I got a good deal on a Precision Acoustics PA12XS 12" Subwoofer. I used Acoustic Research AP053C 25' Subwoofer RCA Cable too hook it up.
At first I had the AC plugged directly into the wall, but didn't think that was a good idea. Now I plugged it into a cheap computer power surge bar.

My subwoofer will start humming and it gets louder and louder and then the sub sounds like it relieves itself and its really loud. It does it intermittently and it also does it when it's plugged into the wall. I am curious if anyone knows what the problem could be.
