, a.k.a. 'ground lifters', to solve a noise problem!" Whitlock relates how an electrical fault in one device that is connected to its electricity source through an ungrounded cheater plug will result in dangerous, high current flowing through audio or video cables. Whitlock notes that in 1997, consumer audio and video equipment electrocuted nine people.
The cheater plug is also recognized as a safety hazard in laboratory settings. For example, in August 2005, Tarun Mal, an associate professor at Cleveland University, was electrocuted when he plugged a defective fluorescent lamp into a lamp timer using a cheater plug. Subsequently, the state of Ohio issued seven citations to the university for unsafe electrical conditions. The Scientist notes that four of the University's seven environmental safety experts agreed that use of the cheater plug "is not uncommon in US university labs". Jim Kaufman, CEO of the Laboratory Safety Institute, says, "When you inspect labs, it's not unusual to find anywhere from one to seven that way.
I'm not adding this to "dis" anyone. I just don't want anyone to get shocked or worse...
