Years ago my brother in law had a problem that sounds like yours.  I told
him to send the stereo to me and I'd check it out.  It arrived and it worked
great for me.  He also sent the speaker wires.  I noticed they were all
extremely frayed.  Being anal, I re-stripped them to the right length and
tinned the ends.  I sent it back with the report that it worked perfectly
for me.  He hooked it back up again and later thanked me for fixing his amp.

I concluded that the cheap speaker connecting blocks aren't compatible with
frayed speaker wire.  Maybe that's the root of your problem.
