Sounds like a ground loop.. check your RCA's and ground, you may have knocked one loose, or RCA's are possibly touching..

If everything's in completely/not touching... I'd say swap RCA's and see if that doesn't eliminate the noise. (Provided your grounds are solid.)
Edit: Maybe post some pics of your ground, where it's terminated & attached to the amp? Just my $0.02
