I did the same thing Don I was down on my knees with my ear next to the sub to see if it was working and one thing I can definately tell you is when it is working you don't have to put your ear near it to hear it and you can feel it.
It put out better bass and bottom end than the 15" jbl sub.
I spent many years as a bass player so I judge all things first by the bass response.
Like I said I made that mistake ( not having the sub hooked up) and someone here pointed out that Bose said that is the number one customer service call from new owners.
