I have a Outlaw 1050 Receiver that has been working great. Last night I noticed some static comming from the rears during CD playback. It was in both rear speakers but not the fronts.
Rear speakers are El cheapo JBL mono driver type. I figure the speakers may be blown or it may be the amp. To debug I unhooked one of the fronts and played it as a rear speaker. The distortion was gone!!

The suprise came when I hooked up the JBL again. The distortion was gone. How can this be?

The only thing that I can think of is.

1. The speaker wire connection was faulty to the JBL. They have the cheap spring clip type of connector.

2. Some kind of charge potential was built up in the wire that was discharged when I unhooked the speaker.

Why did it fix both rear channels when I only unhooked one. I am happy that the distortion is gone but I would like to understand why it is gone.

Any input is appreciated.
