Default How to diagnose a sub problem? Amp or driver?

Hi everyone,

I'm wondering how to diagnose a previously (for 2.5 years) working sub, that is now on the "quiet" side?

I have the PA-120, and it's been pretty awesome in my setup. Now it really won't play very loud.

How do I know if the problem is the subs AMP or driver? (Course it could be an issue with the receiver, I guess).

How can I diagnose the problem? Suggestions would be helpful (or links). I did search this subwoofer forum, but there doesn't seem to be a diagnosing thread.
