i have a old school us acoustics amp and it has a left and right chanel in. if i plug both of them in the speakers go back and forth slowly and make a quit thump thump thump noise. if i unplug one of the rca jacks this stops then plug it back in and after a couple minutes it starts again. this goes away if i turn the music up load.

is this magnetic resonence? how do i stop it. im using rg6 coax line with very nice male/female connectors and everything is soldered.

amp prolly needs repair

Sonds like poor power or ground issue to me.

kinda sounds like the amp is putting out DC, like said above it most likely needs to be repaired or replaced
