I never had the behringer hooked up to the old sub since it had its own plate amp. I just ran the line straight from the receiver to the subwoofers plate amp.
I meant how was it wired from the Behringer to the old subwoofer during the test that I suggested to drive the old subwoofer from the Behringer. Since the old subwoofer worked reasonably well, this suggests there's something different about the connection used for the new subwoofer.
Now I have that same line running into the behringer and am using a neutrik speak on connector as an out to the subwoofer with banana plugs at the end.
My current suspicion would be a poor connection in the neutrik.
(Soldering the cables directly to the speakers might be an option, but not if you haven't had any experience doing that.)
I'm sorry, but I'm running out of ideas for things to try that don't involve electrical test equipment. In particular, a Volt-Ohm meter to measure AC voltages, currents and resistances at various locations in your signal path, along with someone who is familiar with how they're used and what to expect. Which is to say, an on-site visit by someone who does A/V installations professionally. (Not Best Buy!)
