Aussie, you are right.. sub cabinets would be a car audio term. It had me confused, thinking the same thing as well. But I just figured he wouldn't be doing that so I just assumed that they were towers or floor standing units he had with a subwoofer in it.

Larry, you're the man.. It is hard to sit down and write out a detailed description on how to do something.. especially for free. I always find myself and others trying to explain a short version and it makes since to the writer but to the one that is trying to figure things out he sometimes has a hard time figuring it out.. good job..
