Right, I understand. Like I said above output was nil. You have a good point about the driver not being in a box or even a baffle to cancel front / back waves, however, I tested the driver about a year ago with the amp from a computer speaker and it was moving pretty well, I expected at least the same which is why I suspected the signal might need boosting. I had the gain at full crank and turned the LFE channel up all the way while testing.
The amp is just a temp solution, I'll probaly go with an EP2500 in a month or two.
